SCHUNK Sonosystems ultrasonic metal welding solutions provide solid-state, solder-free joining for advanced power electronics, EV batteries, wire harnesses and cooling systems. Pressure and high-frequency vibration create strong, homogeneous Cu, Al and selected Cu-Al joints without melting or added solder, flux, adhesive or filler. Applications include power-module terminals, busbars, shunts, DBC/ceramic substrates, leadframes, PCB contacts, pins, rivets, battery foils, tabs, BMS assemblies and high-current connections. Key advantages include low thermal input, short cycle times, high conductivity, repeatable weld quality, mixed-material capability and reduced stress on heat-sensitive components. SCHUNK platforms support process monitoring, data capture, traceability, SECS/GEM connectivity and automated line integration. AGA provides application analysis, feasibility trials, tooling, process development, system selection, commissioning and local technical support across Asia Pacific.
