Do you have much experience with the Haas machine? I use a
QuickCircuit at work, and anything smaller than the 10mil bits
is virtually impossible. I can't find a combination of bit
and feed speed that won't break the bits. 12 mil gaps is about
as fine as I can do reliably, saving the 8 mil to carve out gaps
between IC pads. Widths of course aren't much of a problem as
it's a subtractive process. EAGLE generates the gerber and
drill files for the quickcircuit software just fine, just getting
the flippin' thing to carve it out is a challenge. Time consuming
at best. A complex board takes hours and hours...
