EU. Market Catalyst: NVIDIA’s M10 Test Launches PCBs into the Ultra-High-Speed Era
In March 2026, a supply chain move by AI leader NVIDIA sent ripples through the electronics industry. Their next-generation Rubin platform officially initiated supplier testing for M10, a new Copper Clad Laminate (Ccl) material. This is more than a simple material upgrade. It signals the PCB industry’s official entry into a high-frequency, high-speed era. This new age is driven by AI and defined by ultra-low loss and exceptional signal integrity.
The M10 testing targets critical components for the Rubin Ultra and Feynman platforms. These include orthogonal backplanes and switch blade motherboards. Compared to the previous M9 generation, M10 introduces multiple suppliers. This breaks single-source dependencies. More importantly, it sets a new performance benchmark. Signal loss is projected to drop by 30-40% compared to traditional FR-4 PCBs. This is crucial for meeting the rigorous transmission speeds and thermal management demands of 800G/1.6T optical modules and high-performance computing. If testing proceeds smoothly, mass production is slated for the second half of 2027. This will trigger a new cycle of large-scale procurement for AI server PCB materials.
II. PCB: More Than Just a “Skeleton,” It’s the “Neural Center” of AI Computing
To understand this shift, we must first look at the PCB itself. PCB stands for Placa de circuito impresso. It is often called the “Mother of Electronic Products.” It is a carrier where conductive circuits and connection holes are etched onto an insulating substrate, like a copper clad laminate.
Its core functions go far beyond physical support:
-
Electrical Connection: It provides stable circuit connections for all components. These include CPUs, GPU, memória, resistores, e capacitores.
-
Signal Transmission and Power Distribution: It ensures high-speed signals transmit without distortion. It also distributes power precisely to every component.
-
Heat Dissipation and Shielding: Under high-power AI chips, the PCB acts as an efficient heat path. It also provides electromagnetic shielding to ensure system stability.
Without high-performance PCBs, smartphones would not be so thin. Automotive electronics would not be as smart. The immense computing power of AI servers would be impossible. As AI computing demands surge, PCB technology is evolving. It is moving from traditional multilayer boards to advanced designs. These include higher layer counts, Interconexão de alta densidade (IDH), and rigid-flex structures.

The explosive growth of AI servers has directly reshaped PCB demand. Data shows that AI servers’ share of PCB demand jumped from 15% em 2025 to over 25% em 2026. The PCB value per AI server unit has increased by more than 30%. Layer counts have leaped from 16-20 layers to 28-36 camadas. This places extreme demands on manufacturing processes and materials.
2. Accelerating PCB Material Upgrades
NVIDIA’s M10 test marks a complete industry shift from standard FR-4. The move is toward ultra-low loss materials like M8, M10, and Panasonic’s Megtron series. Leading domestic CCL manufacturers have also started small-batch validation. This meets the needs of AI servers and 400G/800G high-speed optical modules.
3. The Global “Two-Tier” Competitive Landscape
-
Tier 1 (Manufacturing Dominance): Mainland China. As the world’s largest PCB production base, China’s capacity share remains stable at over 55%. Leveraging massive scale, fastest turnaround, and lowest cost, Chinese manufacturers have developed world-class capabilities in multilayer and Placas de IDH.
-
Tier 2 (Material Leadership): Japão, Taiwan, Coréia do Sul.
-
Japão: Holds the highest technological barriers in high-end materials. Companies like Panasonic and Sumitomo dominate the low-loss CCL market.

The industry chain division of labor is exceptionally clear. High-end materials upstream are controlled by Japan, Taiwan, and South Korea. These include specialty resins, ultra-thin glass fiber, and HVLP copper foil. Meio caminho Fabricação de placas de circuito impresso is dominated by Mainland China. A jusante, global AI, automotivo, and communication brands drive final applications.
4. Growth Forecast: A Defined Growth Path in the AI Era
PCB is a primary and direct beneficiary of the AI computing boom. It offers high growth certainty. According to IEK data, global PCB output was estimated at approximately 92.36 billion U.S. dollars in 2025. This represents an annual growth rate of 15.4%. Looking ahead to 2026, as AI infrastructure expands, the global PCB market is projected to reach 105.2 billion U.S. dollars. This is a growth rate of 13.9%. Some forecasts predict the global PCB market could exceed 137.8 billion U.S. dollars by 2035.
We can break down this growth into three phases:
-
Short-Term (2026-2027): The AI Server Volume Driver Phase. A compound annual growth rate (Cagr) de 28% para 35%. With the mass production of new materials like NVIDIA’s M10, high-end PCB orders will surge.
-
Mid-Term (2028-2030): The Multi-Driver Phase. This includes automotive electronics and 5G or 6G technologies. The expected CAGR is 22% para 28%. PCB automotivo crescimento, driven by ADAS and domain controllers, could hit 40% anualmente.
