Hello again...

Looking for suggestions for removing masking material (tape or liquid) which
is applied to mask areas from conformal coating.  The way we do it now, the
operator masks off the area (usually tape), sprays the board, cures the
coating, scores the coating around the tape, then removes the tape.  We're
trying to eliminate the scoring of the coating since this has potential of
cutting through traces.  Removal of the coating prior to curing doesn't work
because the coating runs during the heat cure process.  I'm trying to avoid
room temperature cure since this is very time consuming.  Ant suggestions?
