Note: 1 VFBGA stands for Very thin Profile Fine Pitch Ball Grid Array.
The maximum total package height is calculated by the following methodology:
A2Typ + A1Typ + (A 12 + A32 + A42tolerancevalues ) .
Very thin profile: 0.80mm < A ≤1.00mm Max/Fine pitch: e<1.0 mm
2 The typical ball diameter before mounting is 0.25 mm
3 VFBGA with 0.40mm ball pitch is not yet registered into JEDEC publications.
4 The tolerance of position that controls the location of the pattern of balls with respect to
datum 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 datum A and B as defined by e. The
axis perpendicular to datum C of each ball must lie within this tolerance zone.
5 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.
6 The terminal A1 corner must be identified on the top surface by using a corner chamfer, ink
or metallized markings, 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. Exact shape of each corner is optional.
