Introduction
The F4BTMS series is an upgraded version of the F4BTM series. The material now incorporates a large amount of ceramics and utilizes ultra-thin and ultra-fine fiberglass cloth reinforcement. These enhancements have greatly improved the material's performance, resulting in a wider range of dielectric constants.
The incorporation of ultra-thin, ultra-fine fiberglass cloth reinforcement, along with a precise blend of special nanoceramics and polytetrafluoroethylene resin, minimizes electromagnetic wave interference, reducing dielectric loss and enhancing dimensional stability.
F4BTMS exhibits reduced anisotropy in the X/Y/Z directions, enabling higher frequency usage, increased electrical strength, and improved thermal conductivity.
Features
F4BTMS material offers a wide range of dielectric constants, providing flexible options from 2.2 to 10.2, while maintaining a stable value throughout.
Its dielectric loss is extremely low, ranging from 0.0009 to 0.0024, minimizing energy dissipation and improving overall system efficiency.
F4BTMS exhibits excellent temperature coefficient of dielectric constant. The TCDK with a DK value ranging from 2.55 to 10.2, remains within 100 ppm/℃.
The CTE values in the X and Y directions are between 10-50 ppm/°C , while in the Z direction, it is as low as 20-80 ppm/°C. This low thermal expansion ensures exceptional dimensional stability, enabling reliable hole copper connections.
F4BTMS demonstrates remarkable resistance to radiation, retaining stable dielectric and physical properties even after exposure to irradiation; and low outgassing performance, meeting the vacuum outgassing requirements for aerospace applications.
