Our product line includes connectors, terminals & headers, power surface mounts and single & multipin headers. Our 9700 series of connectors designed to maintain the mating between the shells by providing protection against EMI. Our high temperature cofired ceramic package (HTCC) is a multilayered, sealed and highly reliable package created using layers of ceramic tape with thicknesses ranging from 5 to 25 millimeters, which are laminated together. The cofired ceramic packages' tape layers, consisting of 92 percent aluminum oxide ceramic, tungsten and molymanganese, have metallized circuit patterns. The ceramic package tape layers are laminated under pressure and the ceramic and metallization are co-sintered at 1600 degrees celsius, creating a monolithic structure with a three dimensional wiring system.
