It is how the electronic boards are made. I used to make electronic deer feeder timers, I would print the master on a transparency sheets, then iron them on the copper boards. Dump in the acid and the copper would be eaten away. For some special boards, I used a Sharpie as the resistance, the acid wouldn't eat through the Sharpie lines.
