Package mechanical drawings and data information

The following notes are related to Figure 63 and Table 73:

FPBGA stands for Fine Pitch Plastic Ball Grid Array.

Fine pitch: e < 1.00 mm pitch.

Low Profile: The total profile height (Dim A) is measured from the seating plane to the

top of the component.

The maximum total package height is calculated by the following methodology

(tolerance values):

The typical ball diameter before mounting is 0.55mm.

Pitch (SQ. & RECT.)

The tolerance of position that controls the location of the pattern of balls with respect to

datums A and B. For each ball there is a cylindrical tolerance zone eee perpendicular

to datum C and located on true position with respect to datums A and B as defined by

e. The axis perpendicular to datum C of each ball must lie within this tolerance zone.

The tolerance of position that controls the location of the balls within the matrix with

respect to each other. For each ball there is a cylindrical tolerance zone fff

perpendicular to datum C and located on true position as defined by e. The axis

perpendicular to datum C of each ball must lie within this tolerance zone. Each

tolerance zone fff in the array is contained entirely in the respective zone eee above.

The axis of each ball must lie simultaneously in both tolerance zones.
