I have to reverse engineer a controller pcb for one of the power analyzer tools at my work since there aren't any replacement parts available any more.
I desoldered all the components from the pcb but can't really see the traces. Does anybody know how to remove black or green solder stop masks from manufacturered pcbs to get to the clean copper traces again? Are there any chemicals that will remove this stuff ?
