1. Values in inches are converted from mm and rounded to four decimal digits.

2. Ultra thin profile: 0.50 < A Max \u0001 0.65 mm / Fine pitch: e < 1.00 mm. The total profile height (Dim.A) is measured from

the seating plane “C” to the top of the component.

3. 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.

4. 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.
