Don't Let Perfection Be the Enemy of a Perfectly Good PCB

摘要

DOES YOUR PCB quality team inspect to pass or inspect to fail? Knowing the difference between what is rejectable in a printed circuit board and what is a nonissue is more important than ever. Skyrocketing costs, shortages of copper and fiberglass materials, and longer delivery times mean remakes are not available as quickly as before. Rejecting PCBs for things that don't affect the form, fit or function of the final project is simply bad business. To be clear, I am not advocating acceptance of substandard product. IPC-A-600 standards are clear as to what is good and what is not. But thanks to lack of training or misinterpretation of industry specs, incoming PCB quality inspectors are turning away perfectly good commercial-grade boards that then must be remade.
