Solder wire, Chinese Name: solder wire, solder wire, tin wire, tin wire, English Name: solder wire, solder wire is tin alloy and additives is composed of two parts, alloy composition points for tin lead and lead-free additives homogeneous perfusion to the middle part of the tin alloy.

Solder wire with different kinds of additives is different, the auxiliary part is raising solder wire in welding process of auxiliary heat conduction, removal of the oxide, reduce the surface tension of the material to be welded, removed welding material surface oil, increase the welding area. Characteristics of the solder wire is with a certain length and diameter of tin alloy wire in electronic components welding can be with the electric soldering iron or laser with use.
