How to properly solder with a soldering iron with solder and rosin

If in Soviet times there was a game for schoolchildren, the essence of which was to solder a radio-electronic microcircuit on their own, which they successfully did, but now the question of how to properly use a soldering iron puts many in a difficult position. Although learning how to solder with a soldering iron is not so difficult, and having mastered the basics for “dummies”, you will be able to carry out simple work on your own without turning to specialists.

Soldering with a soldering iron

In order to start soldering, you need to prepare a workplace and the necessary tools. Regardless of the type of proposed work, the following requirements are imposed on the workplace:

• The presence of good lighting will allow you not only to work comfortably, but also to notice small flaws in the soldered parts, which is difficult if there is a lack of light;
• No flammable items;
• Free working space on which you can easily place the part to be soldered;
• The presence of ventilation will make work not only more comfortable, but also safer; inhaling molten rosin has a negative effect on the respiratory system;
• A magnifying glass makes it possible to work even with small parts and thin wires;
• A simple stand solves the problem of placing a heated soldering iron.

The next stage of preparation will be the choice of tool, and a beginner is always faced with the question of what is needed for soldering with a soldering iron.

Soldering iron selection

The basis of high-quality soldering is heating metal parts to the soldering temperature; accordingly, for each type of work it is recommended to use soldering irons of different capacities:

• For soldering radio components and microcircuits, it is best to use a soldering iron with a power of no more than 60 Watts, otherwise you can overheat the part or simply melt it;
• Parts up to 1 mm thick will warm up better when using a tool with a power of 80-100 Watts;
• Parts with a wall thickness of up to 2 mm require greater power and some experience in operation, so soldering of such parts will not be considered in this article.

Almost every man, be it an ardent fan of delving into radio equipment and electrical appliances or a simple owner who is faced with a situation in which the process of joining metals and wires is required, sooner or later will be forced to use a soldering iron, in this case you can to cope with the task yourself .

• Devices and tools required for the soldering process
• Recommendations for competent work with a soldering iron using rosin
• Correctly soldering with a soldering iron with rosin: general recommendations

Devices and tools required for the soldering process

In everyday life, when it is necessary to repair something basic, special experience and expensive units and tools for soldering are not required. The main ones are the following devices and tools:

1. Soldering iron. The main criteria when choosing it are the size, which must correspond to what you are going to solder, otherwise there is a risk of damage to adjacent circuit elements or poor-quality soldering of wires and power (it is advisable to purchase a pair of soldering irons, one for 25 watts for soldering microcircuits, the second for 40-watts). 60 watts in order to solder wider parts of parts).
2. Soldering iron stand. When working with a soldering iron for a long time, you have to frequently unplug it to avoid overheating, then wait until it warms up again. Due to the fact that the soldering device heats up to 300 degrees, you simply cannot do without a stand for it.
3. Rosin and solder. Rosin is an amorphous substance obtained from the resin of coniferous trees, very fragile under mechanical shock. What is rosin needed for? When soldering, it is used to degrease the surface and remove oxide films. Solder is an alloy of two metals - lead and tin for soldering.

Preparing tools and materials for soldering

Soldering is the process of joining parts by introducing molten metal of a lower temperature into the area of ​​their contact. Before you start soldering, you need to carefully prepare for work:

1. Preparing the soldering iron for subsequent use. The main task of all manipulations is to cover the working area of ​​the soldering iron tip with a thin layer of solder. Method 1: when the soldering iron is first heated, its tip must be cleaned, thereby protecting it from oxidation and wear. Having warmed it up to operating temperature, you can touch the sting to the rosin, melting the solder on it, and then rub it on a wooden surface.

   Method 2: wipe the heated tip of the soldering iron with material treated with soldering acid, melt the solder and distribute it over the tip with a piece of solid ammonia using the rubbing method.

2. Preparing parts for soldering.
3. Regardless of the type of soldering (low-temperature or high-temperature), the surfaces of the parts must be thoroughly cleaned of oily and greasy contaminants and degreased using rosin or solvents. If there is rust, it must also be removed by any mechanical means. If you need to solder the wires, it is better to twist them together first, since tin is a rather soft metal that may not withstand even the slightest load.

Recommendations for competent work with a soldering iron using rosin

Rosin easily dissolves in organic compounds such as alcohol, acetone and others. When heated to 150 degrees, it is capable of breaking down chemical elements such as tin, lead, and copper.

Rosin is used in radio and electrical repair work as an antioxidant component for soldering. Its proper use will significantly reduce the spreading and surface tension of the solder, destroy the oxide film and prevent the formation of a new one.

Before you start soldering the necessary elements, you need to clean and then tin the contacts. To do this, place a piece of solid rosin on the part of the surface that will be soldered and press it with a soldering iron heated to the required temperature.

Correctly soldering with a soldering iron with rosin: general recommendations

If the task is to solder a microcircuit, then you need to dip the soldering iron tip in rosin and coat the twisted wires with it, which will ensure free flow of tin to the soldering site.

If the solder was not used in sufficient quantity and a part of the twist or wire is visible in some places, it is necessary to repeat the previous step.

Next, having placed the solder at the soldering site, it is recommended to run the soldering iron tip over it, as a result of which it will melt. If the material is processed poorly, then it is possible that the solder will not adhere to the surface .

Of course, it is possible to solder without using rosin, but the quality of the soldering joint and the aesthetic appearance of the product will be lost.

If rosin is not available in everyday use, soldering acid, electrolyte from an old battery, pine resin dissolved in acetic acid, or acetylsalicylic acid may be useful as a replacement.

And yet, the best solution is not only to use rosin when soldering, but also to use it in excess for more reliable bonding. Until the composition hardens, do not move parts of the solder.

With effective tinning, soldering will occur almost instantly ; you just have to wait until the solder has completely cooled. On many Internet sites you can find videos with simple lessons on how to use a soldering iron and learn how to solder. If you follow the detailed instructions, then the process itself is not particularly difficult; to achieve a positive result, you just need to do everything clearly and consistently .

When thinking about how to properly use a soldering iron using rosin, do not forget about the need to carefully prepare tools and parts for the soldering process. When creating a permanent connection, the solder layer must be protected with rosin. For each individual soldering case, a soldering iron of the appropriate size and power may be suitable. When parts are connected correctly, soldering becomes reliable and durable.

