WebJan 4, 2024 · For a 10 mil drill hole diameter, we would have an 8 mil finished hole size with a minimum pad diameter of 20 mils on all layers. This calculation uses: a = 8 mil for external layers, 10 mil for internal layers. b = 2 mil externally, 1 mil internally. c = 8 mil on all layers. WebNormally, when calculating the PCB hole diameter, the aspect ratio between the diameter of the hole and the thickness of the board is considered. If the thickness is 1.60mm, the hole size should be about 0.40. This means that the aspect ratio, in this case, is 1:4. Reducing the thickness of your PCB means that this ratio should also be reduced.
