Flip Chip Ball Grid Array (FCBGA) package with 1202 solder balls. The die size is currently 9.6

2.2
Non-Grid Array Package Ball Placement
The 945G Express Chipset GMCH package utilizes a “balls anywhere” non-standard grid ball
pattern. Minimum ball pitch is 0.8 mm (0.031 in.), but ball ordering does not follow a 0.8 mm
grid. Board designers should ensure correct ball placement when designing for the non-grid array
pattern. For exact ball locations relative to the package, contact your Intel field sales
representative.
