Summary of Conference Call on Electronic Fabric Industry Industry Overview - The conference call focused on the electronic fabric industry, specifically discussing advancements in PCB (Printed Circuit Board) technologies and materials used in various architectures such as GP300, GB200, and Rubin series [2][4][6]. Key Points and Arguments 1. **Material Upgrades and Usage**: - GP300 architecture has reverted to PCB solutions, increasing PCB usage and material grades. The Rubin series is testing PTFE1 and Ma9 grade materials, with NV actively evaluating Ma9 materials [2][4]. - GP300 employs HDI design with approximately 20+ layers, while GB200's actual layer count increased from 30 to nearly 40 layers, significantly enhancing CCL (Copper Clad Laminate) and BS (Binding System) material usage and value [2][6]. 2. **Price Changes**: - In GB200, the computer section is priced around $500-$600, while the switch section exceeds $1,000. In GP300, the switch section's value increased by 30%, from $1,000 to $1,500 [7][8]. - The Rubin series is expected to see a price coefficient increase of 2-2.5 times, with each board potentially exceeding $4,000 [7][8]. 3. **Supply Chain Dynamics**: - There is a significant disparity in yield rates among glass fabric manufacturers, with major suppliers including Asahi Glass (Japan), Taiwan Glass, and Taishan Fiberglass (China) [10][11]. - Ordinary fiberglass is priced around 10 RMB, while first-generation Low DK is priced at 30-40 RMB, and quartz (Q) prices are at least double that of the second generation [14]. 4. **Testing and Evaluation**: - The M9 and QQ material testing is being conducted in three tiers, with NV having completed initial evaluations and AWS, Google, and Meta expected to finish testing by Q3 2025 [3][16]. - The performance of quartz fabric varies significantly between manufacturers and even between batches from the same manufacturer, indicating instability in quality [17]. 5. **Market Demand and Supply Challenges**: - The demand for electronic fabrics is expected to increase, with potential supply bottlenecks anticipated in the mid-range output due to tight supply of first-generation Low DK glass fabric [29][30]. - The expansion cycle for electronic fabric production typically takes 1 to 1.5 years, with quartz fabric potentially requiring an additional 20-30% more time [28]. 6. **Future Trends**: - The initial pricing of new electronic fabrics is typically around 2.5 times that of the previous generation, decreasing to below 2 times during mass production, with a target stabilization at 1.5 times [31]. - The market for second-generation fabrics is expected to remain tight, with prices likely to hold steady due to high demand and limited supply [35]. Additional Important Insights - The current focus on testing indicators emphasizes DK and DF values, with stability in performance being a primary concern [27]. - The entry of new suppliers into the electronic fabric market is cautious, with established relationships and technical capabilities being prioritized [20]. - The market share for first-generation electronic paper suppliers shows that the top three suppliers account for approximately 60% of the total procurement volume [32][33]. This summary encapsulates the critical discussions and insights from the conference call, highlighting the evolving landscape of the electronic fabric industry and its implications for future investments and market dynamics.
