Package Information and Contact Assignment
All dimensions in millimeters.
Dimensioning and tolerancing per ASME Y14.5M-1994.
Maximum solder bump diameter measured parallel to datum A.
Datum A, the seating plane, is determined by the spherical crowns of the solder bumps.
Parallelism measurement shall exclude any effect of mark on top surface of package.
