Introducing our newly shipped RF PCB, specifically designed for high-frequency applications and built using the advanced F4BM220 material. This cutting-edge printed circuit board combines polytetrafluoroethylene resin, polytetrafluoroethylene film, and glass fiber cloth through a meticulous manufacturing process. With its exceptional electrical performance, the F4BM220 RF PCB offers a wider range of dielectric constant, low dielectric loss, increased insulation resistance, and enhanced stability compared to its predecessor, F4B. It serves as an excellent substitute for similar foreign products.
Crafted with forward rotating ED copper foil for cladding, the F4BM220 RF PCB is specifically tailored for applications that do not require PIM (Passive Intermodulation) indicators, ensuring optimal performance for RF systems.
The F4BM220 series laminates employ a precise adjustment of the dielectric constant by modifying the ratio between polytetrafluoroethylene and glass fiber cloth. This technique not only achieves low loss but also enhances the dimensional stability of the material. As the dielectric constant increases, the proportion of glass fiber also increases, resulting in improved dimensional stability, a lower coefficient of thermal expansion, better temperature fluctuation performance, and increased dielectric loss.
