Characteristics of low temperature solder wire:

1. Meet the environmental protection requirements of ROHS.

2. Good weldability, good wettability and good expansibility.

3. Low melting point, low welding temperature, reduce the thermal impact on components.

4. Rosin core or solid core (solid core needs to be used together with flux)

5. Suitable for welding of electronic components that cannot withstand high temperature.
The solder wire is composed of medium tin alloy and aid. The alloy composition is divided into tin lead, and the lead-free additive is evenly poured into the middle part of the tin alloy. There are several ways to classify solder wire according to different situations. According to the classification of metal alloy materials: can be divided into tin lead alloy coal tin wire, pure tin solder wire, tin copper alloy solder wire, tin silver copper alloy solder wire, tin bismuth alloy solder wire, tin nickel alloy solder wire and special bead tin life gold material solder wire. According to the chemical composition of the auxiliary agent of the solder wire, it can be classified into rosin core solder wire, non-cleaning solder wire, solid core solder wire, right grease type solder wire, single core solder wire, three-core solder wire, water-soluble solder wire, aluminum fire solder wire, stainless steel solder wire. Melting temperature meter classification: can be divided into low temperature solder wire, normal temperature solder wire, high temperature solder wire.
