F4BME High Frequency PCB
Introduction
These series laminates are made by scientifically formulating and strictly pressing a combination of fiberglass cloth, polytetrafluoroethylene resin, and polytetrafluoroethylene film. Its electrical performance is improved compared to F4B, mainly due to a wider range of dielectric constants, lower dielectric loss, increased insulation resistance, and improved stability. It can replace similar foreign products.
F4BME and F4BM have the same dielectric layer but different copper foil combinations: F4BME is paired with reverse-treated foil (RTF) copper foil, offering excellent PIM performance, more precise line control, and lower conductor loss. F4BM is paired with ED copper foil, suitable for applications without PIM requirements.
By adjusting the ratio between polytetrafluoroethylene and fiberglass cloth, F4BM and F4BME achieve precise control of the dielectric constant, providing low loss and enhanced dimensional stability. A higher dielectric constant corresponds to a higher proportion of fiberglass, resulting in better dimensional stability, lower thermal expansion coefficient, improved temperature drift, and a slight increase in dielectric loss.