How to solder correctly with a soldering iron: what is required for soldering using rosin - Machine

In the modern world, saturated with electronics and electrical appliances, you need to know how to use a soldering iron. This skill will save a lot of time and money on repairing broken appliances. Despite the apparent complexity of this process, it is actually very easy to learn how to solder correctly with a soldering iron.

Soldering technology is to use a metal that has a lower melting point to connect more refractory metals.

Soldering irons

Soldering irons have several types, differing from each other in the heating method. According to this criterion, they are divided into electric, hot-air, induction, and hammer. The most popular in everyday life are electric soldering irons with a spiral or ceramic heater.

For each type of work you need to use a soldering iron of a certain power. For example, for soldering electronics, you will need a low-power soldering iron up to 40 W, and for parts with walls up to 1 mm you will need a more powerful device up to 100 W.

To solder together parts with a thickness of more than 2 mm, you will already need an electric hammer soldering iron with a power of 200-550 W. Such a device is unsuitable for everyday use, as it is intended for large-scale work and has a huge price.

Solders

Solder is essentially an alloy of metals with a low melting point. Solder usually contains tin, but due to its high price, a cheaper material, lead, is added to it.

Also, solder often contains auxiliary substances that are used to improve soldering strength or reduce the melting point.

Soft solders marked from POS-18 to POS-90 are very popular. The number in this abbreviation means the percentage of tin in the solder.

Hard solders are rarely used at home. They contain copper and zinc, which allows the solder not to melt until the temperature reaches 450˚C.

You need to know that solders with different compositions are suitable for different types of metals. For steel, POS-41 is better suited, for copper almost any solder is suitable, and for stainless steel - tin solder with cadmium.

It is best to determine what metal will be used for soldering before purchasing solder and, based on this information, purchase the appropriate solder.

Flux

Flux is an auxiliary substance that is used to free parts from oxidation products during soldering. Fluxes also contribute to the spreading of metal during soldering.

There are a huge number of soldering fluxes on sale. There are both neutral and metal-active fluxes to varying degrees.

The most popular base for flux is rosin. It is fusible and begins to boil already when heated to 250 ˚C.

• To learn how to solder with a soldering iron with rosin, you must know that after soldering you must completely remove the remaining rosin from the metal, otherwise oxidation of the metal will occur at this point.
• Also, due to its hydrolyzing properties, rosin increases conductivity at the soldering site, which disrupts the operation of electronic devices.
• It is also best to select the flux for the type of metal with which you plan to work - this will ensure high quality work.

Pastes

Solder pastes or tinol are a mixture of solder and flux. The paste is used for soldering in complex, hard-to-reach places. Tinol is also convenient to use for beginners without experience with a soldering iron.

Tool preparation

Don’t be afraid if the new soldering iron starts to smoke when you first turn it on. This occurs due to the burnout of the oil that preserves the instrument during long-term storage.

Before using a soldering iron, you should prepare its working part - the tip. It can be forged a little or sharpened to the required shape. If the working part of the soldering iron is coated with nickel, then such preparation is strictly prohibited.

The stores have a wide range of tips or tips for soldering irons, differing in sharpening. For large parts, a round tip with an angular sharpening is suitable, and for small parts, a sharp conical one.

If the soldering iron has a tip made of copper, then before work you need to tin it during the first heating. Tinning can be done by rubbing molten solder over a heated tip with a wooden block or by any other method.

The main thing is that upon first use the working part of the soldering iron is covered with a thin layer of solder. Otherwise, the soldering quality will be poor and the working part of the tool will be damaged.

Preparing parts

The preparation of parts does not depend on the metal from which they are made or the method of soldering them. Preparation always follows the same scheme - first the part is cleaned of contaminants and degreased.

For this purpose, use gasoline, acetone or other solvents. Rust must also be removed mechanically.

Temperature

The temperature of the soldering iron is the main parameter when working with it. When working with an insufficiently heated tool, the solder does not melt, but forms a lump.

To determine at what temperature you should solder, you need to know the melting temperature of the metal of the part and the solder. The temperature of the soldered parts should be 40-80 C˚ higher than the melting temperature of the solder, and the temperature of the tool tip should be 20-40 C˚ higher than the soldering temperature.

If the soldering iron does not have a temperature control function, then this parameter can be assessed using rosin. When touched by a soldering iron, it should boil, without instant combustion. Overheating will be indicated by the appearance on the solder, after touching it with a soldering iron, of a dark film consisting of oxidation products.

Soldering technique

1. Basically, soldering occurs in two ways: by applying solder to the parts using a soldering iron or by applying solder directly to the parts.
2. When using any of the methods, you must first clean and degrease the parts, secure them, heat the tool and treat the soldering area with flux.

If you are using a soldering iron to apply solder, melt a small amount of solder at the tip and transfer it to the soldering pad. Next you should move along the junction of the parts.

• If solder is applied directly to the junction, then the parts are first heated with a soldering iron, and then solder is supplied there later.
• If you plan to solder circuits, then it is better to find high-quality photo instructions on how to solder electronic circuits.

To evaluate the quality of work, you need to evaluate the color and shine of the junction. A high-quality solder has a pronounced shine; if the solder is burned through, it has a matte color and a fragile structure. The spongy structure of the solder indicates a defect.

For the first tests, it is best to use simple and inexpensive materials. The easiest way is to understand how to solder with tin and rosin correctly.

How to solder correctly with a soldering iron and rosin

Every novice radio amateur sooner or later has to acquire a minimum set of tools and learn the basics of soldering with a soldering iron. To get the job done quickly and with the highest quality, you need to master rosin soldering.

1

How to solder correctly with a soldering iron and rosin

In order to get started, you need to purchase the following minimal equipment:

• electric soldering iron;
• tin or solder;
• rosin.

Regarding the power of the soldering iron, a regular 40 W (voltage 220V) will do. For home use, such a soldering iron is quite sufficient. Now solder - you will need it in order to connect the components and parts. Solder can be different: rosin, an alloy of tin and lead. It is sold in the form of tubes (with flux inside) or in the form of wire. The last option is better.

