Jiaocheng Ultrasonic and TE Connectivity signed a strategic cooperation
agreement at the 2026 Munich electronica show to jointly tackle barriers to
full-scale aluminum-for-copper substitution in automotive wire harnesses. The
partnership will expand use of ultrasonic welding in harness assembly, aiming to
move the technology from single-point validation to industry-wide mass
production and support an innovation ecosystem for widescale rollout.
