- Dear Knowledgeable ones,
- Up until now I have made my PCB's using donut and tape transfers on
- overhead proj film, exposing Electrolube +ve resist on the copper.
- However, as I have now entered the compuer age and bought a cheapy
- PCB CAD program, I need to produce masks from a laser printer.
- I tried the obvious (direct print on transparency), but the result
- was sufficiently porous that the copper looked like a 1/2 tone printers plate
- after etching. What should I do? I'm going to try inking over the printed
- bits on the mask, but that doesn't leave me a long way in front of the
- stick on donut method.
- Thanks,
- Graham B
