Material Attributes of Rogers TMM6

As a ceramic-thermoset polymer composite tailored for microwave applications, Rogers TMM6 possesses unique properties that form the foundation of the PCB’s high performance:

1. Electrical Performance

Dielectric Constant (Dk): 6.0 ± 0.08 at 10GHz, with tight tolerance to ensure predictable signal propagation—critical for designing precise RF/microwave components such as filters and couplers.

Dissipation Factor (Df): 0.0023 at 10GHz, ultra-low loss to minimize signal attenuation—maintains signal integrity even in long trace routes, which is essential for high-frequency communication systems.

Thermal Coefficient of Dk: -11 ppm/°K, minimizing Dk drift caused by temperature changes—ensures stable performance in environments with fluctuating temperatures (such as outdoor communication equipment or satellite systems).

2. Thermal & Mechanical Resilience

Decomposition Temperature (Td): 425°C (TGA), withstanding high temperatures generated by power dissipation (e.g., in power amplifiers) and reflow soldering processes—prevents material degradation under extreme heat.

Coefficient of Thermal Expansion (CTE): 18 ppm/K (x-axis), 18 ppm/K (y-axis), 26 ppm/K (z-axis), matching the CTE of copper—avoids delamination between copper layers and TMM6 core during thermal cycling, enhancing structural stability.

Thermal Conductivity: 0.72 W/mK, efficiently dissipating heat from high-power components—reduces thermal hotspots and extends the service life of sensitive RF devices.

Mechanical Strength: Resists creep and cold flow, maintaining dimensional stability under mechanical stress—suitable for rugged applications such as automotive GPS antennas or aerospace communication modules.

3. Fabrication & Application Advantages

Process Compatibility: Compatible with all common PCB manufacturing processes (including etching, drilling, and plating), eliminating the need for specialized production techniques—reducing manufacturing costs and lowering technical barriers.

Chemical Resistance: Resistant to process chemicals (such as etchants and cleaning agents), minimizing material damage during fabrication and reducing reject rates.

Wire-Bonding Reliability: Based on thermoset resin, enabling stable wire bonding for RF chips—ensures reliable high-frequency signal transfer between chips and the PCB, which is critical for microwave circuit performance.

Some Typical Applications:

- RF and microwave circuitry

- Power amplifiers and combiners

- Filters and coupler

- Satellite communication systems

- Global Positioning Systems Antennas

- Patch Antennas

- Dielectric polarizers and lenses

- Chip testers
