Copper Glass-Coated Micro Wire features glass insulation for use in semiconductor wire bonding. Is a replacement to traditional copper bonding wire or gold wire. Is cast, not drawn, to enable a soft metal core with a high strength, ultra-fine glass coating. Is said to eliminate anti-oxidation, enabling a longer shelf life. Supports larger spools, for simpler materials management. Protects against shorts since the wire is coated and cannot make contact. Scale to 4 microns.
