Introduction to F4BM265
The F4BM series laminates are formulated by scientifically combining fiberglass cloth, polytetrafluoroethylene resin, and PTFE film. Compared to the previous F4B material, F4BM265 delivers improved electrical performance, characterized by a wider range of dielectric constants, reduced dielectric loss, increased insulation resistance, and enhanced stability. This material can effectively replace similar foreign products.
The F4BM and F4BME variants share the same dielectric layer but differ in copper foil combinations. F4BM is designed with electrodynamic (ED) copper foil, making it suitable for applications that do not require passive intermodulation (PIM) performance. In contrast, F4BME utilizes reverse-treated foil (RTF), providing superior PIM characteristics, more precise line control, and lower conductor loss.
Features of F4BM265
The F4BM265 material offers several key features that enhance its usability:
Dielectric Constant (Dk): 2.65 ±0.05 at 10 GHz
Dissipation Factor: 0.0013 at 10 GHz, 0.0018 at 20 GHz
Temperature Coefficient of Dielectric Constant (TCDK): -100 ppm/°C (temperature range: -55°C to 150°C)
CTE (Coefficient of Thermal Expansion):
X-axis: 14 ppm/°C
Y-axis: 17 ppm/°C
Z-axis: 142 ppm/°C (temperature range: -55°C to 288°C)
Thermal Conductivity: 0.36 W/mk
Moisture Absorption: 0.08%
These features make the F4BM265 material particularly suitable for high-frequency applications, ensuring low loss and enhanced dimensional stability.
Typical Applications
This PCB is well-suited for a variety of applications, including:
Microwave, RF, and Radar Systems: Ideal for high-frequency communication devices.
