How to solder with rosin correctly

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

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 and rosin

Any novice specialist involved in the maintenance and repair of radio electronics is faced with the need to buy a device designed for high-quality work on connecting damaged sections of the microcircuit. Let's try to figure out how to solder correctly with a soldering iron with rosin, what a novice specialist and a master with a wealth of knowledge needs to know.

Soldering using rosin

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.

How to use rosin when soldering - Metalworker's Handbook

Knowing how to solder with a soldering iron is very useful in everyday life. There are a number of techniques on how to do this, but it is best to master the theoretical part before starting the work process.

Peculiarities

There are many ways to learn how to solder with a soldering iron from scratch. To do this, you will need a soldering iron - a device designed to heat parts or flux during tinning and soldering.

The tool is brought to the area where the parts are soldered, touching them with the so-called tip. The tip is the working part of the tool, which is heated using a blowtorch or electricity.

Rosin is most often used for soldering, but to work with this material you need to know how to properly solder with a soldering iron with rosin.

Before soldering, you need to perform a number of actions:

1. First of all, remove any dirt from the surface.
   To do this, use sandpaper. Degrease the desired area with gasoline or acetone.
2. After warming up the instrument, its end is covered with rosin. The next step is tinning. The solder must be ground using a wooden block. After the procedure, the surface acquires a silver tint.
3. Next, the solder is heated until the optimum temperature is reached.

   The tip heating rate should be 20–40 degrees higher than the soldering temperature.

4. The brush is moistened with alcohol, then excess rosin is removed with it.
5. Soldering must be done at one time; if the number of procedures is increased, this will negatively affect the quality of the work performed. The solder will turn gray (as oxidation occurs). When touched with a sting, the parts are fixed to create a strong connection without microcracks.
6. For better soldering, flux is used, a special liquid that helps clean the surface before soldering. It is the substance with which you can remove oxides from the solder surface. Thanks to its use, liquid solder spreads better, in an even layer. Do not overheat the soldering iron, as this will cause the flux to burn and become charred.

If you're working with a metal like aluminum, it's worth knowing its characteristics. The melting point of aluminum is 660.1 degrees.

A small amount is applied to the joint area and then leveled. The contact point must be covered.

The working process

A kind of connector between two components is called soldering. Its main role is to create a sufficiently strong connection.

Solder is a metal alloy that can be divided into two large groups. Soft solders have a melting point of up to 300 degrees; this type is used in electronics.

The next type of solder is the hard group, in which the melting point exceeds 300 degrees. This type is actively used for reliable joining of metals.

The soldering sequence is as follows:

• the surface is first cleaned of corrosion or any other type of contamination;
• the next step is complete cleansing until it acquires its characteristic shine. Traces of oxides should not be visible;
• For coating, flux is used, which removes oxide residues and minimizes the appearance of surface oxidation. The best choice in this case is flux paste. Liquid or solid fluxes are not suitable;
• the master carries out tinning. Solder is applied to a certain area of ​​the surface in molten form, after which it spreads evenly;
• using twisting and compression with tweezers or a clamp, the main parts are connected;
• The flux application procedure is repeated. This is necessary to minimize the risk of solder oxidation under high temperature;
• Solder is applied along with heating;
• It is also important to note that when using a tool with a tinned tip, it must be cleaned using inactive flux. The soldering iron must be stored with a fluxed tip. This affects the quality of further work.

Cleaning

The procedure for cleaning the soldering iron tip is carried out by rubbing it against a soft porous or fibrous lining. The best option would be to choose natural felt. An alternative would be to use basalt cardboard. Two-stage cleaning is considered high-quality. The first step concerns the use of a sponge-tangle made of metal tape.

The second stage of cleaning involves the use of felt.

At the end the instrument is turned off. The stage when the master inserts a hot sting into solid rosin is considered important. You need to wait until it stops blowing bubbles. After this, the master removes the sting, holding it with the end down. This way, the excess rosin will drain off. Once the instrument has cooled completely, it can be stored.

Pipe soldering

Based on the technological features of this procedure, the masters use the following stages of action:

• First of all, you need to prepare the tool. We are talking about heating it to the optimal temperature. The temperature in the room is also important. After all, if the weather is hot, then the time is reduced. During the cold season, for example, the duration of soldering increases.
• The next stage concerns the preparation of the pipe. Use a pipe cutter to cut the pipe at a right angle. You can replace the tool with special scissors. The cut area should be cleaned and then degreased.
• Parts must be dry.
• The next step concerns soldering. The elements are thus connected securely to each other. After completing the procedure, you must wait until the parts cool down.

