Hi
Ive recently gotten into self etching my own pcb's ( toner transfer method ), with good results.
I needed a switch for a gssl and instead of buying the set, decided to etch one from gyrafs overlay file.
The switch works fine and im very pleased, although i did modify the file a little to leave bigger gaps between tracks.
Now ive got the bug im gonna etch a few projects..first the g9 mic pre ( as ive got a few of the parts knocking around already.
i have a couple of concerns with this, first, i use FR4 1 oz copper...ive seen a few using up to 3 oz copper, for high voltages, will 1 oz copper suffice for the g9 project, or is the 3 oz stuff just overkill ( extravagance ).
Also i would like to mask the copper side of my board for this project to prevent shorts, arching...anyone got any methods for this...im thinking maybe some sort of non conductive laminate spray / paint.
cheers
