Performance Characteristics

Electrical Properties
The RF-35 PCB features a dielectric constant of 3.5 at 1.9 GHz, ensuring minimal signal loss for high-frequency applications. Its low dissipation factor of 0.0018 enhances operational efficiency, while moisture absorption is just 0.02%, maintaining stability in various environments. Additionally, a dielectric breakdown voltage of 41 kV provides robust electrical reliability.

Mechanical Properties
This PCB exhibits excellent mechanical strength, with peel strength ratings exceeding 8.0 lbs/in (1.5 N/mm) for 1/2 oz. copper and over 10.0 lbs/in (1.8 N/mm) for 1 oz. copper. Flexural strength measures greater than 22,000 psi (152 N/mm2) lengthwise and over 18,000 psi (124 N/mm2) crosswise. Tensile strength is also high, at 27,000 psi (187 N/mm2) lengthwise and 21,000 psi (145 N/mm2) crosswise, ensuring durability throughout manufacturing processes.

Thermal Properties
The PCB offers a thermal conductivity of 0.24 W/m/K, effectively dissipating heat. Its coefficient of thermal expansion (CTE) ranges from 19-24 ppm/°C in the X-Y direction and 64 ppm/°C in the Z direction, indicating stability under temperature changes. This thermal resilience is crucial for maintaining structural integrity in diverse operational conditions.
