Introduction to RO3006
Rogers RO3006 laminates are ceramic-filled PTFE composites that offer exceptional electrical and mechanical stability. They are specifically designed for use in commercial microwave and RF applications. These advanced circuit materials provide a stable dielectric constant (Dk) over a range of temperatures, eliminating the step change in Dk that occurs for PTFE glass materials near room temperature.
Features of RO3006
-Ceramic-filled PTFE composites.
-Dielectric constant of 6.15+/- 0.15 at 10 GHz/23°C.
-Dissipation factor of 0.002 at 10 GHz/23°C, ensuring minimal signal loss.
-Td> 500°C, indicating high thermal resistance.
-Thermal Conductivity of 0.79 W/mK, facilitating efficient heat dissipation.
-Moisture Absorption of 0.02%, making it highly resistant to moisture-related issues.
-Coefficient of Thermal Expansion (-55 to 288 °C): X axis 17 ppm/°C, Y axis 17 ppm/°C, Z axis 24 ppm/°C, ensuring dimensional stability across a wide temperature range.
