PRO/Strip 2100S Special is the first step of a two-step nitric acid-based tin and tin-lead stripping solution designed specifically for dual tank dip applications. PRO/Strip 2100S Special is designed to remove 80% – 95% of the tin or tin/lead etch resist, leaving only the copper-tin intermetallic layer to be stripped in the second step, using PRO/Strip 2101-B.
