Today I grabbed a un-etched PCB with a P&P (Press & Peel) circuit on it.
Then I rounded up a unregulated DC power supply, 10v-19v, 3.0 amp max.
After soldering a wire to the PCB and connecting it to the minus and the plus went to a small copper plate that I submerged in a plastic tray with enough water to cover. Made sure that the two didn't have a change to touch.
Than I added a little vinegar and a very small amount of table salt, don't ask me how much! Shortly thereafter bubbles started to form at the copper anode.
This was set up next to the kitchen sink, without my wife's permission!
Then I sat down to watch football, it was after all Sunday. During the advertising I went to check on my little experiment. No smell at all and couple of hours later about 95% of the PCB copper had migrated to the anode!
I should be able to etch the remaining copper with a standard etching solution in a matter of a few minutes at the most.
The advantage of all this is that you have much less exposure to noxious smells and of cause much less hazard's material to dispose of.
