Rogers RO4350B Material Introduction
Rogers RO4350B materials are proprietary woven glass reinforced hydrocarbon/ceramics that combine electrical performance close to PTFE/woven glass with the manufacturability of epoxy/glass. These laminates offer tight control over dielectric constant (Dk) and maintain low loss while utilizing the same processing methods as standard epoxy/glass materials. Available at a fraction of the cost of conventional microwave laminates, RO4350B does not require the special through-hole treatments or handling procedures needed for PTFE-based materials. Additionally, RO4350B laminates are UL 94 V-0 rated, making them suitable for active devices and high-power RF designs.
Key Material Features
| Feature | Specification/Description |
| Dielectric Constant (Dk) | 3.48 ± 0.05 at 10GHz/23°C |
| Dissipation Factor | 0.0037 at 10GHz/23°C |
| 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 |
| Glass Transition Temperature (Tg) | >280 °C |
| Water Absorption | 0.06% (low water absorption) |
| Flammability Rating | UL 94-V0 |
| Manufacturability | Compatible with standard epoxy/glass processing methods; no special through-hole treatments required |
