Introduction to F4BTMS Base Material
The F4BTMS series is an upgraded iteration of the F4BTM series, with technological advancements in material formulation and manufacturing techniques. By adding a substantial quantity of ceramics and reinforcing with ultra-thin, ultra-fine glass fiber cloth, the material’s performance has been significantly enhanced, and it offers a wider range of dielectric constants. It is a high-reliability material suitable for aerospace use and can serve as a substitute for similar foreign products.
Through the integration of a small amount of ultra-thin, ultra-fine glass fiber cloth and a large quantity of uniformly dispersed special nano-ceramics mixed with polytetrafluoroethylene resin, the material reduces the adverse impact of glass fiber on electromagnetic wave propagation. This leads to lower dielectric loss, improved dimensional stability, reduced X/Y/Z anisotropy, an expanded usable frequency range, enhanced electrical strength, and increased thermal conductivity. Furthermore, it possesses an excellent low coefficient of thermal expansion and stable dielectric temperature characteristics. The F4BTMS series is equipped with RTF low-roughness copper foil as standard, which lowers conductor loss and ensures excellent peel strength, and it is compatible with both copper and aluminum substrates.
