Re: [Homebrew_PCBs] TT technique, removing toner after etching leave part of it on the epoxy

2007-11-01 by Stefan Trethan

Yes, and acetone is cheap.
But i am cheaper and that would use way too much of it for my liking.
I think it depends a lot on the toner how well it flakes off with
mechanical scraping.
Mine comes off very easily so i prefer that.
