PowerCu soft laser copper ribbons are for laser bonding in power electronic systems.

Enable module operation temp. higher than 250°C. Alternative to wire bonding and tape automated bonding. Suitable for joining bonding wire onto battery terminals and onto DCB substrates and copper terminals. Have one-sided roughening to reportedly guarantee more reliable coupling of laser beam onto reflective copper surface. Can be processed with all currently available laser bond equipment. Ideal for power devices and battery packages dedicated for high currents. One PowerCu-Soft LRB (0.3 x 2mm) reportedly can replace up to three 500µm Cu wires.
