ECT’s POGO Spring Contact Probes, including the Ostby Barton/Pylon Division, is the world’s leading manufacturer of POGO Spring Probes for testing bare and loaded printed circuit boards. Innovations in design, engineering and manufacturing processes have led the industry. From the development of the first snap-out or replaceable probe, in 1965, to more recent designs such as the high performance bias ball PogoPlus probe line. Contact Products R&D programs address engineering and materials issues that will affect PCB test for the next decade. Methods for maintaining electrical continuity in miniature probes, improved spring technologies, and probe head geometries are under continual review. Specialized proprietary test equipment has been developed to assess the effectiveness of new designs.