As for the choice of solder, in terms of hardness and melting point, a flux labeled PIC (tin-lead solder) is suitable; 60 is the percentage of tin, and 40 (this figure is not indicated, we calculate it ourselves) is the amount of lead in this solder. It's good if you can find solder with a high lead content (it differs in color, it will be darker). The melting point of such solder is an order of magnitude higher, which means increased soldering strength.

And finally, about fluxes - this substance is intended to remove oxides from parts being soldered. This cannot be avoided, because the tip of the soldering iron is copper and will oxidize when heated, so you will have to periodically remove carbon deposits. If this is not done, the solder will not attach to the parts, but will simply spread. Soldering with such a contaminated tip will not work.

The simplest and most reliable flux is rosin. The material is natural, because rosin is made from pine resin. This is an amber-colored liquid with a pleasant pine aroma. Sold in pieces in pure form, in the form of viscous or liquid flux. For beginners, both pure rosin and alcohol-rosin flux are suitable; this is a universal material consisting of a solution of rosin and pure ethyl alcohol.

How to solder with rosin

Everything you need has been purchased and prepared; you need to clean the soldering iron tip (and if it is not flattened, do it yourself). The thinner the tip, the more delicate soldering work can be done. The angle of the tip should be dihedral 30-45 degrees.

How to solder with rosin:

• Open the window; you need to work in a well-ventilated area.
• Turn on the soldering iron, wait until the unpleasant smell and characteristic smoke go away - the tip is calcined and ready for use.
• You can turn off the soldering iron for now to clean the tip.
• Turn on the electrical appliance again and wait for the tip to heat up.
• You can lightly tin the part clamps (touch the rosin with a hot tip several times so that the tip is covered with solder) to ensure high-quality adhesion of the parts being soldered.
• Take the rosin, touch the tip of the tip to the rosin to pick up a little solder. Wait until it warms up. It will take literally a few minutes.
• Place the sting on the pine board for a few seconds, then repeat your actions again.
• After a few repetitions you will succeed.
• For a beginner, when mastering the basics of soldering, it is more convenient to work so that the tip is exposed; this is the most basic mistake when working. Due to the large exposed tip, the circuit often catches fire.
• When working with copper wire, one tinning is enough, that is, you need to warm up the tip, touch the rosin, apply the tip to the working surface, lift the wire, lower it into the rosin, apply the hot tip to the surface and lift the wire.
• As a result of these actions, the rosin will begin to smoke, and the wire will flow around the rosin mass. After this, you will need to cover the soldering with tin and transfer it to the wire.
• If, as a result of the actions taken, the wire changes color from yellow to silver, this means that everything was done correctly. To solder 2 wires, you need to tin both.

Rules for soldering copper wires

One of the best ways to connect copper wires is soldering. It provides high strength and electrical conductivity. At the same time, soldering is easier to carry out than welding, and it is more reliable than simple twisting. Although the wires in junction boxes are often connected using self-clamping terminals such as WAGO, soldering techniques will not hurt any electrician to know.

You can learn how to solder copper wires in a few minutes, having all the necessary materials and equipment.

The essence of the process

The essence of the soldering process is that metals are joined together using an alloy that has a melting point lower than the melting point of the substances being joined.

During soldering, materials are heated to the melting temperature of the solder. This ensures very strong adhesion (sticking) - the property of materials to adhere to each other at the molecular level.

However, the main parts do not melt and mix with the solder material, as happens when welding using filler material.

Soldering iron and solder

Soldering irons are traditionally used for soldering copper wires. There are several types of them, including electric and gas. Soldering of copper wires is carried out using an electric soldering iron with a copper tip. This tool consists of a copper rod, sometimes nickel plated, that is mounted in a heating element housing.

The heating element operates on direct or alternating current. The supply voltage can vary from 12 to 220 V. For soldering copper wires of electrical wiring in the house, the most common soldering iron with a power of 60 W is suitable. If you need to solder thin wires of an electrical appliance, then a less powerful tool will do. It is important that it heats the copper material well and melts the solder.

To ensure high soldering quality and joint strength, it is necessary to remain still while the molten solder cools. You can hold the wires with your hands, but it is more convenient to use tweezers or clamps.

Tin-lead solder is used for soldering copper wires. Most often this is POS-61, but you can also take POS-40. The marking indicates the composition - tin-lead solder with a tin content of 61%.

Solder is usually produced in rods with a diameter of about 8 mm or in the form of solder wire with a diameter of 2 mm. General purpose solder is often used for soldering copper wires, which looks like a hollow tube of tin-lead alloy. Inside such a tube there is flux powder.

Application of flux

In order for the solder and the wire material to interact with each other, and the connection to be high-quality, the wires must be cleaned of the oxide film and only then soldered. For cleaning, you can use sandpaper, and for subsequent processing, use a special substance - flux.

Flux will not only clean copper wires, but will also create a thin protective film that prevents oxidation of the material.

It is allowed to use both solid flux - pine rosin, and liquid - various types of soldering acids or a homemade composition.

Sometimes, in order to correctly and firmly solder copper wires to each other or to any metal object, they use only liquid flux. You can prepare it by dissolving ordinary pine rosin in ethyl alcohol.

Soldering acid is prepared independently by dissolving zinc granules in hydrochloric acid in the proportion of 412 grams of zinc per 1 liter of acid.

But it’s better to buy ready-made flux that meets all quality standards, since bringing acidic compounds to copper wires is undesirable.

How to solder correctly

To reliably solder copper wires, you need to prepare a soldering iron. If you do not tin the tip before work, the solder will not stick, but will roll off the rod in balls. This happens because the tip is covered with a layer of copper oxide and carbon deposits formed during previous soldering.

Preparing the soldering iron

For ease of work, some specialists sharpen the tip with a flat file to give it the shape of a spatula or flat screwdriver. The sharpening angle should be 45-60 degrees.

A non-burning tip (eternal) cannot be sharpened under any circumstances; special sponges are used for it.

The mechanically cleaned tip must be heated and then tinned. To do this, it is coated with flux.

If the flux is solid (rosin), simply immerse the tip in it. The rosin will melt and cover the heated surface. After this, you need to touch the solder bar with a soldering iron and heat it up. The molten solder will coat the tip, protecting it from further oxidation.

The procedure for tinning a soldering iron must be repeated as carbon deposits form on it. This happens because the temperature of the tip is much higher than the melting point of the solder, and over time it begins to burn. To reduce the likelihood of this happening, it is recommended to use a soldering iron with temperature control.

