RTduroid6002 PCB Multi Layer with White Solder Mask with Immersion Gold for FR Micorwave Antenna

Introduction:

RT/duroid 6002 is Rogers' premier PTFE-based ceramic composite laminate for high frequency applications. With its low dielectric constant and loss properties, it meets the strict electrical and mechanical requirements of complex microwave designs.

The dielectric constant of RT/duroid 6002 demonstrates excellent stability over a wide temperature range from -55°C to 150°C. This makes it well-suited for components like filters, oscillators and delay lines that demand stable electrical performance.

Now let's explore some of the impressive properties that make RT/duroid 6002 stand out:

To start, it has a dielectric constant of 2.94 at 10GHz and 23°C. This remains consistent from 8GHz to 40GHz, ensuring reliable signal transmission across operating frequencies.

The dissipation factor is extremely low at 0.0012 at 10GHz, resulting in minimal signal loss for optimal high frequency operation.

Thermal coefficient of dielectric constant is positive at +12 ppm/°C over 0°C to 100°C at 10GHz. This guarantees stability despite varying thermal environments.

Electrically, RT/duroid 6002 demonstrates high resistivity exceeding 106 Mohm-cm in volume and 107 Mohm for surface. This provides superior insulation with low leakage currents.

Mechanically, it has a tensile modulus over 800MPa in X and Y directions. The material withstands high levels of stress up to 6.9MPa with 7.3% ultimate strain.

In the Z-axis, compressive modulus exceeds 2400MPa, ensuring structural reliability under compressive loads. Moisture absorption is only 0.02%, minimizing detrimental effects of humidity on electrical properties.

Thermal conductivity of 0.6W/mK enables efficient heat dissipation in electronics. Coefficient of thermal expansion is moderately low, enhancing mechanical stability. Copper peel strength exceeds 1.5N/mm, allowing robust adhesion between copper and dielectric.

Flammability is V-0 per UL94 standards, resisting ignition and flame spread. The material also meets lead-free requirements, complying with environmental regulations.
