OS-993 Soldermask Remover
OS-993* Soldermask Remover is an aqueous, alkaline liquid designed to remove fully cured dry film soldermask and photoimageable soldermasks from printed circuit boards. OS-993* is very effective on some of the newer masks that are more difficult to strip. It can also completely remove soldermask without needing to mechanically scrub the boards following immersion in OS-993*. OS-993* removes soldermask with much shorter exposure time than most competitive products. Soldermask is removed without damaging the circuitry or epoxy laminate.
