4. Rogers RO3006 Substrate: Introduction, Features & Benefits
4.1 Introduction to Rogers RO3006
Rogers RO3006 laminates are high-performance ceramic-filled PTFE composites developed to deliver outstanding electrical and mechanical stability. A key advantage is their stable dielectric constant (Dk) across a wide temperature range, which eliminates the typical step change in Dk that affects standard PTFE glass materials near room temperature. This characteristic ensures consistent performance, making it a preferred choice for demanding microwave and RF systems.
