Summary of Conference Call on CCL and Glass Fiber Demand Industry Overview - The conference call primarily discusses the **Copper Clad Laminate (CCL)** industry and the demand for **low DK glass fiber** materials, particularly in the context of AI technology and ASIC applications [1][2][4]. Key Points and Arguments 1. **Increased Demand for Low DK Glass Fiber**: The demand for low DK glass fiber is expected to exceed **7-8 million square meters** in 2025, primarily for ASIC and GPU applications [1][4]. 2. **Material Shortages**: There is a significant shortage of both low DK glass fiber and **马 8级别 (Level 8)** materials, which are crucial for AI accelerator cards [2][5]. 3. **Market Share of Glass Fiber Types**: The CCL industry predominantly uses first-generation glass fiber, which holds an **80% market share** in AI accelerator cards. Second-generation glass fiber is mainly used in Ethernet switches, while third-generation glass fiber is anticipated for future products but currently has limited capacity [1][8]. 4. **Price Sensitivity Among Customers**: Different customers exhibit varying sensitivity to material prices. North American clients prioritize performance over cost, while others focus on cost-effectiveness [10]. 5. **Production Capacity Expansion**: The CCL industry is expected to expand production capacity by **30%-40%** in 2026, with an increase in the number of product layers, such as the potential increase from **26 to 34 layers** for Google's next-generation TPU [11][12][32]. 6. **Performance Differences in Domestic vs. Imported Materials**: Domestic low DK glass fiber has shown performance improvements but still lags behind Japanese and Taiwanese products in terms of stability [6][21]. 7. **Certification Process**: The certification process for new low DK glass fiber typically takes about **one year**, depending on company strategies and customer requirements [7]. 8. **Future of Second-Generation Glass Fiber**: Second-generation glass fiber has limited applications primarily in specific areas like Google's TPU, and its future depends on cost reductions and increased production capacity [9]. 9. **Production Statistics**: South Korean suppliers produce approximately **1.4 million square meters** of CCL monthly, with **700,000 square meters** being Level 8 materials [14]. 10. **Price Gradients of Glass Fiber**: The price of first-generation glass fiber is around **$6 per square meter**, with second-generation being approximately **30% more expensive**, and third-generation costing about **30% more than the second** [15]. Additional Important Insights - **Market Gaps**: There is a potential gap in production capacity if market demand increases significantly [19]. - **Testing and Development**: Chinese companies are actively testing third-generation glass fiber, while Japanese firms are more conservative in their approach [18]. - **Material Composition**: CCL typically consists of four layers of copper foil, three layers of glass fiber, and three layers of resin, adhering to a **433 ratio** [23]. - **Profit Margins**: The profit margins for different types of CCL vary, with Level 9 materials expected to be priced at **double that of Level 8** materials upon mass production [28][29]. This summary encapsulates the critical insights from the conference call, highlighting the current state and future outlook of the CCL and glass fiber industry.
