Doosan showcases CCL capabilities for AI accelerators at Europe's largest electronics fair

Doosan announced Wednesday that it is participating in Electronica 2026, an electronics components and systems exhibition running Tuesday through Friday in Munich, Germany (local time).

Electronica is Europe's largest electronics components and systems exhibition, bringing together companies in semiconductors, automotive, printed circuit boards, displays and sensors to present products and technologies and build industry networks. This year's edition draws more than 3,500 companies from roughly 60 countries.

At the show, Doosan is presenting a broad portfolio of electronic materials and components — including high-end copper-clad laminates, or CCL — used in AI data centers and servers, semiconductor packaging, automotive electronics, smart devices, and 5G and 6G communications.

The company is putting particular emphasis on CCL designed for AI accelerators and optical modules — components that transmit data between servers using light signals — both critical parts of AI data centers. CCL is a core material for printed circuit boards, the foundation of electronic circuitry, and its electrical, thermal and mechanical properties directly determine the performance and reliability of electronic products. The CCL for AI accelerators and optical modules features a low dielectric constant and low dielectric loss to enable fast signal transmission and minimize signal loss in high-speed data environments.

Doosan is also showcasing its patterned flat cable, or PFC, used in electric vehicle battery systems. PFC connects individual cells — the smallest unit of an EV battery — and is made by coating a flexible copper-clad laminate with an insulating film. It reduces weight and volume by more than 80 percent compared with conventional copper wire, contributing to lighter vehicles, lower costs and longer driving range. Doosan says it was the first in the world to develop and apply a roll-to-roll manufacturing process, enabling it to produce PFC up to 2.5 meters long — the full length of an EV chassis.

The company is also displaying a 5G antenna module, a key component of 5G wireless repeaters that applies beamforming technology to concentrate signal transmission and reception in specific directions.

Doosan has been posting record earnings on the back of surging CCL demand. Its Electronics Business Group, which leads the CCL business, recorded sales of 802 billion won ($592 million) in the third quarter of this year — the highest quarterly sales in the company's history. Doosan's standalone operations are expected to exceed 3.2 trillion won in annual sales this year, driven by the Electronics Business Group's performance.

To sustain the momentum, Doosan plans to step up overseas marketing while pursuing aggressive investment. The company intends to invest 420 billion won in domestic production lines for optical-module CCL by 2028, and spend an additional 550 billion won to build a new factory in China producing CCL for AI accelerators and network switches.

"This exhibition is an opportunity to demonstrate Doosan's materials capabilities — spanning AI infrastructure, automotive electronics and communications — to European customers," a Doosan official said. "We will incorporate market trends and potential customer requirements gathered on the ground into our development process, and follow up on leads to secure new clients."
