Market Demand for High-End PCBs - The global AI infrastructure market is projected to grow significantly, with the market size expected to reach $124.03 billion by 2033, driven by rapid AI application deployment [25]. - AI server shipments are anticipated to rise sharply, with a forecasted shipment of 213.1 million units in 2025, reflecting a year-on-year growth of 27.6% [24]. Upgrading Server Requirements - The demand for PCBs is increasing as ordinary servers upgrade their specifications, necessitating higher performance CCLs [31]. - The global server shipment is expected to grow from 13.6 million units in 2020 to 16.3 million units by 2025, with a compound annual growth rate of 4.15% [31]. Market Growth Projections - The PCB market is projected to experience substantial growth, particularly in the server segment, with a compound annual growth rate of 11.6% from 2023 to 2028 [37]. - The high-end CCL market is expected to expand rapidly, with projections indicating a market size increase from under $4 billion to over $6 billion between 2024 and 2026, reflecting a compound annual growth rate of 28% [37]. Competitive Landscape - Japanese and Taiwanese companies hold significant advantages in the high-end CCL market, with major players like Panasonic and Rogers leading in high-frequency and high-speed CCL technology [38]. - The market for rigid special CCL is dominated by a few key players, with 13 companies accounting for approximately 93% of global sales [38].

Summary of Dongcai Technology Conference Call Company Overview - Dongcai Technology benefits from the growing demand for AI servers, with high-frequency and high-speed digital business rapidly developing. Revenue is expected to reach 270 million yuan in 2024, with projections of 600-700 million yuan for this year, primarily driven by the demand for AI servers like NVIDIA A100 [2][6][19]. Industry Trends - The core raw material for copper-clad laminates (CCL), resin, is undergoing an upgrade from traditional epoxy resin to polyphenylene ether (PPO), reactive ester resin, and BMI dual-cure resin. The trend is towards using PPO combined with hydrocarbon resin for level 8 CCL to meet higher signal transmission rates and signal fidelity requirements [2][7]. - The upgrade in terminal computing power demands is pushing the CCL levels from code 2 and 4 to code 7, 8, and even 9. The level 8 CCL primarily uses PPO combined with hydrocarbon resin [2][8]. Key Insights - Dongcai Technology has a strong position in the PCB materials sector, with market recognition of the increasing demand for terminal computing power and the company's advantageous positioning in this field. The release of production capacity aligns well with performance expectations [3]. - The company has established stable supply relationships with core downstream customers and has a reserve of 20,000 tons of high-frequency and high-speed resin, set to be operational by Q2 2026, providing a competitive edge over Japanese firms in terms of price and capacity [4][12]. - The high-frequency and high-speed resin business has seen a compound annual growth rate (CAGR) exceeding 100% since 2021, with expectations of significant breakthroughs in level 8 and 9 products by 2025 [4][16]. Product Performance - The high-frequency and high-speed digital business has shown rapid growth, with revenues increasing from 20 million yuan in 2021 to 160 million yuan in 2023, and projected to reach 270 million yuan in 2024 [6]. - The demand for special resin products, particularly the "Taoqin" resin, is expected to grow significantly, with monthly shipments projected to reach one million units by the second half of 2025 and annual demand nearing 20 million units by 2026 [10]. Competitive Landscape - The resin industry has significant barriers, including product quality, production management capabilities, and long-term cooperation with downstream manufacturers [15]. - Despite Japanese companies currently dominating the high-end digital product supply, domestic leaders are expected to capture most of the new market demand from 2025 to 2027 due to their price advantages and ample capacity [13][14]. Future Outlook - Dongcai Technology's future prospects are optimistic, with continued rapid growth in the high-frequency and high-speed resin business, expected to account for over 65% of profits. The company also anticipates growth in capacitor-grade BOPP films and optical base films through technological upgrades and market expansion [18][19].
