Rogers is a type of high-frequency board produced by Rogers. 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. It is very suitable for high-speed electronic design, commercial microwave, and radio frequency applications. Its low water absorption is ideal for high-humidity applications, providing customers in the high-frequency board industry with the highest quality materials and related resources, which fundamentally enhance product quality.
