A while ago (late '80s, early '90s) I heard a suggestion for using copier toner as
PCB etch resist
(draw on paper, copy onto overhead transparencies, iron onto the PCB).
Now that PCB layout software is available easily, as are laser printers, has anyone here
tried
it? I'm wondering how well it would resolve for finer-pitch DIP/SIP packages, or if
the etchant would eat
through the traces.
