Core Features of RO4534™ PCBs

• 1. Excellent Electrical Performance

  - Low Dielectric Constant and Dissipation Factor: RO4534™ boasts a dielectric constant (Dk) of 3.4 ± 0.08 and a dissipation factor (Df) as low as 0.0022 (2.5 GHz), significantly reducing energy loss and latency in signal transmission. This makes it particularly suitable for high-frequency applications in the millimeter-wave band, such as 5G and 24 GHz automotive radar.

  - Low Passive Intermodulation (PIM): Its copper foil surface treatment optimizes the smoothness of the copper-dielectric interface, significantly reducing PIM interference. This performance excels in applications such as base station antennas, with a typical PIM value of -157 dBc.

• 2. Good Physical and Thermal Stability
  
  - High Thermal Conductivity (0.6 W/m·K): Improves heat dissipation efficiency, ensuring stable operation in high-power scenarios. – Low Coefficient of Thermal Expansion (Z-axis CTE 46 ppm/°C): Matches the thermal expansion coefficient of copper foil, reducing the risk of deformation caused by temperature changes and ensuring the reliability of multilayer boards (MLBs).
  3. Processing Compatibility
  - RO4534™ is compatible with standard FR-4 processes, requiring no special via preparation or chemical processes, reducing manufacturing costs. It supports laser drilling and precision circuit design, meeting the stringent precision requirements of high-frequency circuits.
