EU Chips Act Drives PCB Manufacturing Expansion Across Europe

EU Chips Act Drives PCB Manufacturing Expansion Across Europe

The European Chips Act, formally adopted in September 2023 with a mobilization target exceeding €43 billion in public and private investment through 2030, is no longer just a policy document. By mid-2026, its effects are rippling through every layer of Europe’s electronics supply chain — and the PCB industry is feeling the pull more acutely than most analysts predicted.

While headlines focus on semiconductor fabrication plants (the “mega-fabs” from Intel, TSMC, and Samsung), a less visible but equally critical transformation is underway: Europe’s PCB manufacturing infrastructure is expanding to meet the demands of a continent determined to rebuild its chip sovereignty.

The Semiconductor Catalyst

The numbers tell the story. Intel’s €30 billion commitment to its Magdeburg, Germany campus — now in advanced construction with first silicon expected in late 2027 — is the flagship project. But the ecosystem extends far beyond a single company:

• Infineon is investing €5 billion in a new 300 mm power semiconductor fab in Dresden, focused on automotive and industrial chips.
• TSMC’s European Semiconductor Manufacturing Company (ESMC), also in Dresden, is building a joint venture fab targeting 12 nm to 28 nm nodes for automotive and industrial customers, with a €10 billion total investment.
• STMicroelectronics is expanding its silicon carbide (SiC) production in Catania, Italy and its 300 mm fab in Crolles, France alongside GlobalFoundries.
• GlobalFoundries continues to expand its Dresden facility (Fab 1), the largest semiconductor plant in Europe by wafer output.

Each of these facilities requires a surrounding ecosystem of packaging, testing, and interconnect manufacturing — and that means PCBs.

Why Fabs Need Local PCB Supply

Modern semiconductor manufacturing and packaging facilities consume PCBs at multiple levels. Probe cards for wafer testing use ultra-fine-pitch HDI PCB technology with laser-drilled microvias and controlled impedance routing. Burn-in boards for reliability qualification demand high-layer-count multilayer PCB constructions with exceptional thermal stability. Load boards for automated test equipment (ATE) require tight impedance tolerances and high-speed signal integrity.

Beyond the fabs themselves, the downstream electronics manufacturers that cluster around semiconductor facilities need PCBs for their end products — automotive ECUs, industrial controllers, power modules, and telecom infrastructure equipment.

The logistics argument is straightforward: shipping PCBs from Shenzhen to Dresden adds 4–6 weeks of lead time, currency risk, and carbon footprint. For prototype and NPI (new product introduction) runs — the bread and butter of a new fab ecosystem — local supply is not just convenient, it’s essential.

Europe’s PCB Capacity Response

European PCB fabricators are responding. AT&S, headquartered in Leoben, Austria, and already one of Europe’s most advanced PCB manufacturers, announced in early 2026 a €200 million expansion of its Leoben facility targeting IC substrate and advanced HDI capacity. The company explicitly cited the EU Chips Act ecosystem as a demand driver.

In Germany, Schweizer Electronic AG is expanding its Schramberg facility with additional multilayer and embedding technology capacity. The company’s partnership with Infineon on chip-embedding technology positions it directly in the power semiconductor PCB supply chain.

KSG Group, one of Germany’s largest PCB manufacturers with facilities in Germany and Austria, has invested in new direct imaging and laser drilling equipment to support finer geometries demanded by automotive and industrial customers migrating to advanced nodes.

French fabricator CIMULEC, specializing in high-reliability and military-grade PCBs, is expanding capacity for aerospace and defense applications that benefit from the Chips Act’s strategic autonomy pillar.

Italy’s PCB sector, historically smaller, is seeing growth through companies like Somacis, which is expanding its rigid-flex and HDI capabilities to serve the automotive and industrial markets growing around ST’s expanded Italian operations.

