Classification specifications and functions of solder wire and solder wire

Solder Wire Specification Classification,Depending on the situation, there are several ways to classify solder filaments:

According to metal alloy materials to classify: 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 alloy material solder wire;

According to the chemical composition of solder wire additives to classify: can be divided into rosin core solder wire, no cleaning solder wire, solid core solder wire, weight lipid solder wire, single-core solder wire, three-core solder wire, water-soluble solder wire, aluminum solder wire, stainless steel solder wire;

According to the melting temperature classification: Can be divided into low-temperature solder wire, normal temperature solder wire, high-temperature solder wire.

Solder Wire Action:Manual electronic original device welding using solder wire, is composed of tin alloy and additives two parts, in electronic welding, solder wire and soldering iron, high-quality soldering iron to provide stable and continuous melting heat, solder wire as a filler metal added to the surface and gap of the electronic original device, fixed electronic components become the main component of welding, The composition of solder wire is closely related to the quality of solder wire, which will affect the chemical properties, mechanical properties and physical properties of solder wire.

Solder wire without Auxiliaries is not capable of welding electronic originals because it does not have wettability and extensibility. and the welding will produce splash, solder joint formation is not good, long time to develop the performance of additives affect the performance of solder wire welding.
