About F4BTM300 Laminate

F4BTM300 laminates are nano-ceramic/PTFE composites reinforced with glass fiber cloth, offering high dielectric constant stability, low loss tangent, and excellent thermal resistance. These laminates are specifically designed for aerospace, radar, and microwave applications and provide dimensional stability and enhanced signal performance.

Key Features of F4BTM300:

• Dielectric Constant (Dk): 3 ± 0.06 at 10GHz, providing precise impedance control.
• Dissipation Factor (Df): 0.0018 at 10GHz and 0.0023 at 20GHz, ensuring minimal signal loss.
• CTE (Coefficient of Thermal Expansion): X-axis: 15 ppm/°C, Y-axis: 16 ppm/°C, Z-axis: 72 ppm/°C
• Thermal Coefficient of Dk: -75 ppm/°C, ensuring phase stability over temperature ranges (-55°C to 150°C).
• Moisture Absorption: 0.05%, ideal for humid environments.
• Thermal Stability: Withstands up to 288°C, ensuring durability under extreme thermal conditions.
• Flammability: UL-94 V0, meeting industry safety standards.

F4BTM laminates are paired with reverse-treated RTF copper foil, reducing conductor loss, improving PIM (Passive Intermodulation), and enabling precise line control.

Benefits of F4BTM300-Based PCBs

The low dissipation factor (Df) and tight Dk tolerance ensure minimal signal distortion and consistent impedance control at high frequencies.

The low thermal coefficient of Dk and excellent thermal conductivity (0.64 W/mK) provide consistent performance across wide temperature ranges and enable efficient heat dissipation.

With a moisture absorption rate of 0.05%, the PCB remains stable in humid and harsh environments.

The material’s dimensional stability and compatibility with standard PCB processes ensure easy fabrication and high reliability.

The ENIG surface finish offers excellent solderability, corrosion resistance, and wire-bonding compatibility, making it ideal for high-reliability applications.

F4BTM300 laminates provide low insertion loss and minimal conductor loss, making them suitable for high-power and high-frequency applications.
