What Makes RO4350B Material Stand Out?
Material Composition & Performance Balance
Rogers RO4350B materials are proprietary woven glass reinforced hydrocarbon/ceramics. They strike a unique balance: electrical performance close to PTFE/woven glass, while maintaining the manufacturability of epoxy/glass.
Processing & Cost Advantages
RO4350B laminates provide tight control on dielectric constant (Dk) and maintain low loss, all while using the same processing methods as standard epoxy/glass. They are available at a fraction of the cost of conventional microwave laminates and eliminate the need for special through-hole treatments or handling procedures required by PTFE-based materials. Plus, they’re UL 94 V-0 rated, making them suitable for active devices and high-power RF designs.
Thermal Stability Benefits
RO4350B’s thermal coefficient of expansion (CTE) offers key advantages:
Its expansion coefficient is similar to copper, ensuring excellent dimensional stability—critical for mixed dielectric multi-layer board constructions.
The low Z-axis CTE guarantees reliable plated through-hole quality, even in severe thermal shock applications.
With a Tg of >280°C (536°F), its expansion characteristics stay stable across the entire range of circuit processing temperatures.
Key Features
-Dielectric Constant of DK 3.48 +/-0.05 at 10GHz/23°C
-Dissipation Factor of 0.0037 at 10GHz/23°C
-Thermal Conductivity 0.69 W/m/°K
-X axis CTE of 10 ppm/°C, Y CTE of 12 ppm/°C, Z CTE of 32 ppm/°C
-High Tg value of >280 °C
-Low water absorption of 0.06%
-UL 94 V-0 rated
Benefits
-Ideal for multi-layer board (MLB) constructions
-Processes like FR-4 at lower fabrication cost
-Excellent dimensional stability
-Competitively priced
