[...] even i was unable to move the micro-desktop board (which is only 4in x 4.5in) forward because i had designed it as a 4-layer PCB - costs are around $400 for qty 5 4-layer prototype boards on a 3 week turnaround by complete contrast, a 7-day turnaround for qty 5 2-layer prototype (bare copper) boards with larger vias is around $40 for qty 2, and around $100 for qty 5.
Imbecile question: is it at all reasonably possible to redesign the micro-desktop board to be a 2-layer board?
yes, i've done it already. i do have to increase the via sizes from 10mil + a 20mil surround to 12mil + a 24mil surround to fit the rules of a lower-cost PCB factory that i know of, but other than that, it's done already.
