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. -- David Griffith dgriffi@...
