Remove copper from a PCB without dissolving it? Answered
I have a bunch of old PCBs laying around from various electronic projects, things I took apart and re-purposed, etc...Seeing as copper is roughly $0.25 per ounce, I would like to remove the copper from these PCBs, and sell it to a local coin shop that buys various scrap metals. I plan on sanding the solder mask off first, but after that, I don't know how to remove the copper from the fiberglass. Maybe just electroplate it onto another piece of copper? Please give me suggestions, thanks!
