Since 2026, multiple PCB listed companies have disclosed expansion plans, with a focus on high-end production capacity. Industry insiders believe that the domestic companies' layout (layout) of high-end PCB production capacity is primarily driven by factors such as the rapid growth in demand for downstream AI servers, new energy vehicles, advanced packaging, the arrival of the window period for import substitution, and the contraction of high-end production capacity by overseas manufacturers. Ji'an ManKun Technology is advancing a high-end PCB production base project in Thailand, which is expected to commence operations in 2027. In addition, companies such as WUS Printed Circuit, Zhen Ding Technology, and Shennan Circuits have also announced investment plans for high-end PCB projects. Industry insiders point out that the supply of high-end PCBs is tight, with a significant gap between supply and demand. The industry is at a critical juncture for industrial upgrading and will exhibit polarization in the future, with import substitution advancing deeper.
