RO3006 PCB 2-Layer 5mil: High-Frequency Ceramic-Filled PTFE Laminates for Automotive Radar and Wireless Communication Systems

1.Introduction of RO3006

Rogers RO3006 laminates are ceramic-filled PTFE composites engineered to deliver outstanding electrical and mechanical stability for commercial microwave and RF applications. These advanced circuit materials maintain a consistent dielectric constant (Dk) across a wide temperature range, effectively eliminating the step change in Dk commonly seen with PTFE glass materials near room temperature.

Dissipation factor of 0.002 at 10 GHz/23°C
Thermal degradation temperature greater than 500°C
Thermal conductivity of 0.79 W/mK
Moisture absorption of 0.02%
Coefficient of thermal expansion (from -55 to 288 °C): X axis 17 ppm/°C, Y axis 17 ppm/°C, Z axis 24 ppm/°C

3. Benefits

Uniform mechanical properties across various dielectric constants, making it ideal for multi-layer board designs and compatible with epoxy glass multi-layer board hybrid constructions.
Low in-plane expansion coefficient that matches copper, ensuring reliable surface-mounted assemblies and excellent dimensional stability, particularly in temperature-sensitive applications.
Economical laminate pricing due to a volume manufacturing process.
