High-Reliability Ultrasonic Welding Solutions for Power Modules
Ultrasonic Welding Solutions for Advanced Power Electronics
In power electronics manufacturing, the assembly of high-performance power modules—such as IGBTs, IPMs, and SiC devices—increasingly relies on advanced ultrasonic welding technology. SBT ULTRASONIC systems deliver highly reliable, robust connections for both high-load current terminals and control signal pins, offering significant advantages over traditional soldering processes.
Superior Electrical Performance The solid-state molecular bonding formed by ultrasonic welding minimizes contact resistance, significantly reducing conduction losses and maximizing overall electrical efficiency.
Intelligent Process Control Our advanced platforms feature real-time, closed-loop control over critical parameters—including welding energy, amplitude, and pressure—backed by full data traceability to ensure flawless joint consistency.
Extended Lifespan & Reliability Accelerated lifetime testing demonstrates that power modules bonded with SBT ULTRASONIC technology exhibit superior thermal cycling performance. This significantly extends operational lifespan, simplifies thermal management designs, and guarantees long-term system reliability.
