Recently, the hotspots in the PCB concept have mainly focused on AI-driven industry growth, corporate expansion, and outstanding performance. Here are the specific details:
AI Technology Drives Demand Growth: AI technology is pushing PCBs towards high density and refinement, with AI servers exhibiting exponential increases in performance requirements for PCB products. As the core carrier of high-end PCBs, HDI is continuously gaining penetration in scenarios such as 5G base stations, data centers, and smart vehicles. NVIDIA has launched the next-generation inference chip GPURubin CPX, which will become a new growth driver for the AI PCB market.
Industry Returns to an Upward Cycle: Benefiting from a low industry base and the rapid expansion of high-end application fields such as artificial intelligence, the PCB industry is showing signs of recovery. In the first half of 2025, driven by the continuous demand for AI servers and high-performance computing, the industry is maintaining a growth trend, with sub-sectors like HDI and HLC performing particularly well.
Companies are Expanding Production: Currently, the supply of high-end PCB products in the market is not sufficient, prompting leading companies in the industry to increase investments in key processes and bottleneck processes. For example, Shenghong Technology will continue to expand the production capacity of high-end HDI and high-layer boards; Dongshan Precision’s wholly-owned subsidiary, Chaoyi Group, plans to invest no more than $1 billion to build a high-end PCB project; and Pengding Holdings plans a capital expenditure of 5 billion yuan in 2025, a year-on-year increase of 51.5%, mainly directed towards projects including the Thailand park, flexible board expansion, and high-end HDI and SLP projects in Huai’an’s three parks.
Stock Performance is Impressive: Over the past three months, the PCB sector has been hot, with five companies including Shenghong Technology, Jingwang Electronics, Dongshan Precision, Shenyang Electronics, and Huadian Co., Ltd. achieving stock price doubles, and Yihua New Materials seeing a 98.75% increase in three months, nearing a double.
Breakthroughs in Upstream Materials: Recent technological breakthroughs and capacity expansions in upstream core materials such as electronic-grade fiberglass, specialty resins, and copper foil have laid the foundation for industry explosion. CITIC Securities estimates that the market space for high-frequency and high-speed resins used in servers will reach 2.28 billion yuan by 2026, corresponding to a compound annual growth rate of 85% from 2024 to 2026.
Trends in Factory Establishment in Southeast Asia: In recent years, domestic PCB manufacturers have been intensively expanding production and establishing factories in Southeast Asia. According to Prismark’s forecast, from 2024 to 2029, Asia (excluding China and Japan), represented by Southeast Asia, will become the region with the highest compound annual growth rate, reaching 7.8%.
