HI,just made my first arduino pcb's.They turned out quite well except um, after 7-10 days now the whole copper side has started going black. (1)Is there a way to prevent it.I hv seen green coating on professional ones.Is there a cheap alternative to elongate their life? (2)Also drilling turned out be a hell of an affair.I dont wanna buy a drill press and working with my hand drill to drill them was a nightmare.Any solutions? Thanks!
Side note :- I didn't want to create a new post to spam but an out of context question.I am making a biped and I bought some servos.They had with them a main horn screw but no side horn screws(the real tiny ones) .Any substitutes?
