ALPHA® SnCX Plus™ 07 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.
As with all Alpha Metals bar solder, Alpha’s proprietary Vaculoy™ manufacturing process is used to remove certain impurities, particularly oxides. The product is further enhanced with the addition of other elements designed to further improve alloy physical and mechanical properties, reduce drossing, increase wetting speed and force and improve joint reliability.
