2. - UFBGA stands for Ultra-Thin Profile Fine Pitch Ball Grid Array.
- Ultra Thin profile: 0.50 < A 0.65mm / Fine pitch: e < 1.00mm pitch.
- 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:
A Max = A1 Typ + A2 Typ + A4 Typ + (A1²+A2²+A4² tolerance values)

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.
