No-clean lead solder wire

Explain

No-clean solder wire is a kind of halogen-free reactive resin soft soldering tin wire, a single core, three core, five core, is designed for electronic industry no-clean soldering process matching use.

Characteristic

· resin with special active agent can provide fast wetting

· minimum residue core solder

· can meet the special requirements of high reliability and high stability in the process of welding disposable

The mirrors corrosion test strictly

· surface insulation resistance value
