Co-Tech Development Corporation engages in the production and sale of electrolytic copper foils primarily used in printed circuit boards (PCBs) for information electronics, communication products, computers, consumer electronics, automotive electronics, and industrial control products. The company's core products include copper foil substrates, flexible copper clad laminates (FCCL), flexible PCBs, BGA carrier boards, chip on film (COF), and related materials such as fiberglass cloth, epoxy resin, and polyimide (PI). Co-Tech caters to markets in Taiwan, China, the rest of Asia, and the Americas. Founded in 1998 and headquartered in Taipei, Taiwan, Co-Tech was formerly known as Co-Tech Copper Foil Corporation until its name change in June 2014.
Recently, Co-Tech Development accelerated expansion of its high-value, low-profile (HVLP) copper foil production capacity, aiming to increase monthly output to 150 tonnes starting in 2026 and targeting over 1,000 tonnes monthly production by late 2027. This capacity boost is driven by growing demand for PCBs related to artificial intelligence servers and 5G communication applications, which is expected to improve the company’s gross margin to about 40%. The company is establishing new factories to support this growth and has reported substantial revenue increases, with 2024 revenues reaching NT$6.82 billion (approximately US$200 million) and significant share price appreciation in 2025. Co-Tech continues to invest in research and development to support product innovation in AIoT, cloud computing, automotive electronics, wearables, and home appliance markets.
The company operates under a technology sector classification with approximately 278 employees and key management including GM and Chairman Shih-Shen Lee. Its subsidiaries and investment activities complement its operations focused on copper foil and related copper-based electronic components. Co-Tech remains a strategic player in the electronic components supply chain, emphasizing advanced materials critical for next-generation electronics and communication systems in regional and global markets.
