   • Dielectric Constant (Dk): Range of values tailored for specific applications, typically between 3.27 and 12.
   • Low Dielectric Loss (Df): Ensures high efficiency at microwave frequencies.
2. Thermal Reliability:
   • High thermal conductivity for efficient heat dissipation.
   • Minimal dimensional changes with temperature fluctuations.
3. Mechanical Stability:
   • Uniform mechanical properties for consistent performance.
   • Resistant to creep and mechanical deformation.
4. Ease of Fabrication:
   • Compatible with standard PCB processing techniques, including drilling, routing, and metallization.
   • Excellent bond strength for multilayer assemblies.
5. Environmental Resistance:
   • Low moisture absorption.
   • Long-term reliability in harsh environmental conditions.
