AI的下一战：高端PCB材料，一个千亿级的国产替代新战场（附60页PPT与解读、投资逻辑）

Group 1 - AI applications are driving the PCB industry towards a growth cycle, with expectations for both volume and price increases. The demand for high-end PCBs, particularly HDI and 18+ layer boards, is projected to grow significantly due to the rise in AI servers and 5G applications, with global market value CAGR estimates of 6.4% and 15.7% respectively from 2024 to 2029 [1][6][39] - Copper-clad laminates (CCL) are identified as the core substrate for PCBs, accounting for approximately 27% of PCB cost structure. Key raw materials include copper foil, resin, and fiberglass cloth, with high-frequency and high-speed CCL expected to see rapid demand growth in AI and 5G applications [2][5][21] - The demand for electronic resins is evolving, with a shift towards high-performance types such as PTFE, PPO, and hydrocarbon resins. These materials are crucial for meeting the high-frequency and low-loss requirements of modern PCBs, with domestic manufacturers making strides in achieving local replacements [2][7][12] Group 2 - The usage of high-performance silicon micro-powder is rapidly increasing, driven by the performance upgrades of downstream devices and the growing application of AI servers. The demand for silicon micro-powder in China is expected to reach 473,000 tons by 2025, reflecting a year-on-year growth of 13.2% [2][12] - The PCB market is projected to recover starting in 2024, with a growth rate of 5.8% and a sustained CAGR of 5.2%, indicating a new growth curve driven by AI demand rather than just cyclical recovery [21][29] - China is the largest PCB production base globally, accounting for 56% of the market value. The growth in the Chinese PCB industry is expected to come primarily from value enhancement rather than quantity expansion, emphasizing the need for high-end materials [24][29] Group 3 - The structure of the PCB cost is heavily influenced by the core materials, with CCL and prepreg accounting for over 41% of the total cost. The production of CCL involves complex chemical and material processes, indicating high technical barriers [58][59][72] - The demand for high-frequency and high-speed CCL is expected to grow significantly, with the market size projected to reach approximately $2.8 billion. This segment is characterized by faster growth rates and higher profit margins compared to the overall CCL market [96][97] - The evolution of electronic resins is critical for enhancing the properties of CCL and PCBs, with various types of resins being developed to meet the specific needs of high-frequency and high-speed applications [115][120][129]
