Nvidia(US:NVDA)2025-07-30 02:32Summary of Conference Call Notes Industry Overview - The conference call discusses the impact of new technologies on the PCB (Printed Circuit Board) manufacturing industry, particularly focusing on the CoWoP (Chip-on-Wafer-on-Panel) and Carop (Chip-on-Board) processes, which are expected to enhance performance and efficiency in high-performance computing applications, especially for NVIDIA's GPUs and CPUs. Key Points and Arguments 1. New PCB Manufacturing Techniques - NVIDIA's new scheme utilizes embedded substrate materials, increasing the complexity of PCB manufacturing, requiring 1/3 oz copper foil or peelable copper foil [1] - The Carop process eliminates ABF substrates, directly mounting chips on PCBs, which necessitates higher flatness and tighter spacing [2] 2. Material Demand Changes - The demand for Low CTE (Coefficient of Thermal Expansion) electronic cloth has significantly increased due to the larger area of embedded substrates, which is now 3-4 times larger than before [1][5] - The annual demand for Low CTE glass cloth is projected to be around 750,000 square meters, with a monthly increase of approximately 4 million square meters expected to start in 2027 [14][15] 3. Supplier Landscape - Major suppliers of embedded substrate materials include Taiko and Dousan, with specific models like EM526, EM528, EMC892, and EMC896 being highlighted [3][4] - The market is also seeing contributions from Korean companies, although their market share is smaller [4] 4. Technical Specifications and Requirements - The new PCB designs require a minimum of 18 layers of Low CTE electronic cloth for 7 to 9 stage HDI (High-Density Interconnect) technology, doubling the previous requirements [10][11] - The increase in glass cloth layers to 10 is necessary to accommodate complex circuit designs [8] 5. Performance Enhancements - The new scheme is expected to double the computational power due to increased pin counts and improved design methodologies [9] - The transition to higher performance, lower dielectric loss systems is anticipated by 2027, with corresponding increases in PCB area and material requirements [29] 6. Challenges and Future Outlook - The production of high-layer PCBs is challenging due to thickness, small holes, and stringent flatness requirements, which may take years to achieve high yield rates [19] - The new COOP scheme has been researched and applied domestically, with limited international attention [18] 7. Material Composition and Quality - The resin system primarily consists of PPO and hydrocarbon, with increased purity requirements leading to a projected 10% increase in demand [21] - The use of HVLP (High-Volume Low-Pressure) copper foil is critical for meeting the new performance standards [36] 8. Market Trends - The overall demand for Low CTE glass cloth is expected to quadruple as new projects progress, with current monthly demand only in the hundreds of thousands of square meters [16] - The industry is moving towards more advanced materials that meet stringent performance criteria, including low thermal expansion and low shrinkage stress [40] Additional Important Insights - The transition to new technologies is gradual, with major companies like Google, Meta, and Amazon unlikely to adopt these changes in the short term [28] - The expected completion of new projects is projected for late 2026 to 2027, with significant ramp-up in production anticipated thereafter [17]
