Andrew, could you be a little more specific on what you mean by holes
in the solder mask? I am not sure what you are trying to describe. Is the
solder mask peeling or is the surface attacked?

We just got a batch of boards back from our assembler today with holes
in
the soldermask.  The mask used was Taiyo Green LPI.  Our assembler
has
recently started using a no-clean process, and I'm wondering if that
might
have had an effect on the soldermask and caused it to weaken... either
that
or the boards just got a bad batch of mask to begin with.  Anyone have
any
ideas?