Preparing the wires

The copper wires to be connected also need to be prepared for soldering. First, remove the insulation from the ends at a distance of about 4 cm, strip them, twist them together and tinning them. Copper wires can be tinned as follows:

• heat the twist with a soldering iron;
• coat with flux;
• Apply a small amount of solder, spreading it over the surface of the wire.

The actions are similar to those performed when tinning a soldering iron tip. If you are going to solder stranded copper wires, then you must stock up on liquid flux, since it will be very difficult to cover the entire surface of the copper “hairs” with molten solid rosin. To get a quality connection, you need to heat the stranded wire and then dip it in liquid flux, which will wet the entire surface intended for soldering.

Further, soldering of stranded and single-core copper wires is carried out in the same way. The two or more conductors being joined are heated together and solder is applied to them. After applying it, it is necessary to ensure that the joint remains motionless while it cools. It is not allowed to accelerate cooling by wetting it or blowing air on it.

Copper and aluminum connection

When connecting copper and aluminum wires by soldering, you can encounter many difficulties, which can only be overcome by using alternative connection methods.

The fact is that both aluminum and copper are covered with an oxide film in air.

And if these films themselves do not affect the state of the conductor in any way and even provide fairly good conductivity, then when combined they contribute to the occurrence of a powerful chemical reaction.

Under the influence of moisture contained in the air, at the point of contact between aluminum and copper oxides, the process of electrolysis begins, that is, an electric current is formed due to the fact that the ions of both materials have different electrical potentials.

Electric current is the movement of charged particles - ions, and during their movement, metals at the point of contact are destroyed. At the same time, aluminum is more destroyed. Destruction causes the contact to deteriorate, and subsequently the electrical resistance of the connection increases and it heats up. With severe corrosion, when direct contact between the two materials has already been lost, an electric arc occurs, which completes the destruction.

It is recommended to connect copper with aluminum only through a third, neutral material. Most often, steel terminal blocks or clamps are used for this.

How to solder correctly with a soldering iron

Many breakdowns can be repaired yourself; all you need to do is equip yourself with a soldering iron. With minimal skills, you can solder loose wires and parts and thus restore the functionality of the device. The question often arises, how to learn to solder? In fact, it’s not that difficult, the main thing is to get the hang of it. With a little experience, you can carry out home repairs on almost any device where the essence of the breakdown is torn and disconnected parts.

What do you need to learn to solder?

To solder anything, you first need to prepare a work area. The part itself should be located on it, as well as the place where you will put the tool. Please note that the soldering iron heats up to high temperatures, so it should not be placed on plastic or other flammable objects. The best solution would be to use a metal or ceramic stand.

It is also worth taking care in advance of those tools that may be needed during the work. These can be pliers for holding large objects or tweezers for fixing small parts.

Additionally, you need to have a damp sponge on hand; use it to remove the remnants of old solder on the tip.

If all of the above are recommendations rather than mandatory items, then  three elements are always required for soldering:

• the soldering iron itself is a tool whose tip heats up to high temperatures and is capable of melting solder;
• solder - a metal or alloy that melts at relatively low temperatures and is capable of conducting current (most often it is tin);
• flux is a substance that has degreasing and oxidation-preventing properties.

The principle of soldering is extremely simple and has remained unchanged for many years.

There is a simple diagram of how to solder correctly:

1. Cleaning parts from old solder. This point can be omitted when repairing modern (mostly Chinese) devices - there is so little solder in them that if they break down, the place remains almost clean.

2. Degreasing the tip and parts. For this, either liquid flux or rosin is used. This must be done to ensure that the tin attaches to the items. First, the parts and the soldering iron itself are treated with flux, after which they are evenly coated with solder. This process is also called tinning.

3. Melt the tin and put the required amount on the tip. This moment requires some skill. Most beginners fail to take the required amount of solder, which is why the parts are either not soldered at all, or the work done does not look neat.

4. Holding the parts to be soldered together, transfer solder to the joint. At this stage it is important to hold objects clearly. If your hand shakes, the parts will come apart and the procedure will have to start over. It is important to hold the parts until the solder hardens.

How to solder with a soldering iron with rosin?

Rosin is considered a classic substance used in soldering. The whole principle of operation remains the same, the main differences are noticeable only at the degreasing stage.

The peculiarity of rosin is that it is a solid resin. Most often it is in a small metal jar with an airtight lid.

Despite the variety of modern liquid solders, rosin still remains a popular material. Many radio amateurs are confident that only with its help can high-quality and fast soldering be performed.

The peculiarity of how to properly solder with rosin is that you need to press the tip and wires against the resin itself. After this, solder is applied. The goal is to achieve uniform coverage of the part with solder.

When choosing a flux in this way, it is worth considering one point. Rosin is not compatible with all metals, so for complex soldering it is worth choosing a different flux that is suitable for all parts.

How to solder wires with a soldering iron? Work specifics

The soldering technique differs slightly depending on what exactly is being worked with. Working with various parts and circuits has its own specifics due to the size and characteristics of the fastening.

The process of soldering wires is distinguished separately. It is slightly different from the process of attaching regular parts. There is a certain inconvenience in this work - the wires are flexible and movable, so they must be tightly fixed when soldering.

Here's how to solder wires:

1. Strip the wire. The size of the cleared space should correspond to the soldering area. If you expose too little of the reins, it will interfere with your work, and if you expose too much, it may cause a short circuit.

2. If the selected wire is stranded, you need to twist it tightly so that all the wires are adjacent to each other. If you don't do this, some of them may not attach. In this case, not only will the quality of the connection deteriorate, but the risk of breakage will also increase.

3. First, the soldering iron is tinned, then the wire itself. When using rosin, this is conveniently done by immersing it in the resin and heating it with a sting. It is necessary to achieve uniform coverage.

4. The wire is attached to the place by applying solder and fixing until it hardens.

You can also connect the wires to each other using a soldering iron. Before soldering, the wires are stripped and twisted together. Only after this is tinning and soldering done (solid rosin is most often used, but liquid solder can also be applied with a brush).

It doesn’t really matter what kind of wires you use: either copper or aluminum can be easily soldered.

