Key Features

1. Superior High-Frequency Performance

   • Ultra-low dielectric loss (Df ≤ 0.0018 @ 28 GHz) minimizes signal attenuation and energy dissipation.

   • Tight dielectric constant (Dk 2.0–3.5 ± 0.05) ensures consistent impedance matching and signal timing.

2. Enhanced Thermal Management

   • High thermal conductivity (up to 1.2 W/m·K) dissipates heat efficiently, reducing hot spots in dense circuits.

   • Low coefficient of thermal expansion (CTE) matches copper, preventing delamination and via cracking.

3. Excellent Reliability

   • Withstands high-temperature soldering processes and thermal cycling without degradation.

   • Low moisture absorption (<0.02%) maintains performance in humid environments.

4. Advanced Process Compatibility

   • Compatible with multilayer lamination, microvia drilling, and fine-line patterning processes.

   • Smooth surface profile (Ra ≤ 0.4 µm) enables precise deposition of thin-film components.
