Alpha Bar SnCX Plus 07 Solder Alloy is No-silver lead-free alloy suitable for use as a replacement for SnPb, SAC305 and other low silver SAC alloys in wave solder, selective soldering, lead tinning and rework processes. SnCX Plus 07 has been engineered to minimize copper dissolution as compared to silver-bearing alloys and also to improve total cost of ownership. The SnCX Plus 00 variant is used as a replenishment alloy in solder baths with elevated copper levels.
