PCB Dk/Df

Abstract With the rapid iteration of 5G-A, 6G pre-research, millimeter-wave radar, high-speed servers, AI computing hardware, autonomous driving electronics, and industrial RF equipment, high-speed PCB materials, high-frequency PCB laminates, and low-loss copper-clad laminates have become the core bottleneck of electronic product performance. Traditional standard FR4 laminates have high Dk and excessive Df, which easily lead…
