[0002] Tin wire, also known as solder wire, is composed of tin alloy and additives. Different types of solder wires have different additives. The additive part is to improve the auxiliary heat conduction of the solder wire during the welding process, remove oxidation, reduce the surface tension of the welded material, remove oil stains on the surface of the welded material, and increase the welding area. The characteristic of solder wire is that it is a tin alloy wire with a certain length and diameter. It can be used with an electric soldering iron or laser in the welding of electronic components.
