>
> 2800 components; top & bot placement allowed, few placement restrictions
> ~20,000 pads/pins, 95% SMT
> Usable area: 130 in2
> Routing layers: 8 internal routing, top&bottom
> Plane layers: 10 power/gnd planes; 6 voltages distributed on split
> planes
> Trace/space: 4/6 mil
> Via drill/pad: 10/20 mil
> 4200 nets; ~80% involve matched lengths and/or differential routing
> Major components: 1020 ball 1mm BGA, 1508 ball 1mm BGA, 1072 ball 1.27mm
> BGA, 2x SODIMM sockets, 12 HD connectors
> All digital; no analog
>
> A full-feature SPECCTRA router is available.
