Materials
In the ever-evolving world of high-frequency electronics, the
demand for advanced materials that deliver superior performance,
reliability, and versatility is growing rapidly. Enter the F4BTMS
series, an upgraded version of the F4BTM series, designed to meet
the rigorous demands of aerospace, RF, and microwave applications.
With groundbreaking advancements in material formulation and
manufacturing processes, the F4BTMS series sets a new standard for
high-frequency PCB materials.
What Makes the F4BTMS Series Stand Out?
The F4BTMS series represents a significant leap forward in material
technology. By incorporating a unique blend of ultra-thin,
ultra-fine glass fiber cloth and special nano-ceramics mixed with
polytetrafluoroethylene resin, this material achieves exceptional
performance characteristics:
- Minimized Dielectric Loss: The optimized composition reduces the negative effects of glass
fiber on electromagnetic wave propagation, ensuring lower
dielectric loss and improved signal integrity.
- Enhanced Dimensional Stability: The material exhibits excellent dimensional stability with low
X/Y/Z anisotropy, making it ideal for high-precision applications.
- Wide Range of Dielectric Constants: The enriched ceramic content allows for a broader range of
dielectric constants, catering to diverse design requirements.
- Superior Thermal and Electrical Properties: With improved thermal conductivity, low thermal expansion, and
stable dielectric temperature characteristics, the F4BTMS series
excels in demanding environments.
- High Reliability: Designed for aerospace applications, this material is a reliable
alternative to similar foreign products.
The F4BTMS series comes standard with RTF low roughness copper
foil, which reduces conductor loss and ensures excellent peel
strength. It is compatible with both copper and aluminum bases,
offering flexibility for various applications.
