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
