Power modules convert direct current (DC) from vehicle batteries into alternating current (AC), necessary for powering electric motors. This conversion is executed quickly with minimal energy loss. Precisely controlled power modules enhance performance, flexibility, and energy efficiency—not only in electric vehicles but also in applications like solar power systems and industrial machinery.
Soldering connections, crucial for electrical systems, currently face several challenges. These include imprecise positioning, uncontrolled individual connections, and long-term reliability issues. Additionally, traditional processes are often complex and space-consuming.
Addressing these challenges, Schunk Sonosystems has developed new technology for Ultrasonic Welding of pins and rivets aimed at providing greater flexibility, precision, and enhanced process monitoring. According to Dr. Reinke, this new solution improves efficiency by up to five times compared to conventional methods, crucially benefiting applications demanding exceptional quality and reliability.
Development of this technology required close collaboration with Infotech, a company known for its extensive expertise in handling and positioning. This partnership enabled precise yet rapid process execution, previously considered a significant challenge. Dr. Bürgi emphasizes the importance of adapting sensors and actuators to miniaturization requirements, as well as implementing a closely monitored, regulated single-step process, effectively reducing overall costs and processing times.
Customers choose Schunk Sonosystems and Infotech specifically for their unique combination of quality, efficiency, and speed. These factors are critical in the highly competitive power module market, where innovative technologies must excel to succeed.
Looking ahead, Schunk Sonosystems has ambitious plans. Dr. Reinke and Dr. Bürgi highlight that the company intends to enter new product categories with Ultrasonic Welding previously dominated by soldering technology. This move opens exciting market opportunities and growth potential for Schunk and its customers.
Through these innovations, Schunk Sonosystems continues to lead technological development, meeting the demands of a dynamic market.
