MPX-16 census

I can't *prove* you wrong. But I've spoken with someone who claimed to have done it, and when I started asking questions, talked a good enough line that I found it believable. As she described it, you need epoxy/fibreglass mix, which you cast a thin sheet of. You then sand it smooth, copper-plate it, and etch. Slap on another coat of epoxy and fibreglass, let it cure, sand it smooth, copper-plate, and etch. Lather, rinse, repeat. The hard part is of course quality control (and plated-through vias, which you can get somewhere with by drilling holes before doing the last copper-plating). And registration of the layers. But with patience and attention to detail...after all, anyone doing this is considering time to be worth a great deal less than money, or the job would simply be shipped off to a commercial pcb fab house. :) /~\ The ASCII der Mouse \ / Ribbon Campaign X Against HTML mouse at rodents.montreal.qc.ca / \ Email! 7D C8 61 52 5D E7 2D 39 4E F1 31 3E E8 B3 27 4B
