Lines: 14 Help! Could anyone give me some pointers on photoetching circuit boards, or a source for some reliable information (maybe a book or something). I've tried a couple of times but not got the quality that I am looking for. Also, I was wondering if a red light can be used as a safety light (ie photo developing) and if it mattered whether the board is developed with flourescent or incandescent. A friend and I were working from recollections of how the original instructions we read told to photoetch. Any help will be greatly appreciated. Thanks. --Curt coorswol@alchemy.tcnet.ithaca.ny.us
