1. Values in inches are converted from mm and rounded to 4 decimal digits.

2. Low profile: 1.20 mm < A ≤ 1.70 mm / Fine pitch: e < 1.00 mm pitch.

The total profile height (Dim.A) is measured from the seating plane “C” to the top of the component. The

maximum total package height is calculated by the RSS method (Root Sum Square).

A Max = A1 Typ + A2 Typ + A4 Typ + √(A1² + A2² + A4² tolerance values).

3. The typical ball diameter before mounting is 0.40 mm

4. 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.
