Re: engraving bits for PC board routing

There is also a pcb etching list. not nearly as popular as this, but
very useful.

One of the things I found is that routing PCB's kills carbide and is
slow. I saw a post that mentioned using dykem (prussion blue) and
painting your copper as it is a great resist. Then just scratching
off where you want the copper to be etched, Then etch in a chemical
tank. Best of both worlds, CNC accurate, as well as fast and sharp
edges.

A cheap and dirty method is to just cut the traces between circuits
and leave 99% of the copper. routing a board with mostly PCB and
tiny traces takes 10 times as long.
