Jack of all trades, master of none, as the saying goes, and that’s especially true for PCB prototyping tools. Sure, it’s possible to use a CNC router to mill out a PCB, and ditto for a fiber laser.

The advent of cheap and accessible one-off PCB production has been one of the pivotal moments for electronic experimenters during the last couple of decades. Perhaps a few still etch their own boards, ...

CNC machining mills away copper using a CNC router and design software chemical etching uses UV light, photo-resist, and chemicals to remove copper CNC machining is safer and less wasteful, but slower ...
