ZDT-led China PCB expansion tops US$10 billion on AI server and edge AI demand

China's PCB industry is entering a new wave of capital investment, with commitments exceeding $10 billion by 2026, driven by surging demand for AI servers and edge computing devices. This shift is reshaping the entire semiconductor supply chain, particularly in high-speed signal transmission, HDI, and flexible circuit technologies. Upstream suppliers of copper foil, solder mask, and drilling equipment stand to gain, while midstream manufacturers face pressure to scale and upgrade. Geopolitical tensions between the US and China are increasing compliance costs and supply chain risks, pushing firms to localize production. International players like Siliconware and Amkor may accelerate investments in mainland China to circumvent trade restrictions. Within the next 12 months, the sector will see intensified competition in high-end products, with self-reliance becoming a survival imperative. If AI demand continues to outpace forecasts, global PCB markets could surge further, with China capturing over half the global share.
