Informations of solder wire

Our production of a variety of series alloy lead-free solder wire, in addition to the corresponding alloy welding performance and physical properties, solder wire also has the following advantages:

High performance flux, melting rate, good mobility, speed on the tin.

Lower flux when welding spatter rate.

Flux distribution, good continuity.

Minimal smoke and  gas.

Inhibition of the solder joint cracking, copper corrosion and the growth of the interface and the metal.

Low residue, no corrosion, high insulation resistance, no-clean solder wire
