Taiwan’s printed circuit board (PCB) sector is experiencing a surge in demand, driven by the burgeoning artificial intelligence (AI) market, with projections for continued growth until 2030. This boom is particularly impacting the market for CCL (copper clad laminate), a crucial PCB material. The leading CCL manufacturers in Taiwan – the “three heroes” – are now engaged in a fierce technological competition to capitalize on this trend. These companies are investing heavily in research and development to secure a competitive edge, addressing questions about potential oversupply and market fluctuations. The industry faces challenges, including fluctuating raw material costs and maintaining technological leadership. Despite these hurdles, the overall outlook for Taiwan’s PCB industry remains positive, fueled by the escalating demand from the global AI sector. The competition is centering on new materials and techniques to meet the demands of increasingly sophisticated AI applications.
