About Rogers RO4350B Material

The Rogers RO4350B material is a high-performance laminate made from woven glass-reinforced hydrocarbon/ceramic composites. It offers electrical characteristics comparable to PTFE-based laminates while maintaining the ease of processing associated with standard epoxy/glass materials. Its UL 94 V-0 flammability rating and high thermal conductivity make it ideal for high power RF designs and active devices.

Key Features of RO4350B:

• Dielectric Constant (Dk): 3.48 ± 0.05 at 10GHz/23°C.
• Dissipation Factor (Df): 0.0037 at 10GHz/23°C, ensuring minimal signal loss.
• Thermal Coefficient of Dk: +50 ppm/°C (ranging from -50°C to 150°C).
• Thermal Conductivity: 0.69 W/m/°K.
• Coefficient of Thermal Expansion (CTE): X-axis: 10 ppm/°C. Y-axis: 12 ppm/°C. Z-axis: 32 ppm/°C.
• High Glass Transition Temperature (Tg): >280°C.
• Low Water Absorption: 0.06%.
• Flammability: UL 94 V-0.

The RO4350B material is a proven solution for RF and microwave applications, providing high reliability and manufacturability without the need for special processing techniques like PTFE-based materials.
