More About RO4534 Material

RO4534 is another high-performance material offered by Rogers Corporation for the fabrication of printed circuit boards (PCBs). Here are some key details about the RO4534 material:

Composition: RO4534 is a thermoset composite material. It consists of woven fiberglass reinforcement combined with a high-temperature resin system. This composition provides excellent mechanical strength, stability, and electrical performance.

Dielectric Constant (DK): The DK of RO4534 varies depending on the thickness of the laminate. Typically, it ranges from 3.48 to 3.52 at 10 GHz/23°C. The consistent and tightly controlled DK ensures predictable electrical performance in high-frequency applications.

Dissipation Factor: The dissipation factor of RO4534 is typically around 0.003 at 10 GHz/23°C. This low dissipation factor indicates minimal energy loss in the material, enabling superior signal integrity and reduced power loss in high-frequency circuits.

Thermal Conductivity: RO4534 has a thermal conductivity of 0.66 W/m/K at 50°C. While not as high as some other materials, it still provides effective heat dissipation for moderate power applications.

Moisture Absorption: RO4534 has a relatively low moisture absorption rate of approximately 0.03%. This moisture resistance helps maintain the material's electrical and mechanical stability, minimizing the impact of humidity on the PCB's performance.

Coefficient of Thermal Expansion (CTE): RO4534 exhibits a CTE of 17 ppm/°C in the X-axis and 17 ppm/°C in the Y-axis. These values represent how the material expands or contracts with temperature changes along different axes. The balanced CTE minimizes the risk of mechanical stress and ensures dimensional stability in PCB designs.

Flame Resistance: RO4534 is UL 94V-0 flame-rated, indicating its excellent flame resistance. This feature enhances the safety and reliability of PCBs constructed with this material.

RO4534 is commonly used in applications that require high-frequency performance and reliability, such as telecommunications, aerospace, and automotive industries. It is suitable for applications such as base station amplifiers, power amplifiers, filters, couplers, and other RF/microwave circuit designs where excellent electrical properties, mechanical strength, and thermal stability are vital.
