Designer's Notebook: PCB Design for Bare Board Testing

March 22, 2023 | Vern Solberg, Consulting

There are several testing methods used for certifying that the circuit board meets its defined quality level and intended functional criteria. Multilayer circuit boards have become increasingly complex: finer conductor line definition, blind and buried microvia interface, and smaller, finer-pitch SMT land pattern geometries. Visual assessment using automated optical inspection (AOI) is adopted to check all circuit layers prior to lamination and as a final examination of the end product.

Informal information exists within most companies and distilling this knowledge into tools is not an easy task—maybe even an impossible one.
