AI应用驱动PCB行业景气上行，PCB材料迎来重大机遇

Summary of Key Points from the Conference Call Industry Overview - The global PCB market is experiencing continuous growth, with a projected total output value of $73.6 billion in 2024, where mainland China accounts for 56% of the market, making it the largest production region [1][7] - The multilayer board segment holds the highest market share, with HDI multilayer boards benefiting from the increasing demand for high-density electronic products. The global HDI market is expected to grow at a CAGR of 8.7% from 2023 to 2028, reaching a market size of $16 billion by 2028 [1][7] Core Insights and Arguments - High-performance AIDC PCBs are crucial components in AI servers, high-speed switches, and autonomous driving systems, with core components including motherboards and power backplanes. The value of a single PCB in NVIDIA's AI servers can reach between $8,000 and $10,000 [1][9] - High-frequency and high-speed copper-clad laminates must meet stringent requirements for signal transmission speeds of 10-50 Gbps, with specific demands on impedance, signal dispersion, and loss performance [1][9] - The dielectric constant (DK) and dissipation factor (DF) are critical for high-frequency and high-speed circuit boards, with DK values typically ranging from 3.3 to 3.6 and DF values between 0.002 and 0.004 [1][10] Material Demand and Trends - Hydrocarbon resin is a hot material in the high-frequency and high-speed copper-clad laminate sector, with DK values below 2.6 and DF values below 0.001. It accounts for 30% of the 5G high-speed copper-clad laminate market, with demand estimated between 12,000 to 15,000 tons [1][11] - The global demand for electronic-grade polyphenylene ether (PPO) was approximately 1,000 tons in 2022, expected to rise to 8,000 tons by 2026, driven by AI server demand, resulting in a CAGR of 68.2% [2][12] - PTFE is recognized as the best resin material for high-frequency and high-speed copper-clad laminates due to its superior dielectric properties, with demand projected to reach 714 tons by 2026 for AI servers [2][13] Market Risks - Potential risks include slower-than-expected AI development or underperformance in the general PCB market [3] Key Materials in PCB Supply Chain - Key upstream materials in the PCB supply chain include electrolytic copper foil, electronic fiberglass cloth, and various types of resins, each serving critical roles in conductivity and insulation [4][5][6] Future Growth Trends - The global PCB market is expected to grow at an annual rate of 5%, with the fastest growth in applications related to server storage, projected to have a CAGR of 11.6% from 2024 to 2029 [7][8] Major Players and Competitive Landscape - Notable companies in the hydrocarbon resin sector include Japan's Tohoku, Dongcai Technology, and Shengquan Group. In the PTFE market, key suppliers include Rogers and Panasonic. The PPO market is led by Sabic and Shengquan Group [14] Conclusion - The development of data centers and AI servers is driving new requirements for PCB materials, particularly in terms of dielectric constant and loss factor, necessitating advancements in resin technology and additive materials [18]
