Core Viewpoint - The PCB industry is experiencing a growth cycle driven by AI, with increasing demand for high aspect ratio and multi-blind buried hole PCBs, leading to a surge in copper powder consumption and profitability in the industry [2][5][20]. Group 1: AI PCB and Copper Powder Demand - AI PCBs are driving the demand for copper powder, with the proportion of copper powder in PCB electroplating materials expected to rise from 15% to over 27% by 2029 [5]. - The processing fee for copper powder is 4-5 times that of copper balls, indicating a significant potential for profit growth in the copper powder industry [5][28]. - The demand for copper powder is expected to increase due to the rising complexity and requirements of AI PCBs, which necessitate higher copper thickness and more intricate plating processes [24][25]. Group 2: Supply and Production Dynamics - The supply of copper powder is currently tight, with domestic producers like Jiangnan New Materials and Guanghua Technology leading the market, while Japanese and Korean companies maintain technological advantages [6][33]. - The production capacity of domestic manufacturers is expected to increase significantly, with over 30,000 tons of new capacity anticipated by 2026 [5][38]. - The approval process for project qualifications and the relatively long expansion cycle may limit rapid capacity increases in the short term [6]. Group 3: Technological Advancements and Market Trends - The transition from copper balls to copper powder is becoming a trend due to the latter's superior performance in high-end PCB applications, particularly in terms of purity and stability [27][29]. - The shift towards pulse plating technology in PCB manufacturing is addressing the challenges of uniformity and filling capabilities in high aspect ratio designs [26]. - The increasing complexity of HDI PCBs requires advanced materials and processes, with copper powder emerging as a critical component in meeting these demands [22][24]. Group 4: Economic Implications and Market Positioning - The economic model for copper powder is based on a higher processing fee compared to copper balls, reflecting its value in high-end applications [28][29]. - The market for high-end copper powder is currently dominated by foreign companies, but domestic firms are rapidly advancing in technology and production capabilities, creating opportunities for local replacements [28][36]. - The profitability of copper powder is expected to improve as demand increases and supply tightens, with potential for higher margins in the future [38].
