it seems like dupont and emerald are the two largest suppliers, but does anyone know of a distributor in the U.S. that stocks rolls of the film?
thanks!
The only source I have found for dry film is here http://www.thinktink.com/products/Soldermask.asp although the price is ridiculous unless you are making a LOT of boards. I have been hunting off and on for a year for anyone selling smaller rolls (group buy maybe?). The other choice I found (even more expensive even if you just purchase the consumables rather than the kit) is ProMask from LPKF http://www.lpkfusa.com/Store/pages/prod … px?pid=265.
In the end I decided that it was less expensive to just send boards out when I really need plated holes and masking.
