Pcb Hole Size Vs Pin Diameter at Poppy Bleasdale blog

Pcb Hole Size Vs Pin Diameter. If we want to design to class 2, then we should just use b = plating thickness (assume 1 mil for safety) on external layers and b = 0 in internal layers, meaning we would have a 18 mil diameter pad on all layers for a 10 mil drill hole with 1 mil via wall plating. Talk with your pcb maker about this. Metalized holes must to be drilled wider in order to accept the metal layer and still to be wider than the lead. Minimum hole size is calculated according to equations below: For level a minimum hole size = 0.55mm + 0.25mm = 0.80mm for level b minimum hole size = 0.55mm + 0.20mm = 0.75mm for level c. Three possible minimum hole sizes: Minimum hole size = maximum lead diameter + 0.25mm (for level a of ipc. If the size of the hole is too small, it is likely that the pins of the component cannot be inserted into the hole, resulting in the need to redo the pcb. For not metalized holes, simply add 0.1mm to. The hole diameter for a press fit is typically calculated using the following formula:

For level a minimum hole size = 0.55mm + 0.25mm = 0.80mm for level b minimum hole size = 0.55mm + 0.20mm = 0.75mm for level c.
