What is Rogers PCB?
Rogers PCB refers to PCBs made with advanced laminate materials from Rogers Corporation. Unlike standard FR-4 PCBs, which rely on epoxy resin and glass fiber, Rogers laminates—such as PTFE (Teflon), ceramic-filled composites, or hydrocarbon blends—deliver superior performance in high-frequency environments. These materials are engineered for minimal signal loss, stable dielectric properties, and robust thermal management, making them ideal for applications like 5G antennas, radar systems, and microwave circuits.
