Has anyone found a good pcb board for milling and supplier? Also the same goes for bits and drills, and what others have used and found they would recommend, I ‘m only going to do CMOYS’s the are tiny headphone amps mainly for my own production. I’ve been loads of tutorials but none actually say what board they use , they do recommend software and some say what tools.

I 've seen this type of board from CPC wonder if anyone has used it ?
