G C Electronics now owned by Waldom website www.gcwaldom.com They
make a spray pos. photo resist. Believe that Kepro use to have a
neg. photo resist but they are no longer in business. Right off
hand I do not know of stocking dealers not a product that I normally
buy. Seems this topic was talked about several months ago.
Yes it is not a easy process to get it right, I tried it a long time
ago and was never pleased with the results, after I think 3 attempts
I quit, was only having maybe 2 out of 12 boards come out OK. Was
spending way too much time for what I was getting out of it.
I believe the best way is to apply resist is a dry film laminate. I
think you will find that it is easier to buy the boards already
presensitized. I buy the M.G. Chemicals pos. resist boards 600
series. They work good. Good source is Circuit Specialist
www.circuitspecialist.com or www.webtronics.com They carry in
stock most items needed to make your PCBs as well as other parts. I
buy most electronic parts from Mouser Electronics and Allied
Electronics. Mouser is starting to carry some PCB materials again
they had dropped most of it for awhile. But Circuit Specialist
currently has better pricing if you are buying 12 or more boards at
a time.
