I rarely make PC boards, but do when I have a need for something really special. Other people seem to get by with toner transfer. I got set up with Riston dry-film resist from think-n-tinker. This stuff is quite amazing. You need a transparent master artwork. I built my own laser photoplotter, but you can get by with a GOOD laser printer. Check your laser printer by printing a 1" grid twice, then flip one of them and lay them on a light table. If the grids don't line up well, then that printer is not a good candidate for double-sided PC boards.
The PC board needs to be super-clean, I scrub them with fine sandpaper, water wash and then finally wipe with acetone before laminating the resist.
I have a Kepro laminator specially made for this process, but I think there are other hot-roll laminators that will also laminate a rigid board.
exposure is in a vacuum frame made of thin Plexiglas with a bank of filtered fluorescent black light bulbs. That takes a 1 minute exposure per side.
Let the boards sit for 10-15 minutes for polymerization to complete, then develop in warm sodium carbonate for 1-2 minutes. Wash in water and dry.
Etch in warm Ferric Chloride spray etcher for about 3 minutes, and it is done. SMT is great, a LOT less holes to drill.
