I made several UV PCBs back in the 70s. Gosh has it been that long
ago! As I recall it took
1) Develop the artwork
2) Print out the artwork
3) Expose the negative (Dark room setup)
4) Develop the negative (Dark room setup)
5) Expose the PCB (Negative pressed to PCB with pane of glass and
weights using dark room setup)
6) Develop the PCB (Dark room setup)
7) Etch the PCB
8) Cut to size and drill the PCB

I realize now there are positive sensetive boards and steps 4 and 5
are not used.

What steps and equipment do you use to make PCBs?
