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

2. The maximum total package height is calculated by the RSS method (root sum square) using nominal and

tolerance values of A1 and A2.

3. Back side coating. Nominal dimension is rounded to three decimal places, which results from the process

capability.

4. Dimension is measured at the maximum ball diameter parallel to primary datum Z.

5. Calculated dimensions are rounded to the three decimal places.
