When selecting substrate materials for high-frequency printed circuit boards (PCBs), it is crucial to understand how the material's dielectric constant (DK) varies with frequency. For applications that demand high-speed signal transmission or precise control over characteristic impedance, attention must be paid to the dielectric loss (DF) and how it behaves under different frequency, temperature, and humidity conditions. In this article, HXD Circuits provides key insights into the behavior of high-frequency and high-speed PCB materials.