The HDI and Advanced Technology Gap

Despite this expansion, Europe still faces a significant capability gap in the most advanced PCB technologies. The continent has virtually no production capacity for the ultra-HDI boards (line/space below 30 μm) or advanced organic substrates that leading-edge semiconductor packaging requires. These remain concentrated in East Asia — primarily Taiwan, South Korea, Japan, and mainland China.

The EU Chips Act includes provisions for “first-of-a-kind” facility support that could, in theory, subsidize advanced PCB/substrate manufacturing plants. Industry groups including EIPC (European Institute of Printed Circuits) have lobbied for explicit inclusion of PCB infrastructure in Chips Act funding mechanisms, arguing that chip sovereignty without interconnect sovereignty is incomplete.

Some progress is emerging. The Fraunhofer Institute for Reliability and Microintegration (IZM) in Berlin has expanded its panel-level packaging research line, which includes advanced redistribution layer (RDL) substrate prototyping — a technology that blurs the line between PCB and IC substrate. This public research infrastructure could seed commercial production if investment follows.

Impact on Global Sourcing Strategy

For electronics companies designing and manufacturing in Europe, the Chips Act ecosystem is changing procurement calculations:

Regional content requirements are tightening. While the Chips Act itself doesn’t mandate local PCB sourcing, associated EU regulations on supply chain due diligence (the Corporate Sustainability Due Diligence Directive, or CS3D) and the Carbon Border Adjustment Mechanism (CBAM) create economic incentives for shorter supply chains.

Dual-sourcing mandates post-COVID have already pushed many European OEMs to qualify at least one non-Asian PCB source. The Chips Act ecosystem makes European fabricators more viable candidates by expanding their capacity and technology range.

NPI speed favors local supply. When a new chip comes out of a European fab and needs immediate board-level prototyping, having a PCB fabricator within a day’s shipping distance cuts weeks off the development cycle.

Security-sensitive applications — defense, critical infrastructure, medical — increasingly require supply chain traceability that’s easier to guarantee with European fabrication. NATO member states are particularly focused on ensuring defense electronics PCBs don’t depend on geopolitically sensitive supply chains.

Challenges Remain

The expansion is real but not without headwinds. European PCB manufacturing costs remain 30–50% higher than Asian equivalents for comparable technology levels, driven by energy costs, labor rates, and regulatory compliance overhead. The skilled workforce gap is acute: experienced PCB process engineers are scarce in Europe, and training pipelines are thin.

Environmental regulations, while aligned with Europe’s sustainability goals, add cost and complexity. REACH compliance, restrictions on PFAS (which affect many PCB wet-processing chemistries), and upcoming Ecodesign for Sustainable Products Regulation (ESPR) requirements will challenge fabricators to reformulate processes while scaling up.

Energy costs, though moderating from 2022 peaks, remain significantly higher than in Asia. A PCB fabrication plant is energy-intensive — etching, plating, lamination, and curing all consume substantial power. European fabricators are investing in on-site solar and energy recovery systems, but the cost gap persists.

What This Means for PCB Buyers

For companies evaluating their PCB supply chain in 2026, the EU Chips Act creates both opportunity and urgency:

1. European PCB capacity is growing but still constrained. Booking production slots with European fabricators for 2027 and beyond should start now.
2. Technology capabilities are advancing. European fabs are investing in HDI, high-layer-count, and controlled-impedance capabilities that were previously Asia-only propositions.
3. Dual-sourcing is becoming easier. With expanded European capacity, qualifying a European source alongside an Asian primary supplier is more practical than it was three years ago.
4. Total cost of ownership is narrowing. When factoring in logistics, inventory carrying costs, carbon pricing, and supply chain risk, European PCB sourcing is more competitive than headline pricing suggests.

The EU Chips Act was designed to rebuild semiconductor sovereignty. Its most lasting impact on the electronics industry may be the broader supply chain ecosystem it catalyzes — and PCB manufacturing is at the heart of that ecosystem.
