Chris, I do not know of a supplier in Canada, but this link --> http://www.web-tronics.com/printed-circuit-board-supplies.html has inexpensive pre-sensitized positive photo etch boards. Using a black light will do a good job on these and you do not need a dark room. These can withstand a little time in a room with the lights on with no damage. The developer used is Anhydrous Sodium Metasilicate. They sell it as their part number posdev. There are probably other very good sources, but I see no one has answered your question as yet. Hope this gives you a start in your search. -Mike ----- Original Message ----- From: "Chris Graham" <Chrisgr@...> To: <Homebrew_PCBs@yahoogroups.com> Sent: Sunday, May 11, 2003 10:53 AM Subject: [Homebrew_PCBs] Photosensitizing boards > What's the easiest way to photosensitize copper boards and get high quality > results?