There are several simple methods on how to learn how to perform such work efficiently. The classic and most effective option is to use wire. Twelve identical sections are cut from it, after which a cube is formed by soldering. The design is tested for strength by squeezing the cube in your fist. If not a single edge has fallen apart, the job is done correctly. In the opposite case, a new set of wires is cut and the model is soldered again.

Features of how to solder microcircuits

The specificity of the microcircuit is the small size of the parts, as well as the high probability of their overheating. It is very important to remove the device quickly. If necessary, a heat sink is used - tweezers or another metal object can act as it.

For such work, it is worth choosing a soldering iron with a small tip, since there is a very small distance between the parts. There are several soldering methods. Some craftsmen prefer to make indentations in the soldering iron tip, others connect using a special solder paste, and still others methodically solder the taps one after another.

To understand how to properly solder a particular part, you need to determine what temperature needs to be applied. Much depends on the material from which the board is made. Most often it is 200-300 degrees Celsius.

How to solder the boards largely depends on their design. Simpler circuits are easily connected by alternating solder wires, but complex modern chips require special care - after all, by soldering the next part you can easily eliminate the previous one.

How to solder with a soldering iron with acid? Features of work

Some craftsmen are confident that using acid is much simpler and more reliable than soldering with rosin. However, the use of such a substance can lead to corrosion of the installation.

The use of soldering acid plays a big role when there is a need to remove the oxide film from surfaces, which leads to a better and more durable connection.

This material is suitable for processing connections of cast iron parts, as well as all kinds of precious and ferrous metals.

The main instruction on how to properly solder with such flux is compliance with safety precautions. The type of acid chosen must clearly correspond to the material you will be joining.

It is also worth taking care of the safety of surrounding objects - a drop of flux can corrode some objects, as it is an aggressive chemical.

This flux can be made with your own hands or purchased in a store. For beginners, the second option is preferable, since the composition will not only be uniquely effective, but also, of course, suitable for your parts. In this case, you can always turn to a consultant for help and clarify the correct choice.

How to solder correctly with a soldering iron: what is required for soldering using rosin

Whatever innovations the modern market of tools for repairing radio equipment offers, the soldering iron remains one of the most reliable and safe devices.

The process of soldering wires and microcircuits is considered effective because it allows you to achieve the strongest possible connection between wires and small parts.

This result can be achieved by adding a special material to the contact area - solder, which has a lower melting point than that of the parts being connected.

Thus, soldering with a soldering iron is the effect of a certain temperature on different metal surfaces for their strong and high-quality connection. However, before you start working with a soldering iron, you should first understand the rules of soldering and other intricacies of this process.

What you need for soldering with a soldering iron

To solder something, you first need to prepare all the tools necessary for this process.

• Of course, you will need a soldering iron itself. For working at home, the best option would be a soldering iron with a power of 15 to 30 watts. The choice of device power directly depends on what exactly you plan to solder. For simple parts, a soldering iron with a minimum or medium power is suitable, while for more professional soldering, a 40-watt device will be most practical.
• You will definitely need solder, which is very important to choose correctly. The main function of solder is to create a permanent connection during the soldering process. Currently, there are several types of solder that are designed to solve different problems (copper, silver, tin, lead, etc.). However, rosin is quite suitable for sealing contacts in a microcircuit or for ordinary connection of wires. It is not recommended to use it in electrical engineering, since the acids contained in rosin can simply destroy contacts and destroy complex parts of the circuit. It should be remembered that only correctly selected solder can provide the best connection of parts.
• When working with a soldering iron, to clean and tin the “tip” of the device, you will need to use flux - a special mixture of organic or inorganic origin necessary to remove acid particles released by solder from the tip of the tool. Flux comes in powder, liquid or paste form. Despite the huge selection of different fluxes, the flux made from rosin is considered the most versatile and most effective.
• In order to use a soldering iron with maximum convenience and comfort, you should prepare a special stand for it. Since the device has a very high heating temperature, in order not to burn things or objects, it is necessary to prepare a stand that can withstand high temperatures.
• You will need a file. To make the soldering process simple, you need to sharpen and clean the soldering iron tip with a file. The main thing is that the “tip” of the tool is smooth and has no signs of carbon deposits.
• Also, to work with the device you will need a vice or pliers - with their help you can clearly fix wires or boards and guide them to the desired position during the soldering process. If these tools are not at hand, as a last resort you can use tweezers.
• After finishing working with the tool, you will need to use alcohol, which can be used to wash off traces of flux.

Having all the necessary tools at hand, you can start working with a soldering iron .

How to solder correctly with a soldering iron and rosin

Rosin has such unique qualities as ease of dissolution in various organic compounds, for example, acetone or alcohol. When heated, this substance can break down complex chemical compounds such as copper, tin or lead. Therefore, proper use of rosin helps reduce the likelihood of spreading of the substance, destruction of the oxide coating, as well as high-quality tinning of soldered elements.

You also need to take into account that the thinner the tip of the soldering iron, the easier it will be to work with it, especially when it comes to soldering very thin wires and parts. Therefore, if it has not yet been sharpened, this should be done before starting work.

Process description

• First, you should prepare the workspace where you plan to seal the parts. To do this, you need to open the window, since the fumes that come from the solder heavily pollute the air. You should also take any sponge, soak it thoroughly in water and place it as close to the soldering iron as possible. Well, in order not to stain your work area with drops of solder, it is best to cover the surface on which you will be working with thick cardboard or some other similar covering.
• There must be a stand for the device at hand.
• Then you need to plug the soldering iron into a power outlet and heat it up. As the device heats up, a specific smell and noticeable smoke may appear - this is normal. The device will be ready for use immediately after the tip is completely heated and the smoke and unpleasant aroma have evaporated.
• After the tool has been calcined, it should be turned off. This is necessary in order to pre-clean the tip from dirt and plaque. It is best to clean the instrument while it is hot. To do this, you can use a prepared sponge or cloth.
• Then you need to turn on the soldering iron again and let it warm up thoroughly.
• After cleaning and heating the tool, you should carry out the process of tinning the tip of the soldering iron - covering the tip with a light layer of solder, in this case rosin. Thanks to this simple manipulation, the heat transfer between the parts that are intended for soldering will significantly increase.
• Next, you need to dip the tip of the heated device into rosin for a while so that a little solder accumulates on the tip. You should wait a little while until the solder heats up and begins to soften.
• Excess rosin can be removed using cardboard or other available tools.
• If you plan to solder one copper part, then one tinning will be enough - you need to touch the rosin once, then apply the tip of the soldering iron with solder to the working surface and wait a little until the wires are covered with solder. As a result of these manipulations, the rosin will begin to smoke, and the soldered parts will flow around the molten substance.
• In order to solder two parts efficiently, they also need to be tinned separately, that is, covered with solder. It should be remembered that the tinning process is a mandatory procedure, without which it will not be possible to properly solder the necessary parts.
• After finishing work with the soldering iron, while it is still warm, you need to remove the remaining solder. To do this, the tip of the tool just needs to be wiped with a damp cloth, or better yet, a sponge soaked in alcohol or any other composition intended for these purposes.

