Solder Mask Check Wipes seek out under-cured and porous solder resist. Can help identify conductive residues from HASL fluids causing electromigration or poor SIR values. Provides immediate color observation after 10 to 15 sec. of wiping bare or populated printed circuit boards. Can be used to pre-wipe bare PCBs to remove bleed from solder resist onto surface mount pads.
