[dorkbotpdx-blabber] printed circuit board chemistry

[Daniel Johnson]

Hi all,

I've heard that a lot of people want to recover copper from the
process of making home made circuit boards.  A chemist friend of mine
thinks they can help, but needs to know some more information about
what process people are using.  She seems to be especially versed in
hazardous waste disposal.

What are dorkbotters using for making boards, and what do you have
problems with?
