SS-A/B Solder Stripper is specifically designed for solder and tin stripping applications. SS-A is to be used in conjunction with SS-B for the first part in a two stage solder stripper. The two parts of this stripper are separate to maximize stability and ensure a long shelf life. It contains no complex fluorides thus avoiding the possibility of solution exotherming, and will not attack laminate. SS-A/B strips rapidly and stops at the intermetallic layer between the solder and copper therefore allowing the board to remain in the stripping solution without being damaged. The intermetallic layer is removed quickly using SS2 copper conditioner or EZ 6001 Solder stripper.
