Type 6 solder paste with water soluble flux

NP303-WS4070-T6 solder paste

GENMA solder paste – our NP303-WS6157-T6 solder paste with water soluble flux. It convinces with its outstanding printability, highly precise contours, long open time, and consistent adhesiveness in the pick-and-place process. Its extremely good wetting properties, also on difficult surfaces, produce perfect soldering joints on BGAs.

Hardly any voids in the solder connections. Cleaning of flux residues with water after soldering is required. The solder paste can be soldered under nitrogen reflow.
