2026-03-23 02:10Summary of Conference Call Records Industry Overview - The conference call focuses on the AI server and PCB (Printed Circuit Board) industry, particularly the advancements in materials and technology related to AI platforms and their components. Key Points AI Platform Upgrade - The new generation AI server architecture has shifted from "mid-board + CP board" to "switch backplane/orthogonal backplane + computing board," significantly increasing the requirements for backplane layers and material performance [1] - The Virtuoso cabinet inherits the GB300 design and upgrades materials, resulting in a 2x increase in PCB value, with each unit requiring 5 LPU cabinets and 1 CPU cabinet, all needing high-end PCBs [1] - This architectural adjustment is expected to increase PCB quantity by 2-3 times and value by 4-5 times, leading to a substantial rise in demand for copper-clad laminates (CCL) [1] Production Timeline - Core product mass production timelines are set: Rubin is expected to start mass production in Q3 2026, with PCB/CCL materials confirmed by late Q2 to early Q3; Alt in Q4 2026; and Fermi in the second half of 2027, with design completion in 2026 [1] Material Demand and Certification - M9 and M10 materials are projected to see explosive demand, with M9 CCL demand reaching millions of units by 2026 and increasing to 20-30 million units by 2027 alongside the Rubin platform [2] - M10 material certification has begun, with Nvidia requiring a loss factor (Df) of 0.0003. The competitive materials include PTFE (best electrical performance) and hydrocarbon resin + M10 filler, with PTFE outperforming M9 by 20%-30% [2] - M9 solutions have been confirmed, utilizing either "hydrocarbon resin + Q fabric" or "PTFE + fiberglass-free fabric," with a stable yield of 90% for M9 CCL, ready for mass production [2] Supply Chain and Pricing - The supply side is highly concentrated, with CTE fabric currently in severe shortage, priced at 120 RMB/kg, expected to rise further in 2026. New production capacity is anticipated to be released in the second half of 2026 [3] - Q fabric is primarily supplied by Asahi Kasei and domestic suppliers, with domestic prices 20%-30% lower than overseas [3] - Price increases for CCL are expected in 2025 due to rising costs of glass fabric and copper foil, with a projected 20%-30% increase in prices being passed down to end-users by April 2026 [3] PCB Market Dynamics - Due to the surge in PCB demand and value, existing suppliers are unable to meet capacity, prompting Nvidia to onboard new suppliers to ensure supply and reduce costs, with 2-4 suppliers per material number [4] - Key suppliers for LPU and CPU boards are identified, with a notable shift in market share towards new entrants like Jingwang Electronics and Dongshan Precision, while traditional players like Shenghong Technology see a decline in market share despite increased absolute order volumes [4] Copper Foil Specifications - Specifications for copper foil are being upgraded in line with material advancements, with M9 requiring HVP4 copper foil and M10 requiring HVP5/HVP6, with demand for HVP4 expected to reach 8,000-30,000 tons by 2027 [4] - Domestic manufacturers like Tongguan and Longdian Huaxin are accelerating the replacement of foreign suppliers due to price advantages [4] Market Potential - The market potential for CCL is significant, with GB300 cabinets requiring 50 CCLs and 60 PPs, while Rubin Ultra cabinets require 200 CCLs and 240 PPs. The value of core products is highlighted, with LPU boards valued at 20,000-30,000 RMB each and next-generation switch backplanes exceeding 800,000 RMB [5] - The global demand for M9 CCL is projected to reach 20-30 million units by 2027, corresponding to an area of over 20 million square meters, indicating a market size of several billion RMB [5] - Key beneficiaries across various segments are identified, including Shengyi Technology in CCL, Feilihua in electronic fabric, Jingwang Electronics in PCB manufacturing, and Tongguan Copper Foil in copper foil [5]
