Introduction to Rogers TMM4 Base Material
Rogers TMM4 is a thermoset microwave material composed of ceramic, hydrocarbon, and thermoset polymer composite. It is specifically designed for high plated-thru-hole reliability in strip-line and micro-strip applications, integrating the advantages of both ceramic and traditional PTFE laminates without the need for specialized production techniques. As a thermoset resin-based laminate, TMM4 ensures reliable wire-bonding performance without pad lifting or substrate deformation, making it ideal for high-frequency and high-reliability applications.
Key Features of Rogers TMM4 Material
| Key Features of Rogers TMM4 Material | Specifications & Descriptions |
| Dielectric Constant (Dk) | 4.50 +/- 0.045 (stable and precise for signal transmission) |
| Dissipation Factor | 0.0020 at 10GHz (low loss, suitable for high-frequency applications) |
| Thermal Coefficient of Dk | 15 ppm/°K (stable dielectric performance across temperature variations) |
| Coefficient of Thermal Expansion (CTE) | Matched to copper; x=16 ppm/°K, y=16 ppm/°K, z=21 ppm/°K (reduces thermal stress and improves reliability) |
| Decomposition Temperature (Td) | 425 °C (TGA) (high thermal stability) |
| Thermal Conductivity | 0.7 W/mk (effective heat dissipation) |
| Moisture Absorption | 0.07% - 0.18% (low moisture absorption, ensuring performance in humid environments) |
| Available Thickness Range | 0.0015 to 0.500 inches (+/- 0.0015”) (flexible for different design requirements) |
