. did not provide the recommended hole size. But if you had to calculate a hole, it would be non-plated with a +/- 2 mil (0.05 mm) tolerance and 2 mil larger than the maximum peg diameter

;There is also a Toolbox with a Pad Stack Calculator. You can either enter the terminal lead length width or the hole size length and width and it will calculate all the pad stack details.

) and the hole size tolerance is 0.075 mm, the pad size annular ring must be 0.125 mm or a pad size of 0.25 mm over the hole size. The second tolerance that needs to be applied to calculate the pad size is the layer to layer registration
