The problem of mismatch between pin headers and PCB hole positions

What should I do if the number or position of the component pins does not match the hole positions on the PCB?

Please first confirm that the component model (MPN) you provided is consistent with the package in the design document. If it is confirmed that the hole position design is incorrect, it is recommended to readjust the hole positions according to the component data sheet and remanufacture the circuit board.

If only a few pins cannot be inserted, the redundant or interfering pins can be pruned after confirming that they do not affect the function. However, this operation may cause component damage. Please handle it with caution.

To avoid similar situations, please carefully check the BOM and packaging information before placing an order. PCBfast engineers will synchronously check and alert in advance of possible design mismatch issues during the file review stage.