There should not be any particular difficulties when working with the tool. For everything to go smoothly, it is best to first practice working with rosin on parts that you won’t mind throwing away later. After all, experience always comes with practice.

In order to correctly solder copper wires using rosin, you must follow a certain sequence of actions.

• First prepare the wires . To do this, the ends of the wires that need to be soldered must be thoroughly stripped of insulation. All wires spliced ​​together are usually insulated using a special heat-shrinkable tube. If such a tube is present, then it must be cut using a sharp knife so that the length extends 2-7 mm beyond all seams. The insulating coating should be about two centimeters on each side of the wires being connected. The exposed ends of the wires must be burned to completely remove the insulation.
• Then the connected ends of the wires need to be provided with a high-quality mechanical connection. To do this, the two ends of the wire are twisted together so that their centers intersect tightly with each other. After this, the end of one wire should be twisted along the length of the cable. The same manipulation should be done with the second end of the other wire.
• Then you need to heat up the soldering iron to first tin the wires and then warm them up. To do this, a heated soldering iron is lowered into rosin and a little solder is taken, after which the device is passed a couple of times along the ends of the wire. During tinning, the wire should be rotated and heated, which will help ensure an even coating of rosin.
• At the end of the work, the finished wire should be insulated . To do this, you need to put the heat shrink back on the already soldered wires. This will not only help cover the connection, but also heat it, making the soldered wire strong and flexible.

As you can see, there are no particular difficulties with soldering wires using rosin. The main thing is not to forget to tin the wire and check the quality of the soldering. If necessary, tinning should be repeated several times until the wires are firmly connected with solder.

Important Tips

Having figured out how to use a soldering iron, you should consider several recommendations for working with this tool.

• Before starting work, to ensure high-quality soldering of parts, you should always clean the tip of the tool. You need to understand that only thanks to the soldering iron tip the thermal conductivity and quality of the connection are enhanced. You can use a damp sponge for cleaning. After cleaning, the tip of the device should be immediately dipped in rosin so that it is covered with a thin layer of solder, which prevents oxide deposits from interfering with high-quality soldering of parts.
• You should always solder small and thin parts first, since the tip of the device at the beginning of its use will be as thin and precise as possible.
• Before soldering parts, their surface must be thoroughly cleaned of dirt and acid. Cleaning the surface of soldered objects is done using a sharp tool - sandpaper or a regular knife. This is done until the surface of the wires noticeably brightens. After which the contacts are tinned and connected using solder.
• If you need to solder some part without using a soldering iron, you can use rosin, previously dissolved in alcohol. The resulting mixture can be applied to the desired surface using any thin tool, such as a screwdriver.
• The highest quality soldering can be achieved by using solder with rosin.
• In order to correctly and tightly solder wires and other parts using solder, you first need to heat the joints with a soldering iron.
• The mistake of many is poor heating of the soldering iron. If this happens, the parts do not connect well. Therefore, before you start using the tool, you need to warm it up thoroughly.
• However, severe overheating of a soldering iron with maximum power can also negatively affect the quality of work. You need to understand that there are different temperature conditions intended for a specific type of work.
• Soldering temperature is a very important nuance. For example, to seal various microcircuits, the temperature should be no more than 250 degrees. But in order to connect radio components, you will need to heat the soldering iron to more than 300 degrees.
• When working with electrical appliances, safety precautions must be observed. To do this, you need to make sure that the window is open and the socket is working. This is due to the fact that when working with solder, harmful chemical elements are released that negatively affect health. As for the serviceability of the outlet, this is also a very important point - in the process of severe overheating, fires often occur. Therefore, the workplace must first be prepared and secured, and only then can we begin to work.

If you take note of these little tricks , the process of soldering parts will go quickly, and most importantly, with high quality.

A soldering iron is a universal tool with which you can quickly connect broken wires or contacts, as well as quickly repair a microcircuit or connect light metal surfaces.

The ease of operation of the device allows any man to learn how to use it in the shortest possible time.

And what is important: working with a soldering iron does not require any professional skills.

Solder

solder is used to connect the surfaces of components and parts to each other - an alloy of lead and tin in various proportions.

As a rule, solder is made in the form of a wire or tube filled with flux. It is better to give preference to solder in the form of a wire, since flux will have to be used in any case.

Typically, solders differ in melting point and hardness, and are marked with alphabetic and numerical values, for example, POS-60.

POS - tin-lead solder, the number 60 means the percentage of tin in the alloy, respectively 40% lead. The more lead in the solder, the darker it is and the higher the melting point of the solder. For home use, it is better to purchase POS-60 solder with a melting point of about 190 °C, and also has good strength.

Fluxes

Fluxes are designed to dissolve and remove oxides from the surface of parts being soldered, serve to protect metal and solder surfaces from oxidation, and ensure good wetting of the surface of parts with liquid solder.

For example, tip is made of copper, which oxidizes when heated, and a carbon crust forms on the working surface of the tip. If you touch the solder with such a tip, it will naturally melt, but it will not remain on the working surface, but will simply roll off, so you will not be able to solder anything with such a soldering iron.

The most common and affordable flux is rosin , which is made from pine resin. It looks like amber, transparent with a yellowish tint.

Preparing the soldering iron tip for soldering

And so, you bought a soldering kit. The first step is to prepare the soldering iron, namely its working part ( tip ), since it is not yet very suitable for soldering. We clamp it with pliers, take a file, and begin to carefully process the tip, giving it the shape of a dihedral angle of approximately 3045 degrees.

