Kulicke and Soffa Industries, Inc. (NASDAQ: KLIC) has announced the launch of Asterion-PW, an advanced ultrasonic pin welding solution that enhances efficiency, precision, and reliability in power device applications. With this latest innovation, K&S continues to strengthen its leadership in semiconductor assembly solutions, catering to the growing demand for power modules in renewable energy, automotive, and railroad applications.
The power module market is among the fastest-growing semiconductor segments, with an expected compound annual growth rate (CAGR) of 12% through 2029. As these modules increasingly rely on pin-based interconnects for critical power storage and delivery, the need for precise, high-speed, and reliable interconnect solutions has surged. Asterion-PW addresses these demands by leveraging ultrasonic pin welding technology, which is rapidly replacing traditional soldering in critical applications.
The Asterion-PW integrates a high-resolution linear motor positioning system and an innovative, patent-pending Sonotrode design, achieving fine precision in pin placement repeatability. The system is equipped with a high-speed bulk pin feeder and an optional material handling system, ensuring seamless operation. An advanced cleaning station effectively removes contaminants before encapsulation, improving product quality and reliability.
One of the standout features of the Asterion-PW is its durable Sonotrode, which offers one of the longest operational lifespans in the industry. This results in fewer changeovers, reduced maintenance costs, and enhanced cost efficiency. By eliminating the need for flux and solder paste, the ultrasonic Sonotrode also provides clear environmental benefits, making Asterion-PW a more sustainable alternative to traditional soldering techniques.
Chan Pin Chong, Executive Vice President and General Manager of Products and Solutions at Kulicke & Soffa, emphasized the significance of this breakthrough, stating, “Precision drives innovation, and innovation transforms possibilities into realities. The Asterion-PW for power module applications is where innovative technology meets performance and cost-of-ownership benefits, redefining the future of manufacturing.”
In addition to the Asterion-PW, K&S has also introduced ATPremier MEM PLUS, a next-generation wafer-level packaging solution designed for high-volume memory applications. This breakthrough deploys Vertical Wire technology to support advanced memory solutions, further expanding K&S’s portfolio in semiconductor manufacturing.
