F4BTMS255 Copper Clad Laminate: Aerospace-Grade High-Frequency Material
Taizhou Wangling Company presents the F4BTMS255, a premium PTFE-based laminate engineered for the most demanding high-frequency applications. As part of our advanced F4BTMS series, this material represents a significant technological breakthrough—combining ultra-thin, ultra-fine glass fabric reinforcement with homogeneous dispersion of specialty nano-ceramic fillers. The result is an aerospace-grade material that delivers exceptional electrical performance, dimensional stability, and reliability for mission-critical applications.
Material Technology
The F4BTMS255 incorporates several innovative features that set it apart from conventional PTFE laminates:
Electrical Performance
The F4BTMS255 features a dielectric constant (Dk) of 2.55 ±0.04 at 10 GHz, with identical design value ensuring predictable impedance control. The dissipation factor (Df) is exceptionally low:
This ultra-low loss performance extends usability to 40 GHz and beyond, with stable dielectric properties that support phase-sensitive applications.
The thermal coefficient of dielectric constant is -92 ppm/°C from -55°C to 150°C, ensuring stable electrical performance across a wide operating temperature range. Volume and surface resistivity both exceed 1 × 10⁸ MΩ, providing excellent insulation characteristics.
