Vince,
Is this before or after cure? I've had some bad experience with
stripping soldermask after being cured, especially batched stripped
versus in-line spray method. Worse case scenario, conductors lifting
from laminate, expecially in isolated areas. This was two years ago,
so what has changed? I currently have a situation with a vendor where
the soldermask is very thick, color is not to spec (no biggy) and
slightly mis-registered (S/M runs on to lands). Our wireless group
forwarded the PCB's back to the vendor to have the soldermask
stripped. I was furious when I found this out, due to past
experiences. Should I still be catious or has soldermask stripping
tremendously improved.

Sorry for the delay, I have been out of town for two weeks. Coates uses
OS-953 Soldermask Remover in their Arizona facility & recommends the
material to their customers.
