ultrasonic terminal welding technical

"announced ASTERION™-TW, a new ultrasonic terminal welding system designed"

Ultrasonic terminal welding is a manufacturing process that joins metal terminals, tabs or wires by pressing them together while applying high-frequency sound vibrations, creating a solid bond without melting. For investors, it matters because the method delivers fast, consistent connections that improve product reliability, reduce defect rates and lower production cost—similar to using a high-speed stapler that leaves a stronger, cleaner hold than gluing.

solid-state technical

"encompass new ultrasonic, solid-state, terminal welding."

Solid-state describes devices or components that rely on solid materials to perform their function rather than moving parts or liquids; examples include solid-state drives and solid-state batteries. For investors, it signals potential advantages like greater durability, faster performance, lower maintenance and often improved safety — similar to choosing a sealed, sturdy appliance over one with many fragile mechanical parts — which can affect product competitiveness, manufacturing costs and market demand.

linear motor technical

"A high-resolution linear motor positioning system provides ±40 microns"

A linear motor is an electric motor that produces straight-line motion instead of rotation, like taking a conventional spinning motor and unwrapping it into a flat track so a carriage can slide along it. Investors should care because this technology can make machines, factory lines, elevators, trains and robotics faster, quieter and more durable, affecting product performance, manufacturing costs, maintenance needs and market competitiveness — all of which can influence revenue and capital spending.

wedge bonding technical

"leader in semiconductor assembly solutions and wedge bonding technology"

Wedge bonding is a manufacturing method that uses a tiny wedge-shaped tool to press and attach very fine metal wire between connection points on a microchip or circuit, creating the electrical link that lets the device work. For investors, the technique matters because it influences product reliability, production speed, scrap rates and manufacturing cost — much like the difference between sturdy hand-stitching and a rushed seam affects the quality and cost of clothing.

wire bonding technical

"As a leader in high-volume wire bonding solutions, K&S offers"

A manufacturing process that uses tiny metal wires to connect a semiconductor chip to its package or circuit board so the chip can send and receive electrical signals; think of the wires as microscopic stitches that link the chip to the outside world. Investors care because the quality, cost, and scalability of this step affect product reliability, manufacturing yield, and supply-chain expenses—factors that influence margins, production bottlenecks, and the competitiveness of electronics makers.

SINGAPORE, March 24, 2026 /PRNewswire/ -- Kulicke and Soffa Industries, Inc. (NASDAQ: KLIC) ("K&S" or the "Company"), a global leader in semiconductor assembly solutions and wedge bonding technology, today announced ASTERION™-TW, a new ultrasonic terminal welding system designed to support next generation power module manufacturing. ASTERION™‑TW leverages K&S's longstanding leadership in interconnect innovation, expanding its established ASTERION platform to encompass new ultrasonic, solid-state, terminal welding. This solution provides a flexible, precise, and highly‑capable alternative to mass-reflow for demanding, high-reliability power applications supporting essential markets such as renewable energy, transportation and data center.

ASTERION™ -TW, with its high power and high force capability, enables robust bonding of copper terminals up to 2mm thick. A high-resolution linear motor positioning system provides ±40 microns (3σ) weld placement repeatability, supporting demanding power electronics applications. Designed for manufacturing flexibility, ASTERION™-TW features a ±180° weld head rotation, a 150mm vertical stroke for access into deep cavities, and a 300mm x 300mm work area. An optional material handling system includes an inline pallet conveyor with high force clamping and an integrated cleaning station.

Ultrasonic terminal welding offers compelling enhancements for high‑volume, critical power assembly by enabling a true solid‑state, no‑heat, bonding process. By eliminating external heat, consumables, adhesives, and chemical byproducts this ultrasonic capability enables green manufacturing through lower energy consumption, zero emissions, and improved recyclability of assembled components. Weld force control ensures consistent contact while reducing sensitivity to tolerances, and the inherently precise, low‑waste process provides greater adaptability to evolving power module designs.

"ASTERION™-TW reflects our commitment to deliver high performance interconnect solutions through engineering excellence and close collaboration with our customers," said Ivy Qin, General Manager of Ball & Wedge Bonding at Kulicke & Soffa. "By combining deep process expertise with market-driven innovation, we are dedicated to advancing our customers' capabilities."

As a leader in high-volume wire bonding solutions, K&S offers a comprehensive power interconnect portfolio. From the AVALINE™ clip attach solutions, to the growing ASTERION portfolio which now spans wire and ribbon wedge bonding with ASTERION, pin welding with ASTERION™‑PW, and now terminal welding with ASTERION™‑TW, these solutions reflect K&S's strategy to extend interconnect offerings while building on decades of ball and wedge bonding leadership and process expertise.

Visit K&S at SEMICON China 2026

Together with a broad portfolio of K&S solutions, ASTERION™-TW will debut at the SEMICON China Trade Show – Hall N3, Booth #3431 – in Shanghai, from March 25, 2026 through March 27, 2026. Please contact your regional K&S sales team for additional information.
