Ron,

 

Instead of printing the resist, why don't you cover the whole board with
resist and burn off the unwanted areas with the laser?

Has anyone used an ink jet printer to direct print resist on copper clad
PC board? I saw a youtube video where someone made a fixture for an
Epson printer that can print on CD-ROMs. The fixture holds a 3.5" x 2.5"
x 1/32" board  (or some such size). Another video used a printer without
a fixture and standard ink, but baked the ink to dry it. I have played
with laser toner transfer in the past and have found it to be a pain.

 

CD-ROM fixture - special ink

no fixture -- standard ink -- bake

Of course the cats meow would be (might be?) a direct print conductors
process. Someone, (Mike?) was telling me about directly screening on PC
board conductors using something like a high temperature solder paste --
sounded interesting. 

 

Thanks,

Ron
