Message for Adam and/or Tom, But open to anyone (Those two just have made it known they've done some higher volume processing) What would you suggest for a person wanting to make perhaps 20 9x12 boards a day (gonna use 8x11 of this), but not necessarily every day. In other words, figure 100 boards this size per month (these are the "paneled up" size; I'll shear and/or route the final board sizes from these panels). But I don't want to make pcb's every day! One week a month sounds okay, which is how I got the 20 bds/day figure. I have pcb drills (obviously<G>), and can screen print. Doing it already for lettering of PU painted metal. I can make rectifiers for the plating. What size "line" would I need to set up for two sided THP, soldermasked, SMD (not fine pitch) boards? So what I'm asking is, going beyond the one or two at a time, but not quite into the low end of the PCB mfrs. price structure, what should I do? (And what can I expect?) Is setting up a line this size mostly about preserving/gaining the ability to make quick revisions? Or could it be fairly called money- saving?
