"PGA Sockets
Tecknit's high performance PGA socket was the first socket that Tecknit developed to
interconnect printer circuit boards and integrated circuit devices. Using proprietary "Fuzz Button"
technology as the interconnect media, custom made PGA sockets offer reliable electrical
characterization and test results. Connection is made to each individual button upon
insertion of the pin grid device, and a gentle piping action ensures optimum pin contact.
Providing virtually "invisible" interconnection. Tecknit's PGA sockets are
used in high speed PGA test applications to ensure reduced signal distortion.
