William, some board manufacturing houses are able to manufacture class 3 PCB with 5 layer stacked microvia, some others can't manufacture only with dificulty two layer PCB at real density... so it's not a good answer. :) On the other hand the autorouter has a density limit caused by via rings (minimum mechanical drilling via is 6/16 mils) and board size. greetings, Vasile -- http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist
