Dielectric Constant: 3.5 at 1.9 GHz, providing high signal integrity.
Dissipation Factor: Exceptionally low at 0.0018 at 1.9 GHz, reducing energy loss.
Dielectric Breakdown Strength: 41 kV, offering robust insulation.
Coefficient of Thermal Expansion (CTE): X CTE of 19 ppm/°C, Y CTE of 24 ppm/°C, Z CTE of 64 ppm/°C, ensuring stability across temperature variations.
Flammability Rating: UL-94 V0, indicating compliance with safety standards.

Benefits
The RF-35 PCB delivers numerous advantages:

Cost-Effective: Ideal for high-volume applications without compromising quality.
Excellent Peel Strength: Superior adhesion facilitates easier rework and assembly.
Low Moisture Absorption: Ensures reliable performance in humid conditions.
Enhanced Surface Smoothness: Improves performance in high-frequency applications.
