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.
