Posted: 13 Apr 2015 at 7:00am The Tolerance Deviation of -0.10 mm to +0.30 mm does not play into the mathematical model of the IPC-7351 land pattern calculation for the resulting pad size. You can enter -0.10 mm to +0.30 mm or

:54am Usually lower and upper deviations from nominal sizes are specified to be the same. However, that is not always the case. For example, nominal size can be specified to be
