Product Description:
1. This product is used for welding general instruments, instruments, copper tin and iron, etc. It is very helpful for the welding of circuit boards. When the surface of the soldering iron or component is oxidized, it is not easy to solder on the solder. After soldering with rosin Oxidation can be quickly removed, making the components extremely solderable.
2. Rosin is the oil flowing out from the inside of the pine trunk. It is melted into water at a high temperature. After drying, it becomes a massive solid (with no fixed melting point). Its color is yellowish and deep red. It is mainly used in the welding of electronic circuits. Mainly used to polish the strings of the instrument to make it play a role in the hair.
3. Since the metal surface is in contact with air, an oxide film is formed. The higher the temperature, the stronger the oxidation. This oxide film prevents the liquid solder from wetting the metal. Flux is a special material used to remove oxide film, also known as flux.
