中金：AI PCB电镀铜粉耗材迎景气周期

Core Insights - The report from CICC indicates that AI-driven PCB products are upgrading towards high aspect ratio and multi-blind buried holes, leading to a surge in demand for copper powder consumables used in PCB electroplating, resulting in both volume and price increases that drive rapid profit growth in the industry, with strong long-term growth certainty and a short-term tight capacity situation indicating an upcoming boom cycle [1] Group 1 - AI PCBs are driving rapid profit growth in the copper powder processing industry, with copper balls and copper powder accounting for 6% and 13% of PCB costs respectively [2] - The thickness and layer count of AI PCBs are significantly increasing, with a geometric growth in the number of blind buried holes, leading to a rising trend in the proportion of copper powder used [2] - It is expected that by 2029, the proportion of PCB copper powder consumables in electroplating consumables will increase from the current 15% to over 27% [2] Group 2 - The industry is experiencing stable supply and rapidly growing demand, with signs of potential processing fee increases due to tight supply-demand dynamics before new capacities come online [2] - Japanese and Korean companies maintain a leading edge in product purity and particle size control in the copper powder sector, while domestic companies like Jiangnan New Materials and Taixing Smelting have capacities of 30,000 tons and 14,500 tons respectively [2] - New domestic production capacities exceeding 30,000 tons are expected to come online by the second half of 2026, but tight supply is anticipated until then [2] Group 3 - Project approval and qualification constraints lead to relatively long expansion cycles, with copper powder processing fees ranging from 8,400 to 10,400 yuan per ton [3] - The copper powder market is highly concentrated with few participants, and the main processing steps include smelting, ammonia evaporation, sintering, and powder screening [3] - The domestic equipment localization rate has significantly increased, but qualification approvals and expansion cycles may exceed one year [3]
