Connection Systems

GB-matrix

The GB-matrix connectors consist of parallel rows of gold-plated brass wires in a silicone rubber sheet. They are used for a permanent connection between PCBs or for a PCB to a component.

SS-SG type

The SS and SG are carbon elastomers for z-axis connections to LCDs. All are custom-made for particular applications but usually, do not require any special tooling. They consist of a series of conducting and non-conducting silicone rubber supported by a softer rubber on each side providing stability. The SG-type has a softer support rubber.

GB-E and GB-U types

These connectors replace the carbon with gold-plated brass wires giving a higher current-carrying capacity and a stable low-resistance connection. They are used for PCB to PCB connection or PCB to component applications. Uses include a microphone, speaker, battery and sensor connection. The GB-E provides a Z-axis connection of one or more rows, whilst the GB-U is a u-shaped version as the name suggests.

JC and JS types

The JC- type consists of a PET-film substrate with printed carbon tracks. A connection between LCDs and PCBs is facilitated by heat bonding the anisotropic adhesive at either end of the film substrate. The JS-type is similar but the carbon tracks are replaced by silver ones giving a lower resistance for perhaps LCDs with fine-pitch contacts.

MT-type

The MT-type is used for testing IC devices in packages such as BGA, QFP, SOP, Flip-Chip or Bumped Wafers. They consist of parallel rows of gold-plated brass wires in a silicone rubber sheet. They have a high wire-density and provide a stable low resistance connection. Derived from the GB-type, the MT-type is dedicated to the field of device testing. The basic MT-type has contact pitch of 0.1mm on a 0.5mm thick sheet whereas the MT-4X derivative can offer a 0.05mm pitch on a 0.15mm thick sheet.
