Estimated reading time: 2 minutes

AT&S AG continues its strong growth path in the new year. Given the continued strong order situation and numerous major projects won in recent months, the company is investing massively in the infrastructure of the Leoben site. Following the successful commissioning of the state-of-the-art competence center for R&D and IC substrates production in summer 2025, AT&S is launching the next phase of its site offensive: With an investment volume in the mid-single-digit million range, the capacities in the existing printed circuit board plants will be comprehensively expanded and modernized.

AT&S is on the upswing

“After a challenging year and a half, things are looking up again,” says Michael Mertin, CEO and Chairman of the Management Board of AT&S. “The driver is artificial intelligence. It is therefore crucial to invest boldly in our own capabilities, especially in a challenging global economic environment.” Mertin adds: “Our decision to consistently expand production in Leoben-Hinterberg is a clear commitment to quality and a strategic step towards securing our technological sovereignty and our ability to supply our customers in the long term.”

Cleanroom area tripled

The key facts: the cleanroom area, which is essential for high-tech production, at the main plant in Leoben will be tripled from 760 to 2,300 square meters. As this new cleanroom extends over two floors, the elevator system and staircase will also be built using cleanroom technology. In addition, the quality of the cleanroom will be raised by one quality class to ISO6. Office, storage and logistics areas will also be converted. The expansion should be completed by summer 2026. “The conversion includes state-of-the-art production facilities and optimized logistics processes that will take the site to the next technological level,” says Barbara Decker-Schlögl. As Senior Director Operations and the new site manager, she is coordinating all activities with her team. “We are significantly increasing our capacities. We owe this expansion to a consistently strong order situation for special embedding products and it is a huge vote of confidence in the expertise of our team.”

AT&S CEO Mertin also refers to the increase in production staff. “In the fall, we announced 150 new jobs in Leoben and the feedback was great. With our IC substrates as essential components for new cloud and AI applications and our renowned expertise in highly developed printed circuit boards, AT&S is ideally positioned globally and here in Austria.”
