Summary of Conference Call on Power PCB Industry Industry Overview - The focus is on the power PCB (Printed Circuit Board) market, which is anticipated to experience strong inflation and high growth in the future [1] - The concept of power PCB includes primary, secondary, and tertiary power PCBs, with secondary and tertiary being the core growth areas [1] Key Points - Primary Power PCB: Refers to AC/DC power PCBs that can carry higher currents through processes like gold finger technology, but there are no fundamental changes in size or structure [1] - Secondary Power PCB: Utilizes heavy copper and HDI (High-Density Interconnect) technology to ensure efficient current distribution and stable power supply. Specifications include 12-30 layers, thickness of 3-5mm, and 4-5 ounces of heavy copper technology combined with HDI, forming standardized modules [1] - Tertiary Power PCB: Represents the core changes in the current industrial trend, requiring complex embedded, HDI, and Msap (Modified Semi-Additive Process) technologies, marking the highest level of miniaturization in power PCBs [1] Market Potential - The market for power PCBs is expected to grow rapidly alongside the increasing power consumption of AI chips. For instance, Google's past unit value was around 0.5 yuan per watt, while AMD's was approximately 0.7-0.8 yuan per watt. Future advancements in PCB technology by companies like NVIDIA may further increase this unit value [2] - The power consumption of chips is significant, with the NVRubinUltra series reaching 3600W and the Feynman architecture potentially exceeding 5000W [2]
