That's the reason why polite PCB-designers are planning for a NC-via at least for those BGA-contacts, that you won't get a hold on otherwise. Of course this adds about 2 cent to the costs of PCB for each via, and thus never is done by any commercial hw-mf (except those who had a major field-change-order issue in their history). On the other hand, what's the "tools to open the case" worth for, which surely add to total cost of product as well?
Of course a few vias don't already make a nice protoboard yet, but at least *some* users with smd-soldering experience may benefit. As long as they had some schematics anyway. All this very suboptimal with regard to an "open phone". All my Sony-gadgets are more open, when it comes to this. At least for those i got pretty nice service-manuals incl. circuit diagrams for free. cheers j _______________________________________________ OpenMoko community mailing list email@example.com http://lists.openmoko.org/mailman/listinfo/community
