400 MAPBGA—Case 17x17 mm, 0.8 mm Pitch
Figure 98 shows the 17
×17 mm i.MX25 production package. The following notes apply to Figure 98:
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.
