I'm wondering if there are any usable techniques for etching a PCB (a copper board) without sinking a board into chemicals, by any potential manual/hand techniques.
If there are, I'd like to know about some of them, as well as how costly (if very specialized tools are required), cluttery, and accurate they can be (accuracy in this case should definitely depend on your hand and practice as well), either by your opinion, or if you know a source that already describes all of them, that should be sufficient.
