The GB-U-type of Inter-Connector, used for 
permanent board to board and component to board connections and for substrate testing, consists of a row of gold-plated brass wires in silicone rubber folded around a sponge rubber in a U-shape. Randomly positioning the Inter-Connector between contact pads and providing compression will realize a stable, low resistance connection.
The GB-U-type is the first design of a wide range of special custom designs of Inter-Connectors with additional moulding frames or holders for connecting microphones, speaker, coin-batteries, sensors and other electronic components.
Further to the basic GB-U-type, a special GB-UA construction has been designed to ease compression and provide superb stability for harsh environmental conditions like mechanical shock or vibrations.
