Modern server motherboards require predictable impedance, extremely low jitter, and stable multi-gigabit routing to support DDR5, PCIe 6.0, and high-density network interfaces. FR-4-class materials fail to provide consistent loss and dielectric stability. Megtron 7 PCB laminates supply ultra-low Df, tight dielectric tolerances, and high-temperature reliability suited for 8–64 GT/s environments. KKPCB adapts Megtron 7 PCB...
