Re: Part V: Tricks With PIC: Using the Trusty PIC Microcontroller

Q:  The problem with pcb manufacturers is it only becomes cost effective if you do multiple boards of the same type. Small batches etching at home is more cost effective.

 

A:  By the time you get all the materials, create a good 1:1 negative or positive film, etch the boards, and drill them, let alone deal with through holes, a commercial board service proves more economical and without the problems of safe and legal chemical disposal.  I have etched boards with a commercial UV-sensitive film and the results were OK, but not great.  Maybe the process has gotten simpler and the photo-sensitive films better, but even for small hobby projects it's a pain.