You have prepared the tip of the tip, but you cannot turn on the soldering iron yet, because when you turn it on for the first time, it emits smoke and an unpleasant odor, this is normal.
This happens because during the first heating, the adhesive layer with which the mica sheets were glued together when winding the heating element burns out.

Soldering iron heating element design

Let's look at the sectional design of the heating element.

The heating element in soldering irons is usually a nichrome wire wound around a metal tube into which a copper rod (tip) is inserted. The electric current heats up the nichrome wire, which in turn transfers heat to the copper rod, heating it.

To isolate this wire from contact with the protective casing and metal tube, mica is used, which is laid in layers between them.

Homemade soldering iron stand

Another thing you need, and you can’t live without it, is a soldering iron stand .
You can buy it there in the store, or you can make it yourself. It is enough to take a small wooden block and a metal lid used in home canning. You will put the remaining solder and flux in it, and also tin the leads of the parts and the soldering iron tip in it.

It is advisable to make a rectangular bath from the lid. Just be careful when you cut the lid, its edges are sharp as a blade, do all work with gloves.

So.
Cut a rectangle out of the lid with scissors, make markings with a marker, as in the picture, and bend the edges with pliers. When finished, be sure to file the edges of the bath and nail it to the block with two small nails. All. Your stand is ready.

Advice! Take electrical tape and tape the soldering iron wire to the handle as shown in the photo. This will save you from any surprises. Believe me!!!

Now you can turn on the soldering iron.
If you are indoors, then open the window, plug in the soldering iron and expose it to fresh air for 30-40 minutes. After this time, the product is ready for use.

Final preparation of the soldering iron tip. Service

As you noticed, the copper has turned dark blue, so we take a file and go over the working part of the tip, removing scale from it. Now quickly dip the tip into a jar of rosin and touch the solder to both sides.

Then, using small movements along the bottom of the bath, as if you were working with an eraser, move the tip back and forth, periodically dipping it in rosin for better wetting, until the working part is covered with solder on both sides.
Happened! The sting should always be this white .

Remember! The key to good soldering is a soldering iron tip that is free of oxides and well tinned. The solder should be a thin layer evenly distributed over the entire working surface of the tip .

Here you go. You have prepared the soldering iron for soldering, and now you can safely start practicing. In the second part of the article, how to properly solder with a soldering iron with rosin, you will learn how to tin and solder conductors together .
Good luck!

Nowadays, almost every person needs to be able to solder using a soldering iron with rosin. Since no repair of various electrical appliances can do without this. You can learn how to properly solder any object by reading this article.

• What should a soldering kit consist of?
• Work process
• Useful tips for beginners
• Safety precautions when working with a soldering iron

What should a soldering kit consist of?

In order to solder anything, you need to acquire the following tools: pliers, Phillips screwdrivers of various sizes, files, wire cutters, and, of course, the soldering iron itself, solder for soldering and flux.

There are many types of soldering iron , but their operating principle is the same for all, so choose the tool that you like best.

The best option for an inexperienced person would be an electric soldering iron operating on a 220-volt network with a power of 40 watts. In the future, as soon as you master all the intricacies of this work, you can purchase a power regulator for more complex work.

Solder is a metal alloy, which can be made of tin or lead, and is necessary in the soldering process, as it helps connect metal elements together. In the store it is sold as wire, but you can also buy solder in the form of a tube with rosin .

Flux is a product of processing wood resin. There are several types of flux, but the most common and effective for work is rosin flux . Help you get rid of acid on the soldering tool tip.

Work process

Before starting work, it is necessary to clean the surface of the soldering iron from acid. Since during previous work a film of oxidizing agents or other debris released during melting appeared on it, which will interfere with the work process.

To clean, you need to perform the following steps: heat up the soldering iron, then take sandpaper and use it to clean the tip . After this you can get to work.

Main stages:

1. To begin with, it is recommended to open the window in the room, since the room should be well ventilated so as not to harm your body during work.
2. Now plug the soldering iron into a power outlet. As soon as smoke stops coming from the tip, you can begin the soldering process.
3. Touch the tip of the soldering iron to the rosin, then wait a few minutes and tin the latches of the parts you need, to do this, just lean the soldering iron against them for a few seconds.
4. After this, place the soldering iron on the board. After ten seconds, you can repeat the process.
5. Once you've done a few passes, the job is complete, although if you need to solder copper wire, just one tinning is all it takes.
6. After tinning the copper wire, it must be coated with tin; to do this, touch the tip of the soldering iron to the tin alloy, and then transfer it to the wire. If you did everything correctly, the wire should change its color to silver.

Useful tips for beginners

• To achieve the most effective result, it is recommended to use solder with rosin. The best solder is considered to be tin in its pure form, but it has a significant drawback: it is too expensive. So, it is recommended to replace tin and use a lead-tin alloy as solder.
• During the melting process, the most important factor is the cleanliness of the joined surfaces from acid or other debris. So you need to do some cleaning before starting work; clean the surface as thoroughly as possible using a knife or sandpaper. As a result, the surface should become lighter.
• After this, it is also recommended to clean the surface with rosin.
• If you are soldering an object with a large surface and you do not have enough solder, then simply wait for the first part of the solder to cool, and then apply more nearby. The main thing is to ensure that the alloy is distributed evenly over the entire surface.
• There are times when you can solder something without using a soldering iron. To do this, you just need to take rosin and dissolve it in an alcohol solution, then apply it to the surface using tweezers or a screwdriver.

By the way, this method does not cause any harm to the human body, since no harmful substances are released during operation, unlike conventional soldering. So it’s up to you to choose the soldering method.

Safety precautions when working with a soldering iron

During work, solder and rosin, when certain temperatures are reached, will release various chemical elements that have an extremely negative effect on the human body, so it is necessary to work in a well-ventilated area, such a workplace will be able to reduce the content of harmful substances in the air.

Tin with rosin for soldering

In many situations, soldering requires great skill. Combining the functions of solders and flux mixtures in one product greatly simplifies the work.

There are several types of such products, each of which has its own characteristics - these are paste mixtures, ready-made solder with rosin, made in the form of wire, and tubular solder with flux. The choice is determined by the soldering mode, the nature of the part, and the requirements for the seam joint.

