F4BM265 Wangling PCB 3.0mm Laminate 2-layer F4BM High Frequency Circuit Board HASL Lead Free
Introduction
Wangling's F4BM265 laminates represent a significant advancement in PCB technology. These laminates are meticulously crafted using a scientific formulation that combines fiberglass cloth, polytetrafluoroethylene (PTFE) resin, and polytetrafluoroethylene film. Compared to its predecessor, F4B265, F4BM265 exhibits superior electrical performance, including lower dielectric loss, increased insulation resistance, and improved stability. Offering comparable performance to similar foreign products, F4BM265 is a versatile choice for a wide range of applications.
Dielectric Layer and Copper Foil Options
F4BM265 and F4BME265 share the same dielectric layer but differ in their copper foil combinations. F4BM265 employs ED copper foil, making it ideal for applications that do not require passive intermodulation (PIM) performance. On the other hand, F4BME265 is paired with reverse-treated foil (RTF) copper foil, delivering excellent PIM performance, precise line control, and lower conductor loss.
Controlled Dielectric Constant and Dimensional Stability
The ratio between polytetrafluoroethylene and fiberglass cloth in F4BM265 and F4BME265 allows for precise control of the dielectric constant. This precise control results in low loss and enhanced dimensional stability. A higher proportion of fiberglass corresponds to a higher dielectric constant, which contributes to better dimensional stability, lower thermal expansion coefficient, improved temperature drift, and a slight increase in dielectric loss.
Key Features of F4BM265
1)Dielectric Constant (Dk) of 2.65 at 10GHz:
F4BM265 exhibits a stable dielectric constant, ensuring reliable signal transmission and maintaining signal integrity in high-frequency applications.
2)Dissipation Factor of 0.0013 at 10GHz:
With an exceptionally low dissipation factor, F4BM265 minimizes signal loss and guarantees high-performance signal transmission.
3)Coefficient of Thermal Expansion (CTE)
x-axis: 14 ppm/°C
y-axis: 17 ppm/°C
z-axis: 142 ppm/°C
F4BM265 offers controlled CTE values along different axes, enabling thermal stability and reducing the risk of failure due to temperature variations.
4)Low Thermal Coefficient of Dk:
F4BM265 exhibits a low thermal coefficient of Dk, ensuring minimal signal distortion over a wide temperature range (-55°C to 150°C).
5)Moisture Absorption of ≤0.08%:
The low moisture absorption rate of F4BM265 enhances its reliability and performance in humid environments.
6)Flammability: UL-94 V0:
F4BM265 complies with UL-94 V0 flammability standards, providing excellent fire resistance and safety.
