Why Rogers RO4350B Stands Out
Rogers RO4350B is a game-changing material that bridges the gap between high-performance PTFE laminates and cost-effective epoxy/glass solutions. Here’s what makes it exceptional:
Unmatched Electrical Performance: With a tightly controlled dielectric constant (Dk) of 3.48 +/- 0.05 at 10 GHz/23°C and an ultra-low dissipation factor of 0.0037 at 10 GHz/23°C, RO4350B ensures superior signal integrity and minimal loss, even at high frequencies.
Thermal Excellence: A high glass transition temperature (Tg) of >280°C and a thermal conductivity of 0.69 W/m/°K make it ideal for high-power and high-temperature environments.
Dimensional Stability: Its CTE (coefficient of thermal expansion) closely matches that of copper (X: 10 ppm/°C, Y: 12 ppm/°C, Z: 32 ppm/°C), ensuring exceptional dimensional stability for multi-layer board constructions.
Cost-Effective Manufacturing: Unlike traditional PTFE materials, RO4350B can be processed using standard FR-4 methods, significantly reducing production costs without compromising quality.
