For almost 50 years, the electronic design industry has been searching for the Holy Grail of dielectric measurement techniques, resulting in 18 different IPC standards for measuring dielectric properties and several more approaches, including several “bootleg” operations that are not part of IPC.

Employing accurate material parameters in PCB design is critical to electrical performance, ensuring both signal and power integrity. PCB laminate manufacturers publish construction tables with resin-content and permittivity (Dk, Df), but how do electronic designers know that they have an “apples-to-apples” comparison across multiple laminate systems, constructions, and data sources?

In this presentation, we will discuss the history of the search for the Holy Grail laminate characterization method, where we are today, as well as implications for signal integrity in high-speed PCB designs going forward.
