The Influence of Surface Active Agent on Zn Base Brazing Filler Metal Soft Solder

The wetting property of Zinc base solder was difficult, so surface active agent could improve the wettability. This paper studied the impact of surfactant OP - 10 to Zn20Sn solder soft solder physical properties and spreading performance, the results show that: when the surfactant OP - 10 content is 1 wt.%, the non-stick, corrosive, non-volatile content and stability of soft solder all meet the national standards and spreading performance is good.
