These include precise positioning and rotation, image recognition to detect the exact weld location, and derivation of an optimal trajectory to reach the weld location quickly and precisely.
Together with long and narrow welding tools, this allows flexible layouts and very tight spacing without positioning tolerances, and thus more compact products or higher power density in packages. Further advanced functions include touchdown sensing, precise and dynamic contact force control, and standardized interfaces for assembly line integration.
The diverse process control features include monitoring of ultrasound characteristics and deformation, compatible with automotive applications and DVS 2811 recommendations. Smart Welding Machines can, like ultrasonic wire bonders, handle a large variety of products. New products only require a program change and possibly adapted clamping and automation.
