Package dimensions

Table 45: TFBGA 6x6x1.20 56 2R10 0.50 - Package dimensions a b c

a. Max mounted height is 1.20mm. Based on a 0.27mm ball pad diameter.

Solder paste is 0.15mm thickness and 0.27mm diameter.

b. TFBGA stands for Thin Profile Fine Pitch Ball Grid Array.

Thin profile:

-The total profile height (Dim A) is measured from the seating plane to the top component

- A = (1.01 to 1.20) mm

- Fine pitch: e>1.00mm pitch

c. The terminal A1 corner must be identified on the top surface of the package by using a corner

chamfer, ink or metallized markings, indentation or other feature of package body or integral

heatslug.

- A distinguishing feature is allowable on the bottom surface of the package to identify the terminal

A1 corner.

d. 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.

.fff e

e. 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.
