F4BTMS1000 PCB High-Performance 2-Layer Rigid PCB for Aerospace Applications

1. F4BTMS Introduction

The F4BTMS series is an advanced version of the F4BTM series, featuring significant improvements in material formulation and manufacturing processes. This material integrates a high percentage of ceramics and ultra-thin glass fiber cloth, enhancing performance and offering a wider range of dielectric constants. It is particularly suitable for aerospace applications and can replace similar foreign products.

The incorporation of ultra-thin glass fiber and uniformly distributed special nano-ceramics mixed with polytetrafluoroethylene resin minimizes the negative effects of glass fiber on electromagnetic wave propagation, reducing dielectric loss and enhancing dimensional stability. This innovation increases the usable frequency range, improves electrical strength, and enhances thermal conductivity while exhibiting low thermal expansion and stable dielectric characteristics.

The F4BTMS series features RTF low roughness copper foil, which reduces conductor loss and provides excellent peel strength. It is compatible with both copper and aluminum bases.
