F4BTMS Introduction

The F4BTMS series is an upgraded version of the F4BTM series. It has achieved a technological breakthrough in material formulation and manufacturing processes. Enriched with a significant amount of ceramics and reinforced with ultra-thin and ultra-fine glass fiber cloth, it shows substantial improvements in material performance and a broader range of dielectric constants. As a high-reliability material suitable for aerospace applications, it can replace similar foreign products.

By incorporating a small amount of ultra-thin and ultra-fine glass fiber cloth and a large amount of uniformly distributed special nano-ceramics mixed with polytetrafluoroethylene resin, the negative effects of glass fiber on electromagnetic wave propagation are minimized. This leads to reduced dielectric loss, enhanced dimensional stability, and decreased X/Y/Z anisotropy of the material. It also increases the usable frequency range, improves electrical strength, and enhances thermal conductivity. Additionally, the material exhibits an excellent low thermal expansion coefficient and stable dielectric temperature characteristics.

The F4BTMS series comes with RTF low roughness copper foil as a standard feature, which reduces conductor loss and provides excellent peel strength. It can be used with either copper or aluminum bases.