Wire with rosin

Combining two consumables in one product significantly simplifies the procedure and improves the efficiency and effectiveness of the work. If rosin as a flux is added separately, there is a high probability of adding an excess amount.

In the finished wire with flux, the ratio is fixed, stipulated by GOST.

Most often, products are supplied in a coil or coil. The version with wire packaging in coils is intended for continuous operation on an industrial scale. The assortment includes products of a wide variety of thicknesses.

Products in the form of coils are used for slightly smaller scales of use.

This option is suitable for both individual craftsmen and repair businesses. The thickness of the wire packaged in coils varies from 0.8 mm to the maximum possible 2 mm.

The solder component is an alloy of 2/5 parts lead and 3/5 parts tin. Each solder granule is surrounded by rosin, the total concentration of which varies from 0.8% to 1.2%.

The convenience of the wire is due to its flexibility . When soldering, such a mixture can be easily introduced into any gap, where it will melt and provide good envelopment of the parts and the formation of a strong seam.

The disadvantage is the low melting point of the mixture . Parts made from refractory alloys cannot be soldered with such consumables.

Working with solder wire containing rosin flux is similar to standard soldering. First, the parts need to be cleaned, then heated to the required temperature and consumables introduced into the work area.

Tube arrangement

The use of materials with dual functions in the form of tubes is economically and technologically beneficial. Consumption is reduced by almost 40%, and there is no need to remove the remaining flux after soldering.

Tubular solder contains 1, 3 or 5 internal channels into which flux is placed. There are several advantages of using this type of consumables:

• simultaneous supply of two trains to the working area;
• improvement of the final result;
• increase in work speed;
• simplification of soldering in hard-to-reach areas;
• reducing losses of funds;
• possibility of strict dosing;
• eliminating the possibility of dirt getting into the flux.

Tubes with one internal cavity can make soldering a little more difficult due to the rapid flow of flux into the work area. When working with multichannel solders containing flux, such troubles are unlikely.

In any case, you need to get used to using tubular products and learn how to properly regulate the solder supply speed. In general, the flow of flux through several channels minimizes the likelihood of disruption of the soldering technology.

Dry work will be completely eliminated. The flux enters the work area evenly through several channels, which leads to improved joint quality.

Solder material composition

The tubes contain both traditional and special solders.

As a solder mass for many metals and alloys, in particular for copper, a common alloy of tin and lead with eutectic properties is used.

The ratio of metals may vary to some extent. Recommendations for the use of such tubes correspond to the instructions for the use of homogeneous solders made of tin and lead.

For surface mounting work, it is better to choose products with a diameter from 0.46 to 1 mm. To solder miniature parts, flux solders containing silver additives are produced. The maximum melting point of the product is 188℃. The diameter of such tubes is 0.46 mm and 0.56 mm.

Solders with tin and copper have higher melting points, reaching 227℃. the tin content in them varies. Tubes are produced with fluxes in which the tin concentration is 95.5% and 99%. Some types of products contain silver additives.

For soldering elements of aluminum lamps, special solders with fluxes containing 80% lead, 18% tin and about 2% silver are supplied. Slight variation in the ratio of components allows you to expand the range of melting temperatures. The minimum is 178, the maximum is 270 ℃.

In most cases, the tubes contain purified rosin as fluxes. Strict dosing almost completely eliminates the possibility of residue formation. If any are discovered after finishing work, they do not need to be deleted.

When choosing consumables, you should pay attention to the manufacturer's information. The technology for producing solders with flux is quite simple, which increases the likelihood of counterfeits.

In low-quality products, the ratio of external and internal components may be disrupted. In professional production, the flux content usually varies from 1% to 4% of the total weight of the tube.

  Soldering an aluminum engine cooling radiator

Tips for use

To work with tubular consumables, you can take any soldering iron. It is important that its shape and dimensions provide the required contact with the parts.

If necessary, the tip should be cleaned by tinning using tubular solder with flux. If there is a lot of dirt on the sting, you should first treat it with a special sponge.

To be completely sure that the working part of the soldering iron is clean, you can use special paste-like products.

Do not allow the work area to overheat. To do this, it is important to monitor both the heating temperature of the soldering iron and the duration of soldering.

Soldering printed circuit boards requires special attention. The work area must first be thoroughly cleaned. You can buy specially designed solvents for this.

Each procedure for soldering parts on the board should last no more than 2 s. During this time, one connection must be made. If more time is spent, the wetting capabilities of the fluxes may not be enough. As a result, the strength of the connection between the electronic components and the board will deteriorate.

Handling tubing containing solder and flux takes some getting used to. The end result and convenience in subsequent work justify minor difficulties at the beginning.

Basic principles and rules for soldering work

In order to understand and find out how to properly use a soldering iron for soldering wires, you need to have a minimum set of tools:

• Soldering iron, preferably electric from the main power source of 220 volts.
• Tin or other interchangeable solders.
• Rosin.

The power of the soldering iron should be no more than 40 watts, the standard power supply is 220 volts. For domestic use, this power of the device is quite enough. Ready-made solder is needed for high-quality connection of parts and assemblies.

  As the main components of solder we use tin with lead components, as well as traditional rosin. The retail network sells ready-made tubes with a compound inside or special wire.

The latter option is recognized as the most effective and best in many performance parameters.

Characteristics of solder and rosin

Next, we’ll figure out how to properly solder wires with a soldering iron with rosin and tin when choosing the required brand of solder. In this case, the PIC marking, the so-called tin-lead solder, is suitable. The marking contains digital values, so 60 is the percentage of tin, and 40% is the lead content.

  You can find solders on the market that have a high lead content. This material has the best characteristics that ensure high quality work when connecting parts.

  The composition differs in color, the melting temperature will be an order of magnitude higher than with conventional series and PIC markings, but the quality of the processing site will also be high.

Tin-lead solder

Rosin plays an important role in this process, which allows you to solve not only the problem of how to properly solder wires with a soldering iron, but also helps to achieve the necessary strength of the connection. The main purpose of rosin is to remove oxides from processed soldered parts. The use of rosin is mandatory, since the copper tip, when heated, forms a specific carbon deposit that interferes with the quality of ensuring the strength of the connection of parts on the microcircuit.
