The company said Tuesday it will establish a new local entity and build a CCL plant at the Araya Industrial Park in the Bang Bo area of Samut Prakan province.
Total investment will be about 180 billion won. The site will cover about 73,000 square meters. Doosan plans to break ground within this year and aims to begin mass production in the second half of 2028. It said it will consider phased capacity expansions in line with demand to improve investment efficiency.
The Thailand plant will mainly produce high-performance CCL for AI infrastructure and network equipment, the company said, adding it expects strong growth as global demand expands.
Doosan cited logistics and operational stability as key reasons for choosing the site. The industrial park is about a 30-minute drive from Suvarnabhumi International Airport and about an hour from Laem Chabang port. The company also said the newer complex has operating infrastructure and disaster-response systems that support stable production.
CCL is a sheet made by laminating copper foil onto both sides of an insulating material and is a core base material for printed circuit boards, or PCBs. Doosan said AI accelerators, which must process massive amounts of data at very high speeds, require high-performance CCL that minimizes signal loss and resists deformation in high-temperature operating environments. As investment in AI data centers grows worldwide, demand for high-performance CCL is rising rapidly, it said.
Doosan said it has built competitiveness in CCL on materials technology accumulated over the past 50 years, including an edge in designing the “optimal composition ratio” among materials that determines CCL quality.
“We decided to expand production capacity to respond in a timely way to growing CCL demand,” a Doosan official said. “We will monitor market conditions and flexibly review whether additional investment is needed.”
