resist film to test

2006-04-05 by David Griffith

I was wondering if I could get two or three people to test some
photoresist film for me.  I acquired a roll of Aqua Mer PR120 photoresist
film at an auction with the intent of parting it out in smaller quantities
to hobbyists on Ebay.  I'll give you a 2' by 2' sheet of this stuff free,
but here's the catch.  I want you to immediately try it out, write up a
review, and send me a pcb with a test pattern on it.

Things to know: Aqua Mer PR120 is a negative-acting UV-curing photoresist
that can be applied with a laminator.  Recommended developer is a 0.85%
solution of anhydrous potassium carbonate or sodium carbonate monohydrate.
I've put the data sheet at http://www.cs.csubak.edu/~dgriffi/00654.pdf.
