Описание товара







Name: Advanced rosin
Brand: JJS
Product description:
1. This product is used for welding of 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 by 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.
Flux has three major functions
1. Remove the oxide film. The essence is that the substance in the flux undergoes a reduction reaction, thereby removing the oxide film, and the reaction product becomes suspended slag and floats on the surface of the solder.
2. Prevent oxidation. After it melts, it floats on the surface of the solder to form an isolation layer, thereby preventing variations in the soldered surface.
3. Reduce the tension of the surface. Increase solder flow and help solder wet weldments.
