Homebrew PCBs

Leon,

My drill speed is 10,000 RPM. How fast do you think a proper speed should be? And what kind of sharp drill do you recommend?

Thanks
Lanny

In the past, I used 2 pass drill to drill the hole, the 2nd pass, one 1 mill smaller but it doesn't seem to help much. I can increase the diameter of the via hole up to 50 mils.
