1. Values in inches are converted from mm and rounded to 3 decimal digits.

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

values and tolerances of A1 and A2.

3. Back side coating. Nominal dimension is rounded to the 3rd decimal place resulting from process

capability.

4. Calculated dimensions are rounded to the 3rd decimal place
