Custom PCB Etching
April 25, 2010
Today I picked up the chemicals and parts needed for custom PCB printing. I will be doing a run tomorrow on a single sided PCB (no need to waste a nice double sided on the first try). I found out about an interesting way to reuse the chemicals over many many runs which should reduce the overall waste produced.
Here is the instructable with the method I will be using: http://www.instructables.com/id/How-to-make-a-printed-circuit-board-PCB-using-th/
I won’t be building a UV light since I will be using our saltwater aquarium lights which should do the job about 1000x faster. Here is more information on the chemicals used and why they are a bit more earth friendly: http://www.instructables.com/id/Stop-using-Ferric-Chloride-etchant!–A-better-etc/step4/Chemistry-Break/
