Has anyone done a PCB using the new chips with the BGA (ball grid array)?
If so, how did you define the footprint?  As through-holes?  Fab shops must
be capable of accommodating these ICs otherwise they wouldn't exist.

I'm thinking they must be easy to solder since it would simply fall into
it's position with either pre-soldered holes or pre-soldered pins/balls.
