Vacuum chuck for PCB milling and engraving.

Tony,

Outstanding video! I'm ready to take the plunge (pun intended).

I just drilled some #65 holes in a circuit board at 5,000 RPM and 0.5 IPM. It worked fine. I know I can feed faster but didn't want to push it yet. First problem I had was securing the board. That vacuum fixture is exactly what I need. A friend of mine was an expert on drilling tiny holes for GM and he said 5,000 RPM is fine as long as I peck deep holes. However, for engraving, I beleive I will need to up where you are.

Thanks for the great information.

Rick
