Key Features of Rogers DiClad 870

DiClad 870 enhances the PCB’s performance with a range of standout features:

• Electrical Stability: Dielectric Constant (Dk) of 2.33 at 10 GHz and 1 MHz (50% RH), with a low dissipation factor of 0.0013 at 10 GHz and 0.0009 at 1 MHz—minimizing signal loss in high-frequency applications.

• Thermal Coefficient of Dielectric Constant (TcDK): -161 ppm/°C over the range of -10~140°C (10 GHz), ensuring stable electrical performance across temperature fluctuations.

• Mechanical and Environmental Resilience: Low moisture absorption (0.02%)—the lowest among PTFE-based composites—along with a copper peel strength of 14 lbs/in (10s @288°C), ensuring durability in harsh environments.

• Safety and Reliability: Arc resistance >180 seconds and UL 94-V0 flammability rating, enhancing safety in critical applications.

• Dimensional Stability: Coefficient of Thermal Expansion (CTE) of 17 ppm/°C (X-axis), 29 ppm/°C (Y-axis), and 217 ppm/°C (Z-axis), supporting consistent performance under thermal stress.

Benefits of DiClad 870

These features translate to critical advantages for the PCB:

• Lowest Moisture Absorption: Ensures long-term reliability in humid or moisture-prone environments.

• Stable Dk Over Frequency: Maintains consistent signal propagation across a wide range of operating frequencies, critical for multi-band systems.

• Reduced Insertion Loss: Low Dk supports wider line widths, minimizing signal attenuation and enhancing overall system efficiency.
