Advanced Copper Foil Development for Power Efficiency Enhancement

As Artificial Intelligence (AI) workloads drive unprecedented power demands in modern data centers, efficient power delivery has become a critical design priority. Traditional approaches such as increasing PCB copper thickness or adding layers are reaching physical and economic limits. This paper introduces an advanced copper foil (ADCF) solution that significantly reduces DC resistance compared to conventional Reverse Treated Foil (RTF) foils, thereby enhancing power efficiency. Through theoretical modeling, test vehicle validation, and system-level simulations, the study demonstrates up to 7.4% power loss reduction using ADCF. This translates into substantial electricity cost savings and carbon emission reductions in large-scale AI server deployments. By improving conductivity and minimizing energy loss, this innovation supports the broader goal of sustainable power efficiency in next-generation data center infrastructure.
