There are many varieties of tin alloys. For example, solders of the PIC brand consist of a tin base with the addition of lead and other elements. Other fusible alloys are also made on the basis of tin. For example, Rose and Wood alloys known to the world of electronics, All tin solders are in high demand due to their main qualities - easy melting and corrosion resistance.

Soldering Technology
To get the best result when using tin solder, the technological process of soldering must necessarily consist of the following operations:
- chemical or mechanical cleaning (file, scraper or sandpaper) cleaning;
- Coating with flux;
- Heating (soldering lamp, blowtorch, horn)
- Pre-tinning with solder (by rubbing with a soldering iron, immersion in solder)
- bonding of all the soldering points, covering them with flux and heating them properly;
- introducing the solder itself, performing its melting and removing all the excess solder, together with the rest of the flux.
Cleaning
Oxide deposits on soldered surfaces should be cleaned by files or doctors, so that the space between the two surfaces is always equal, and does not exceed 0.1-0.3 mm. This small gap is very necessary for the formation of capillary forces, which will contribute to the suction of solder to the maximum depth from the edge. If the surfaces to be soldered are contaminated with traces of grease or oil, they should be treated with a hot alkali solution. A 10% soda solution is usually used for this purpose.
After a complete cleaning and preparation of the soldering point, all parts must be tinned. In this case increased strength and tightness of solder will be achieved.