You can perform the procedure yourself. If you are unable to complete the procedure, then it is best to use the services of a specialist. It is best to solder the first element first. It is necessary to cool and cut the part in order to check the quality of workmanship.

If there are errors, this will be noticeable. During installation work or during pipeline repairs, this skill will come in handy.

Soldering wires

The most common question concerns how to solder correctly with a soldering iron. First, you need to free the ends of the wires from the insulation using a knife or wire cutters. The parameters of the cores must correspond to the dimensions of the parts. It is best when the soldering iron is not too large, then adjacent areas will not be damaged in the process. A small soldering iron, by comparison, achieves unreliable, low-quality results. It is quite difficult to warm up parts with it.

If you are soldering stranded wire, then you need to twist it, then tin it. The procedure is as follows. The wire is dipped into a bath of rosin. The craftsman runs a drop of solder across the surface of the copper wires. The coating should be even, covering all sides. Excess rosin is removed.

Solder is classified as a weak alloy. It is characterized by low reliability, because it is damaged under the influence of small loads. In the process, rosin is applied to the wires, followed by solder. The heating time for the twist is 2–3 seconds.

If we are talking about single-core wires, then they are first cleaned until they acquire a shine, then dipped in rosin. The connection takes approximately 3–5 seconds. Then a large-diameter heat-shrinkable tube is placed over the exposed wire. Following this procedure will ensure a high level of insulation.

Experts recommend using an ordinary lighter when cooling quickly.

Soldering

When asking a question about how to properly solder microchips with a soldering iron, it is better to entrust such work to a specialist. After all, the work itself is quite scrupulous and requires experience and a certain skill.

For proper soldering, it is necessary to take time to prepare the parts needed in the tooling process. Familiarize yourself with the theoretical aspect, and then consolidate your knowledge in practice.

It is necessary to remember to protect the layer of molten solder with flux. The operation you perform also matters. Based on this, you need to select a device of appropriate power and with a suitable tip shape.

By following the basic rules for using the device and the recommendations of specialists, you will be able to connect the parts in the correct way, thanks to which the soldering will last a really long time. Similar: Electrical wiring in the kitchen: installation rules and diagram

How to use rosin when soldering?

Hello dear readers of the site sesaga.ru. Today I want to share with you the secret of good soldering, and tell you how to solder correctly with a soldering iron .

Every radio amateur has a minimum set of tools that he needs to assemble or repair any radio-electronic structure.
These are all kinds of screwdrivers, pliers, wire cutters, files, hammers, etc. Therefore, I will not recommend anything here, but will focus on the most basic ones. In the future, if you need an additional tool, you will purchase it.

The first thing you need to purchase, if you don’t have one, is tweezers and a soldering kit:

1. Soldering iron ,
2. Solder (tin) ,
3. Flux (a jar of rosin) .

soldering iron with a power of 40W and a supply voltage of 220V. At home, you don’t need any other power; when you learn to solder, you’ll understand this. And when we assemble a power regulator for it that adjusts the temperature of the tip, it will become more convenient and versatile.

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!

How to solder correctly with a soldering iron and rosin? — Metals, equipment, instructions

instrument.guru > Welding > How to properly solder with a soldering iron using rosin

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 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.

Soldering is popular when assembling various electrical and radio devices. It provides electrically conductive connections of copper wires and other copper products to each other, to electrical circuit components and other metal parts made of pure copper and copper alloys, as well as to solder aluminum. Soldering is simple, very flexible, and allows for low contact resistance of the components being connected.

The essence of soldering technology is to heat the contact zone and then fill it with liquid metal low-melting solder. After cooling, the melt provides electrical contact. Before soldering the wires, additional processing of the surfaces to be connected is usually necessary (most often the so-called tinning of the wires), which guarantees long-term stability.

In the absence of vibrations and shock loads for small parts, good connection strength is achieved. In all other cases, solder with additional fixation.

What might you need for soldering?

