Homebrew PCBs

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
