RO4350B hydrocarbon ceramic laminates are specially engineered to deliver exceptional high-frequency

performance while maintaining cost-effective circuit fabrication. As operating frequencies increase beyond

500 MHz, the selection of suitable laminates for designers becomes limited. However, RO4350B offers the

necessary properties for designing RF microwave circuits, matching networks, and controlled impedance

transmission lines.

Thanks to its low dielectric loss, RO4350B is ideal for applications where higher operating frequencies would

traditionally limit the use of conventional circuit board materials. This makes it a versatile choice for demanding

high-frequency environments.

Temperature Coefficient of Dielectric Constant: RO4350B exhibits one of the lowest coefficients

of dielectric constant among circuit board materials, ensuring stability over a wide frequency range.

Thermal Coefficient of Expansion (CTE): The material's CTE offers significant advantages for PCB

designers. Its expansion coefficient is similar to copper, leading to excellent dimensional stability

crucial for mixed dielectric multi-layer board constructions.

Low Z-axis CTE: The low Z-axis CTE of RO4350B ensures reliable plated through-hole quality,

even under severe thermal shock conditions, enhancing the overall durability of the PCB.

Glass Transition Temperature (Tg): With a Tg exceeding 280°C, RO4350B maintains stable expansion

characteristics across the entire range of PCB processing temperatures, contributing to the material's

reliability and performance during manufacturing processes.
