TMM4 High Frequency PCB
Introduction:
Rogers TMM 4 is a thermoset microwave material designed to offer high plated-thru-hole reliability for strip-line and micro-strip applications. It is a composite material that combines the advantageous characteristics of ceramics, hydrocarbons, and thermoset polymers.
TMM 4 materials possess robust mechanical and chemical properties, providing many of the benefits found in both ceramic and traditional PTFE laminates. Unlike those materials, TMM 4 laminates do not require specialized production techniques. They are based on thermoset resins, ensuring reliable wire-bonding without the risk of pad lifting or substrate deformation.
Features
TMM4 laminates offer several key features as follows:
It has a dielectric constant of 4.50 +/- .045, providing stable electrical properties for high-frequency applications, and a dissipation factor of .0020 at 10GHz, indicating low signal loss and efficient signal transmission.
TMM4 has a thermal coefficient of Dk of 15ppm/°K, ensuring minimal changes in electrical performance with temperature variations.
The coefficient of thermal expansion is matched to copper, with values of x = 16 ppm/°K, y = 16 ppm/°K, and z = 21 ppm/°K. This compatibility reduces the risk of stress-related issues during thermal cycling.
TMM4 laminates have a high decomposition temperature (Td) of 425 °C TGA, ensuring their stability and reliability under elevated temperature conditions.
It exhibits a thermal conductivity of 0.7 W/mk, facilitating efficient heat dissipation in high-power applications.
TMM4 shows excellent resistance to moisture-related issues with moisture absorption rates of 0.07% for a thickness of 50mil and 0.18% for a thickness of 125mil.
