The first secret of soldering

It is necessary to use the right flux and solder for soldering. A solder is a metallic, fusible alloy that bonds the leads and wires together. The best solder is pure tin. Because it is expensive, it is rarely used. A common soldering method used in radio wiring is tin-lead solder, which is an alloy of lead and tin. Such solder is as strong as pure tin. It melts at 180-200°C and is labeled PIC, and the two-digit number behind it indicates the percentage of tin. Flux is an antioxidant. It is used to prepare conductors and parts before soldering, so that they do not oxidize during soldering. Without flux, the solder will not adhere well to the metal surface.

The second secret

It lies in the cleanliness of the soldering iron tip, as well as in the correct heating mode. If the tip is dirty, it will be difficult to work - the solder will melt, but will not adhere to the surface. It is necessary to tin and deburr the nib, i.e. to cover it with the thinnest layer of solder. To do this, you need to heat the soldering iron and grind its sting with an emery cloth or file. Then you need to dip it in rosin, and then touch the sting to the piece of solder.

The third secret

The soldering surface must be clean. Places of parts and conductors prepared for soldering should be well deburred. A well-cleaned part should be placed on a piece of rosin and heated well with a soldering iron. The rosin will melt quickly and the solder on the soldering iron will spread evenly over the conductor.

The fourth secret

When soldering, the solder should be evenly distributed on the surface of the conductor. This is done by turning the conductor and slowly moving the sting on it. If you are soldering tinned two conductors, you must press them tightly together and put the soldering iron to the point of contact. The solder will spread after heating, filling all the gaps between the conductors. The soldering time should not exceed five seconds, the solder will harden quickly, holding the parts firmly together.

N.B.

Keep in mind that harmful lead and tin fumes are released during soldering. Do not bend over or inhale the fumes above the soldering point. At the end of the work it is necessary to wash your hands with water and soap and do not forget to ventilate the room during work.
