Happy Friday...and in Northern Ohio USA- welcome Mr. or Mrs. Sun!!
We have just practiced processing .014 Pyralux pc bds.  All went well until
we had to solder mask the boards.  We use a hand screened thermal cured mask.
 The boards are impossible because of warp factor.  Does anyone out there
know of  a screening table with a vacuum to hold the boards in place for hand
screening?
Thanks.
Mike
