Summary of Conference Call on Low CTE Material Demand for iPhone 17 Industry and Company Involved - **Industry**: Electronic Materials, specifically Low CTE (Coefficient of Thermal Expansion) materials - **Company**: Apple Inc. (iPhone 17) Key Points and Arguments iPhone 17 and Low CTE Material Demand - iPhone 17 is expected to adopt INFOP packaging technology, increasing the demand for Low CTE materials. The projected shipment volume for iPhone 17 in 2026 is 223 million units, leading to a total demand of approximately 56.77 million square meters of Low CTE fabric, with raw material demand estimated at about 84.45 million meters per year after yield compensation [1][3] - The introduction of LCD wave fabric in iPhone 17 will reduce the usage of ordinary wave fabric by approximately 0.06 square meters per unit, resulting in an annual total demand of about 54 million square meters [1][6] Supply Situation of Low CTE Materials - The supply of Low CTE fabric is currently tight, with major suppliers including Asahi and Zhi Dong Fang, while domestic supplier Honghe Technology is beginning small-scale production [1][4] - The demand for Low CTE materials is expected to continue increasing due to requirements from AR chips, GPUs, ASIC chips, and Nvidia's packaging technologies [1][4] Pricing and Market Dynamics - The market prices for ordinary electronic fabrics 1,017 and 1,027 are approximately 120 RMB overseas and 90 RMB domestically. Low CTE electronic fabrics are priced about three times higher than ordinary fabrics [2][7] - The average price of Low CTE glass fiber fabric is around 145 RMB per square meter, significantly higher than traditional glass fiber materials [31] Future Demand Projections - The growth of AI chips, including Nvidia GPUs and ASICs, is expected to double the demand for Low CTE materials next year. AI chip substrates typically require new boards with Low CTE glass fiber, which will further increase demand [2][32] - Global monthly demand for Low CTE materials is close to 1 million square meters, with overseas demand accounting for 600,000 to 700,000 square meters [23] Supplier Strategies and Capacity Expansion - Apple has begun stockpiling materials for iPhone 17, with a global stockpile estimate of 120 million units, primarily sourced from Japanese suppliers [2][12] - Suppliers like Honghe are actively expanding production capacity, with Honghe's factory in Huangshi adding 50,000 square meters of capacity per month [24] Material Usage in iPhone 17 - Each iPhone 17 is estimated to require about 0.25 square meters of fabric, with Low CTE materials accounting for approximately 0.025 square meters per unit [27][28] - The proportion of Low CTE fabric in iPhone 17 is about 1/9, indicating a significant increase in usage compared to previous models [43] Conclusion - The demand for Low CTE materials is set to rise significantly due to advancements in technology and the introduction of new products like the iPhone 17. The supply chain dynamics, pricing strategies, and supplier capabilities will play crucial roles in meeting this demand in the coming years [1][2][4][32]
