Industry Standard

Currently, there is no industry standard test method for measuring dielectric properties of circuit board materials at frequencies greater than ~10 GHz. Various material vendors and test laboratories apply different approaches to determine these properties. It is common for these different approaches to yield varying values of key properties such as permittivity and loss tangent. The D-24C Task Group of IPC has developed this round-robin program to assess these various methods from the “bottom up” to determine if standardized methods can be agreed upon to provide the industry with more accurate and valid characteristics of dielectrics used in high-frequency and high-speed applications.
