Press-Fit PCB Hole Size and Validation: 1.45 mm vs 1.475 mm
The dimensions of PCB press-fit holes directly affect the quality of component press-fit connections, as well as the electrical performance and reliability of the entire PCBA. In this WellerPCB case, an initial trial showed visible damage, prompting a revised 1.475 mm nominal finished-hole target and validation on two bare boards before SMT. Both samples passed […]
