The explosive growth of AI servers, high-speed communications, and other cutting-edge applications has pushed PCB material performance requirements to new heights in 2025. Meanwhile, core material supply security and technological upgrades have become key factors for enterprises to build competitive moats. Let’s explore the technology trends, material innovations, challenges, and future prospects of the PCB industry this year

To support signal transmission rates of up to 112Gbps and even 224Gbps inside AI servers, the demand for high-speed laminates of M4 to M6 grades has surged dramatically. These materials minimize signal attenuation and crosstalk, ensuring stable and reliable data transmission in high-frequency, high-speed scenarios.
The ABF substrate market for GPUs and AI chips is particularly vibrant, with major manufacturers ramping up production capacity to meet the skyrocketing demand from AI computing infrastructure projects.
HDI technology is advancing toward any-layer interconnection, enabling higher component integration in smaller spaces. Meanwhile, the consumer electronics sector’s pursuit of slimmer and lighter designs is driving the wider application of ultra-thin PCBs and flexible PCBs.
Copper Clad Laminate (CCL), the “foundation” of PCBs, is critical to supply security and technological advancement.
Vertical integration shows advantages. Enterprises like Kingboard Laminates Holdings, which have built integrated supply chains by producing upstream key materials in-house, demonstrate strong competitiveness in ensuring supply stability and controlling costs. Their high-speed materials are widely used in AI PCs and servers.
Copper foil technology keeps innovating. New types of copper foil are being widely adopted to enhance high-frequency performance, meeting the strict requirements of AI server PCBs for signal integrity.
Environmental requirements become the benchmark. Halogen-free materials have become the standard configuration in the consumer electronics sector, aligning with global environmental regulations and sustainability trends.
The industry has broad prospects, but challenges are equally prominent.
Key challenges: Overcapacity in the mid-to-low-end segment in mainland China has triggered fierce price competition; high-end technological barriers still exist; geopolitical uncertainties continue to bring variables to the global supply chain.
Future outlook: The global PCB output value is expected to reach approximately $98 billion in 2025 and is poised to exceed the $100 billion mark by 2030. AI and data centers will remain the core growth engines, and Southeast Asia will be the fastest-growing region in terms of production capacity. However, mainland China and Taiwan China’s dual advantages in scale and technology will be difficult to shake in the short term.
2025 is an era of “the strong getting stronger” for the PCB industry. Mainland China and Taiwan China form the dual core of the industry with their scale and technology advantages. Southeast Asia, as a rising manufacturing force, is growing rapidly and reshaping the global capacity map. The technological theme of “high speed, high frequency, high reliability” resonates throughout the entire industrial chain.
For every player in the industry, seizing the AI wave, mastering advanced materials and processes, and achieving successful global layout will be the key to determining the future. As the outlook suggests, entering high-barrier tracks with cutting-edge technology, ensuring supply security through global layout, and replacing simple OEM with in-depth collaboration may be the rules for opening up new horizons in fierce competition in 2026.
