Ed,
How long does it take you to get a single board drilled, say 30 holes, 3
sizes?
I mean you start out with the layout files. generating drill files, making
them ready for the machine, setting up the machine (if you need),
positioning, aligning the board, putting in a drill, starting the
software, changing drills, until you have the drilled board in hand.
How long does that take you approximately?
Do you use free software, if not, what cost?
Do you drill before etch, if not, how do you align the drill with the PCB?
thanks