Soldering requires a heat source. You can solder using an open flame, an electric spiral, or a laser beam. The latter allows you to solder even with pure metal. At home they mostly use an electric soldering iron. It is intended for:

• installation and repair of various electronic circuits;
• design and repair of electrical equipment;
• tinning a layer of solder on various metal products.

Soldering iron

Solder with a hand soldering iron, which is used for:

• warming up the connected components;
• heating the solder until it turns into a liquid state;
• applying liquid solder to the elements to be connected.

The soldering iron, which is shown in Figure 1, contains:

• a spiral heater made of nichrome wire insulated with mica film or fiberglass;
• copper tip, which is located inside the spiral;
• plastic or wooden handle;
• housing for placing a soldering iron tip and spiral.

Figure 1. 100-watt soldering iron with plastic handle and three-pole plug

Connection to the electrical network is made with a cable approximately 1 m long, which exits from the rear of the handle through a bending radius limiter.

The wooden or plastic handle is shaped like a simple handle. Electronic circuits are soldered with low-power products equipped with pistol grips with a trigger button for quickly heating the tip. One version of such a tool is shown in Figure 2.

Figure 2. Pistol type radio soldering iron

Household soldering irons are designed for connection to a network with voltages of 12 and 220 V.

For reasons of electrical safety, 220-volt soldering irons must be equipped with a 3-pin plug that provides reliable grounding. For 12-volt equipment, a simple 2-pin flat plug is sufficient.

Solder pastes

Solder paste is a composition of solder and flux. It is used for soldering in hard-to-reach places, as well as when installing leadless electronic elements. The composition is applied to the component, which is then simply heated with a sting.

You can make your own pasta. To do this, tin filings are mixed with liquid flux to a gel-like consistency. The paste is stored in an airtight container; the shelf life due to tin oxidation does not exceed six months.

Soldering iron stand

They solder with a tip heated to a high temperature, so during breaks the tool is left on the stand. For powerful soldering irons, it is made with two supports: the back one for the handle, the front one for the body. The supports are mounted on a plywood base, which is used for:

• installing a box of rosin;
• storage of solder wire (an example is shown in Figure 3);
• cleaning the tip.

Figure 3 shows that the stand does not require scarce materials and can be made by hand.

Figure 3. Homemade stand for a powerful soldering iron

For low-power devices, a cone-shaped holder (regular or spiral, which is also shown in Figure 3) is often used, into which the tool is inserted with a tip.

Older models of stands are equipped with an operating temperature regulator and an LCD display for indicating the temperature of the tip, Figure 4. Such a soldering tool is often called a soldering station.

Solder Removal Braid

They are soldered with braiding in cases where it is necessary to remove solder from a printed circuit board when dismantling parts. It is a dense mesh of thin copper wires coated with flux.

The principle of operation is based on the surface effect: the mesh “absorbs” solder melted on the printed circuit board due to capillary forces.

Typically the width of the braid is about 5 mm, supplied in rolls in a casing with a diameter of approximately 5 cm.

The outer braid of an old flexible coaxial cable can perform the desoldering function.

Security measures

Compliance with safety precautions:

• helps protect against thermal burns;
• prevents fire;
• protects against electric shock.

Before you start soldering, you should make sure that the power cable is in good condition. The sting should not touch the reins or other objects. The soldering iron must always be placed on a stand. It is forbidden to touch its body; you can only take the tool by the handle.

Work place

Soldering is always done under normal general lighting (no worse than 500 lux); if it is necessary to create more comfortable conditions, a local lighting source is used.

Good ventilation should be ensured. The best results are obtained by a hood; in its absence, solder intermittently to ventilate the room from rosin vapors (every hour during intensive work).

How to solder correctly with a soldering iron with rosin: instructions and recommendations

remontoni.guru > Tools and equipment > How to solder correctly with a soldering iron with rosin: instructions and recommendations

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.

You can also harm yourself when using a soldering iron from a low-quality outlet . Therefore, before starting work, it is recommended to make sure that your workplace will be as safe as possible and that the outlet is in working order.

If you do not operate it correctly, you may experience a fire, since the soldering iron has a high temperature when heated. To prevent this from happening, use special soldering iron stands that will not catch fire from high temperatures.

After reading this article, you know what rosin, flux and solder are, and now you are familiar with the main points of working with a soldering iron. So you can start repairing electrical household appliances yourself using a soldering iron, most importantly, do not forget to follow the tips described in the article, and you will succeed.
