The innovation project "Intelligent production of reliable copper bond connections" in the excellence cluster “it’s OWL” aimed to develop intelligent processes and systems that ensure reliable mass production of copper bond connections even under variable production conditions. The entire process of ultrasonic connection formation was modeled. This includes a friction model with a coupled connection model, the ultrasound softening effect and the wear of the bonding tool. In addition, a concept of a self-optimizing bonding machine was created, which adapts process parameters depending on disturbance variables such as wear.
