Rogers RO3006 2-Layer 5mil OSP PCB – High Frequency Microwave Applications
1. Introduction to Rogers RO3006 PCB
Rogers RO3006 laminates are ceramic-filled PTFE composites designed to offer exceptional electrical and mechanical stability, intended for use in commercial microwave and RF applications. The advanced circuit materials provide a stable dielectric constant (Dk) over a range of temperatures. This stability eliminates the step change in Dk that occurs for PTFE glass materials near room temperature.
RO3006 laminates have a dielectric constant of 6.15±0.15 and dissipation factor of 0.002 at 10 GHz. This 2-layer rigid PCB is constructed entirely with RO3006 as the core material, making it ideal for automotive radar, GPS antennas, satellite communication, and patch antenna applications.

7. Rogers RO3006 Material – Product Introduction
RO3000 high frequency circuit materials are ceramic-filled PTFE composites intended for use in commercial microwave and RF applications. This family of products was designed to offer exceptional electrical and mechanical stability at competitive prices. RO3000 series laminates are ceramic-filled PTFE based circuit materials with mechanical properties that are consistent regardless of the dielectric constant selected. This allows the designer to develop multilayer board designs that use different dielectric constant materials for individual layers, without encountering warpage or reliability problems.
RO3000 materials exhibit a coefficient of thermal expansion (CTE) in the X and Y axis of 17 ppm/°C. This expansion coefficient is matched to that of copper, which allows the material to exhibit excellent dimensional stability, with typical etch shrinkage (after etch and bake) of less than 0.5 mils per inch. The Z-axis CTE is 24 ppm/°C, which provides exceptional plated through-hole reliability, even in severe thermal environments.
