GB-Matrix-type of Inter-Connector

The GB-matrix-type of Inter-Connector, used for board to board and component to board connections, mainly for permanent connections, consists of parallel rows of gold-plated brass wires in a silicone rubber sheet. Randomly positioning the Inter-Connector between contact pads and providing compression will realize a stable, low resistance connection.

The GB-matrix-type is one of the derivatives of the GB-type. Dimensions and pitches are designed to customer requirements.

For testing purposes, the MT-types are more suitable, having tilted wires to ease compression and improve durability for multi compression.
