MAF-type of Inter-Connector

The MAF-type of Inter-Connector, developed for small height connections and testing substrates of PCB's or FPC's and electronic components, is a anisotropic sheet of silicone rubber with brass fibers dispersed in the Z-axis. The protruded surfaces of the bras fibers are gold plated.

Custom designs are generated by punching out required shapes from standardized sheet sizes. Additional adhesive layer are available to ease assembly. Fibers protrude the adhesive layer.
