Markus, and others who have done these things on a limited budget:
Would you please describe your process, or provide a pointer to some
such description on the web?



I have made a few small double sided boards using photosensitized
boards, but haven’t attempted PTH’s or multilayers.



I have heard of a product that might be of use in making multiplayer
boards: There are thin sheets of copper on some sort of insulating
backing material. The sheets are thin and flexible enough that they can
be run through a laser printer. (Small pieces can be cut out and taped
to a full-size sheet of paper before sending through the printer.) The
laser toner protects the copper, so the copper sheet can then be etched
immediately. I read about this product and how to use it in a hobbyist
electronics magazine around 1995. Some hobbyist supply company offered
to sell small quantities of the material. The cost for ten 8 ½ x 11
inch sheets was less than $100 – maybe much less, I don’t remember.



Thanks,

- Jan
