The dielectric constant (Dk) of PCB materials varies with frequency and testing methods, highlighting the need for standardized measurement approaches, especially at millimeter wave frequencies, while differences between raw material and circuit-based tests can lead to divergent results due to anisotropy and testing setups.
The dielectric constant (Dk) of PCB materials varies with frequency and testing method, crucially impacting high-frequency applications like 5G and advanced driver assistance systems, where standardized measurement remains a challenge despite numerous testing methodologies available.
