Contact tape is precision-formed bonded material designed to meet the requirements of high speed, automatic welding equipment for the manufacture of electrical contact assemblies. By precisely controlling the thickness of the component materials, a composite material system can be designed that minimizes precious metal usage, maximizes conductivity, and provides a resistive backing for attachment during the welding process of contact assemblies.
- Conserve precious metal
- Design lends itself to high-speed welding mechanization
- Options in weld projection design to optimize the welding process
- Low tooling cost
Mini Contact Tape
Umicore produces a mini tape (0.014” x .040”) containing a thin layer of Ag-Au-Pt alloy on a nickel base. This precious metals containing tape is used in relays to ensure high reliability of telecommunication and signal networks as well as other premium grade selector switches.
