Solder wire, Chinese name: solder wire, solder wire, tin wire, tin wire, English name: solder wire, solder wire is composed of two parts: tin alloy and additives. To the middle of the tin alloy. The solder wire is composed of a tin alloy and an auxiliary agent. The alloy composition is divided into a tin-lead and a lead-free auxiliary agent and uniformly poured into the middle part of the tin alloy. So what is the role of solder wire? The following is introduced by the editor of Shenzhen Xinghongtai solder wire manufacturer:
The role of tin wire:
The solder wire used for manual electronic component welding is composed of a tin alloy and an auxiliary agent. During electronic welding, the solder wire is combined with an electric soldering iron. A high-quality electric soldering iron provides stable and continuous melting heat. The solder wire is used as a filler. The metal is added to the surface and gap of the electronic device, and the fixed electronic device becomes the main component of the welding. The composition of the solder wire and the quality of the solder wire are inseparable, which will affect the chemical and mechanical properties and physical properties of the solder wire.
Solder wire without additives is not capable of soldering electronic components, because it does not have wettability and expandability. However, the welding process will produce spatters and the formation of solder joints is not good. The properties of the additives have been developed for a long time to affect the performance of the solder wire.
Different types of solder wire have different auxiliaries. The auxiliary part is to improve the auxiliary heat conduction of the solder wire during the welding process, remove oxidation, reduce the surface tension of the material being welded, remove the oil on the surface of the material being welded, and increase the welding area. The characteristic of the solder wire is a tin alloy wire with a certain length and diameter, which can be used in conjunction with an electric soldering iron or laser in the welding of electronic original devices.
