How to choose a tin wire for an automatic soldering machine?

Summary of Automatic Soldering Machine: 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 type of solder wire is different, and the additives will also be different. 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 a tin alloy wire with a certain length and diameter, which can be used in conjunction with an electric soldering iron in the welding of electronic components.

According to different situations, there are several classification methods for the solder wire of automatic soldering machines, including metal alloy materials, chemical composition of additives, melting temperature of solder wire, and diameter of solder wire

Classified by metal alloy materials: 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 solder wire

According to the chemical composition of the additives used in soldering wire, it can be classified into rosin core soldering wire, non cleaning soldering wire, solid core soldering wire, weight grease type soldering wire, single core soldering wire, three core soldering wire, water-soluble soldering wire, aluminum soldering wire, and stainless steel soldering wire

Classified by melting temperature: it can be divided into low-temperature soldering wire, room temperature soldering wire, and high-temperature soldering wire.
