I am looking for a  printable peelable mask which can withstand three
thermal cycles. The mask can be no more than 3 mils thick when cured.  All
of the ones that I tried worked well with two thermal cycles. But when they
were exposed to three, either they became to difficult to remove, showed
evidence of cracking, or stained the board.

Thanks
Mike Yuen
