Introducing our newly shipped PCB based on F4BM265, an advanced high-performance PCB developed by Wangling. Scientifically formulated and precisely pressed, F4BM265 combines fiberglass cloth, polytetrafluoroethylene (PTFE) resin, and PTFE film to deliver exceptional electrical performance and enhanced stability. With improved characteristics compared to F4B265, this laminate offers lower dielectric loss, increased insulation resistance, and enhanced stability, making it a viable alternative to similar foreign products for various applications.
Features:
- Impressive Electrical Performance:F4BM265 exhibits remarkable electrical properties, including a dielectric constant (Dk) of 2.65 at 10GHz, ensuring efficient signal transmission. With a dissipation factor of 0.0013 at 10GHz, it minimizes signal loss, enhancing overall performance.
-Enhanced Dimensional Stability:F4BM265 achieves precise control of the dielectric constant by adjusting the ratio of PTFE to fiberglass cloth, resulting in exceptional dimensional stability. It offers lower thermal expansion, improved temperature drift, and a slight increase in dielectric loss, ensuring reliable operation in demanding environments.
- Optimal Thermal Management: F4BM265 has a low coefficient of thermal expansion (CTE) of 14 ppm/°C (x-axis), 17 ppm/°C (y-axis), and 142 ppm/°C (z-axis) over a temperature range of -55°C to 288°C. This ensures stability and reliability, even in extreme temperature conditions.
- Excellent Moisture Resistance: With a moisture absorption rate of less than 0.08%, F4BM265 demonstrates high resistance to moisture, safeguarding the PCB's performance and longevity.
- Dependable Safety: F4BM265 meets UL-94 V0 flammability standards, complying with stringent safety regulations.
