According to different situations,
solder wire has several classification methods:
Classified by metal alloy material: can be divided into tin-lead alloy solder 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 tin-containing alloy material of solder wire;
Classified by melting temperature: can be divided into low temperature solder wire, normal temperature solder wire, high temperature solder wire.
The role of solder wire
The solder wire used for manual electronic component welding is composed of tin alloy and additives. The high-quality electric soldering iron provides stable and continuous melting heat, and the solder wire is used as a filler. The metal is added to the surface and gap of the electronic component, and the fixed electronic component becomes the main component of welding.
[1] Solder with lower melting point. Mainly refers to the solder made of tin-based alloys. Melting method ingot, pressure processing into material.
Solder materials are indispensable in the production and maintenance of the electronics industry. Generally speaking, commonly used solder materials include tin-lead alloy solder, antimony solder, cadmium solder, silver solder, and copper solder.
[2] The wire-shaped solder used in standard soldering operations is called rosin-cored solder wire or solder wire. Flux is added to the solder.
