Copper ribbon boosts efficiency in laser bonding
Stephen LawElectronics Production / Materials materials production
HERAEUS PowerCu Soft Laser Ribbons (LRB) for Laser Bonding is an optimized copper ribbon that achieves improved efficiency and stability in power electronic systems. Product enables module operation temperatures higher than 250°C and allows the highest power density designs. Laser ribbon bonding is particularly suitable for joining bonding wire onto battery terminals and onto DCB substrates and copper terminals in power electronic modules. With laser bonding, the application of ribbon bonding for much higher currents is accomplished. Product is suitable for power devices and battery packages dedicated for high currents. One PowerCu-Soft LRB (0.3x2mm) can replace up to three 500µm Cu wires.
