In college I used a quick circuit prototyping machine called QuickCircuit
by T-Tech. This machine milled out copper to create traces. We used
Protel's schematic capture and PCB layout tools, generated gerber files,
then used a cad tool provided by t-tech to isolate traces out. The machine
did the isolation with a mill bit, used drill bits of standard sizes for
through holes. It can do double sided boards. I did a bunch of school
related projects on this thing, and also some personal ones. I prototyped
my WG LV redesign using the QuickCircuit. I was able to get down to 5 mil
traces with 5 mil spacing using this thing!
I would LOVE to have one of these in the workshop at home...however, the
thing is a bit expensive. They have a web site, <http://www.t-tech.com/>,
with pictures and info, etc. It looks like they will send a free sample of
a pcb done with their equipment.
