How to solder with a soldering iron with rosin
My relationship with radio and microelectronics dates back to childhood. From an early age I was interested in soldering, and I already have enough experience behind me to share it with readers.
Many beginners who want to play with microcircuits, when approaching the matter, begin to feel intimidated by such a wide range of possibilities, and do not know where to start. You can start with the simplest breadboards, this will help you understand the general features and get a little familiar with such an interesting art. After some shenanigans with breadboards, you can start moving to a simple circuit board without tracks (an example is the GMC-4).
For many people, the soldering process involves the following plan: plug the soldering iron into a socket, wait for the soldering iron to heat up, dip the tip in rosin, bring it to the soldering area and magically everything works out, but this is far from real soldering.
If you use the above soldering plan, then while you are carrying the soldering iron to the soldering site, all the rosin that you rolled onto the tip of the soldering iron will almost completely burn out and not only will the soldering site be of poor quality, it may not work out at all. At the very beginning of my acquaintance with the craft of soldering, I did much the same without understanding at all how to do it correctly.
My father came to the rescue, and thanks to his advice, I learned the basics of soldering, everything else was learned as the range of work increased, and at the moment I can share my accumulated experience with you.
What is rosin used for?
In many life situations when high-quality and fast soldering is required, it would be most advisable to use rosin for soldering. It was with her that I began my immersion in this art.
Many who started soldering used rosin for soldering, but no one thought about what rosin is and what useful qualities it has.
The starting raw material from which rosin is produced is the most common pine resin, which, in addition to rosin, contains various vapors in the resin composition.
The entire manufacturing process is very simple: turpentine fumes are evaporated from raw resin using various technologies, and the output is a material ready for soldering. Rosin is easy to use and very pliable, making it ideal for beginners to get used to the soldering process.
If you need simple soldering of copper parts, then rosin will do the trick. Due to its low cost, it is a convenient material.
Soldering process with rosin
Rosin is sold both pure and in the form of liquid or viscous fluxes. The price for one kilogram of solid rosin is 400-500 rubles. And so let's begin the soldering process. To ensure everything works out and the joint turns out strong, follow these instructions.
Firstly, as in any other work, we need to prepare our working tool, in our case it is a soldering iron, we need to heat it up, and also clean the tip and cover it with a thin layer of solder.
The next step is to put a small amount of rosin on the tip and immediately connect it to the solder. It is possible that the solder will not stick to the tip, in which case you will need to take a natural board and apply the soldering iron tip to it for a short time, then repeat this several times. This way we will achieve the result we need to work.
Wire soldering process
In order to solder two wires together, first we need to tin the wires, from the insulating layer, at this point the main thing is not to overdo it and clean off exactly as much space as is required for soldering (If you clean off more, it’s okay to shorten the wire).
After you have tinned the wires, we lower part of the wire into rosin and press it with the tip of the soldering iron, then immediately, without lifting the wire from the rosin, we connect it to the second one, after which all we have to do is cover the joint with tin.
(You can check the quality of the work done by color; if the soldering area turns silver, then the solder is considered correct.)
Soldering process of copper part
Often we need to solder a wire to some copper part and connect the contacts. Now we will look at how to do this. To begin with, just like for soldering with wire, we need to prepare our tool, as you can see above how to do this.
Let's move on to the soldering process, first we need to apply a rosin-tin mixture to the tip of the tip and rub it at the place where the solder will occur. Tinning will be correct if the color is silver. The next step is to put a little bit of iron on the tip of the soldering iron tip and connect the wire to the place that has been tinned.
After soldering the wire to the copper part, you need to let the soldering area cool completely and check the quality of the soldering without sudden movements.
Features of soldering with rosin
As with any activity, soldering has its own peculiarities and tricks to ensure the job goes off without a hitch.
Firstly, this is tinning. The quality of tinning is your quality of soldering; without proper tinning, there will be no normal soldering. So, don’t be lazy and tin it properly before soldering.
Secondly, prepare as much surface as you need for soldering; do not overdo it with the place for soldering; soldering is a delicate art that loves precision. After all, the result of the entire process depends on proper preparation. So, if you don't get the tin right the first time, instead of continuing with the damaged material, you should get a new one and try again.
Thirdly, it happens that while soldering you do not have enough flux, in this case the correct decision would be to leave the soldering to cool and not continue to grind, it would be better to take the missing amount of flux and continue soldering than to ruin the workpiece completely.

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.

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.

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.
