Doosan to Build New CCL Production Line in China’s Changshu

Doosan Corp., the South Korean electronics company, is set to expand its production capacity for copper-clad laminate (CCL) in China by building a new production line in Changshu City, Jiangsu Province. This expansion is part of the company's broader strategy to strengthen its global manufacturing network and meet growing demand for high-end electronic materials.

The investment agreement was signed on November 6, 2022, with Changshu City, following a meeting at Suzhou City Hall on November 5, attended by Suzhou Mayor Wang Wei, Doosan President Yoo Seung-woo, and Kim In-wook, head of Doosan's Electronic Materials Business Group.

The investment, part of a KRW 970 billion plan announced in September, will see approximately KRW 550 billion allocated to China. The new facilities, to be constructed on a site of around 185,000 square meters near an existing Changshu plant, will be built in phases through 2028, with operations commencing in the second half of 2028.

Doosan plans to utilize its local workforce and infrastructure, having operated a CCL plant in Changshu since 2012. This move is anticipated to enhance production efficiency and bolster the company's responsiveness to Chinese market demands.

Changshu City has pledged support for the project, offering assistance in approvals, registrations, licensing, and other administrative procedures. The expansion comes as demand for high-performance CCL materials continues to rise, driven by the proliferation of advanced semiconductor and electronic products. CCL, a crucial component in printed circuit boards, is increasingly required for applications demanding high-speed signal transmission, high-density circuit designs, and superior thermal management.

This move is poised to reinforce Doosan's standing in the high-end CCL market by augmenting its production capacity and diversifying its supply network geographically. In October, Doosan also announced plans to build a dedicated facility for optical-module CCL in Gimje, North Jeolla Province, at a cost of KRW 399.2 billion through 2028.

In April, the company revealed intentions to construct a new plant in Thailand. With these recent investments, Doosan is establishing a global CCL production network connecting South Korea, China, and Thailand. President Yoo Seung-woo affirmed the company's commitment to these expansion initiatives, emphasizing their role in delivering timely and high-quality products to meet customer needs and solidifying Doosan's leadership in the high-end CCL market.
