NPI Services, Inc. most recent challenge was in supplying RF PWB’s containing both un-plated cavities and edge plated cutouts for specialty RF connectors. Cavities were needed to maintain a constant plane from SMT thin-film filters to wire bondage RF to die. The edge plated cutouts ensured ground plane contact with the RF connector body was sufficient to maintain the lowest possible VSWR. Not all CM’s elect to take on such a task, but this is what NPI is all about…supplying leading-edge technology in support of our customers R&D programs.
