Rogers PCB is a type of high-frequency board that raw material is produced by Rogers company. It is different from the conventional PCB board—epoxy resin (FR4). It has no glass fiber in the middle and uses a ceramic base as the high-frequency material. Rogers has superior dielectric constant and temperature stability. Its dielectric constant thermal expansion coefficient is very consistent with copper foil, which can be used to improve the deficiencies of PTFE substrates.

Rogers PCB materials are available in several different formulations, each with its own unique set of properties and characteristics. Some of the most common formulations and main advantages are as follows:

Rogers RO4000 series: A high-frequency laminate material with low dielectric loss and low moisture absorption.

Rogers RO3000 series: A high-frequency laminate material with low loss tangent and excellent dimensional stability.

Rogers RT/duroid series: A high-frequency material with high thermal conductivity and low loss tangent.

Rogers TMM series: A high-thermal conductivity material with low dielectric loss and high thermal stability.
