Kulicke & Soffa Introduces ASTERION™-TW: A New Era in Ultrasonic Terminal Welding

Kulicke & Soffa Industries, Inc. (NASDAQ: KLIC), a prominent player in the semiconductor assembly solutions sector, has unveiled its latest innovation: the ASTERION™-TW ultrasonic terminal welding system. This sophisticated technology is set to revolutionize the manufacturing of next-generation power modules, marking a significant advance in the realm of semiconductor solutions designed for high-performance applications.

A Leap Forward in Power Module Manufacturing

The ASTERION™-TW builds on Kulicke & Soffa's established reputation in interconnect technology, specifically focusing on ultrasonic, solid-state terminal welding. This breakthrough offers an innovative alternative to traditional mass-reflow methods, particularly for high-reliability applications across critical sectors, including renewable energy, transportation, and data centers.

One of the standout features of the ASTERION™-TW is its robust bonding capability, which allows for the welding of copper terminals measuring up to 2 mm in thickness. This is critical for ensuring the integrity and performance of power modules that must withstand demanding operational conditions. The system employs a high-resolution linear motor positioning apparatus that guarantees a ±40 microns placement precision, vital for achieving optimal results in power electronics.

Flexible Design for Manufacturing Excellence

The ASTERION™-TW is designed with versatility in mind, featuring a ±180° weld head rotation, and a generous vertical stroke of 150 mm which facilitates access into deep cavities. This is complemented by a work area of 300 mm x 300 mm, accommodating various assembly requirements. Additionally, an optional material handling system includes an inline pallet conveyor complete with high-force clamping and an integrated cleaning station, enhancing the overall efficiency of operations.

Environmental Benefits and Efficiency

The move towards ultrasonic terminal welding with ASTERION™-TW heralds significant environmental advantages. By employing a solid-state bonding process, this technology eliminates the need for external heat, consumables, adhesives, and harmful chemical byproducts that are common in traditional methods. As a result, the utilization of this system means lower energy consumption, zero emissions, and improved recyclability of the integrated components, thus promoting greener manufacturing processes.

The management of weld force is another critical feature of this system, ensuring consistent contact while minimizing sensitivity to variances in tolerances. The inherently low-waste process of the ASTERION™-TW enhances adaptability for evolving power module designs, allowing manufacturers to adjust more swiftly to changing market demands.

Commitment to Innovation and Customer Collaboration

Ivy Qin, the General Manager for Ball & Wedge Bonding at Kulicke & Soffa, stated, "ASTERION™-TW reflects our commitment to deliver high-performance interconnect solutions through engineering excellence and close collaboration with our customers." This highlights the company's dedication to leveraging deep process expertise alongside market-driven innovation to empower their clientele.

As part of its strategy to broaden its power interconnect offerings, Kulicke & Soffa's solutions now encompass a diverse range that includes the ASTERION line, covering wire and ribbon wedge bonding methods, as well as pin welding processes with the ASTERION™-PW system, in addition to the new terminal welding capabilities of the ASTERION™-TW.

Premier Debut at SEMICON China 2026

The ASTERION™-TW system will be showcased during the SEMICON China trade show, taking place in Shanghai from March 25 to March 27, 2026. This event offers the perfect platform for the introduction of the ASTERION™-TW alongside other innovative solutions from Kulicke & Soffa, allowing attendees to experience firsthand the cutting-edge technology that is set to shape the future of semiconductor assembly.
