Flux cored solder wire
Water soluble type WSG series
Good wettability
Apply flux activator according to base material.Good solderbility can achieve higher productivity for various type parts.
Good wettability
●Wettability comparison in line soldering
Sustained wettability

Reduce spattering
With the effect of special activator, solder and flux spattering were reduced.Higher mounting quality can be secured.
Very few spattering
●Flux spattering test with soldering iron robot
Few spattering
-
Collect spattered flux onto thermal paper.
