The surge in AI computing power demand ignites the PCB market, with multiple concept stocks rising strongly. Industry prospects are promising.

Today, China’s A-share market saw a broad-based rise among PCB concept stocks. Several related companies posted strong share-price performance. Among them, Tongyu New Materials capped the daily limit-up with a 20CM gain, becoming a market focal point. Minbao Optoelectronics and Weilgao also performed well, with both rising more than 10%. Tienyi Technology closed with a 10CM limit-up. Meanwhile, Shengquan Group, Qiangli New Materials, Hongchang Electronics, Copper Crown Copper Foil, and others all saw gains of more than 6%. Yihau New Materials and Dongcai Technology rose by more than 5%. Nanya New Materials, Huazheng New Materials, and Meilian New Materials all climbed by more than 4%. Victory Macro Technology also recorded a gain of nearly 3%.

Market analysis holds that the strength of PCB concept stocks is closely tied to optimistic expectations for industry prospects. In recent investor activities, Victory Macro Technology disclosed that, with the rapid development of globally applicable artificial intelligence technologies, demand for AI training and inference continues to expand, driving prosperity in the AI computing power and server markets. This trend raises higher requirements for PCB products: not only does demand increase significantly, but product performance must also be upgraded in parallel. AI PCB is therefore viewed as the most certain growth direction for the industry’s future, providing strong momentum for relevant companies’ development.

From a technical perspective, the PCB industry is undergoing a significant upgrade. The ongoing improvement in signal-transmission bandwidth and continuous enhancement of material grades are driving increases in the number of layers and the levels of advanced HDI products, including high-layer-count boards and higher-tier HDI offerings. At the same time, the processing time for certain production steps has lengthened and complexity has risen, resulting in a reduction in the effective output area of high-end capacity. However, this shift has also caused product unit value and production-value capability to rise in tandem. Industry insiders note that, in the medium term, supply of high-end PCB products will remain tight, while downstream markets’ ability to absorb incremental capacity is sufficient—laying a solid foundation for the industry’s sustained growth.
