Re: [Homebrew_PCBs] Second PCB attempt - 99% success!

2002-12-31 by Hans Wedemeyer

Great... No you can let it dry and not etch for several days! If you
wait too long the copper may oxidize and be more difficult to etch.
Use a waterproof marker pen to touch up any mistakes etc. There is no
magic to what kind of pen. a simple laundry marker works just fine.
