IC substrates and networking PCBs grow; materials and equipment face shortages
The PCB industry is making large upgrades. The largest beneficiaries of the AI boom are IC substrate makers that are part of the advanced chip packaging supply chain, such as Unimicron and Kinsus, which have gradually emerged from the oversupply bottleneck caused by large-scale post-pandemic capacity expansion. The surge in orders has spread to multiple networking and server PCB manufacturers, including Gold Circuit Electronics (CGE), Allied Circuit Co. (ACCL), and First Hi-tec, driving double-digit year-over-year growth in Taiwan’s PCB manufacturing output value in 2025.
