Hello Gurus;

Trying to get a general idea of package buildup and geometries. If I imagine a 
package as a miniaturized PCB, I would expect all geometries to shrink.

For a state of the art, 1500 pin, FCBGA, what are typical numbers for:

1. Trace width.

2. Via, pad, antipad diameters.

3. C4 Bump pitch.

4. For the bump breakout, how many traces can you put between the traces.
