The F4BTMS220 Advantage

What truly sets the F4BTMS220 high frequency PCB apart is its core material—the F4BTMS PCB series, an upgraded iteration of the proven F4BTM platform. This material represents a technological leap, achieved through innovative formulation: a synergistic blend of polytetrafluoroethylene resin, high-load nano-ceramics, and ultra-thin glass fiber cloth. This unique composition solves two critical industry challenges: minimizing glass fiber-induced electromagnetic interference and reducing dielectric loss, making it ideal for microwave and RF applications.

Key Features of the F4BTMS220 Material:

1)Exceptional Signal Integrity: A stable Dielectric Constant (Dk) of 2.2±0.02 @ 10 GHz ensures predictable performance across the board.

2)Ultra-Low Loss: An incredibly low Dissipation Factor (Df) of 0.0009 @ 10 GHz (0.001 @ 20 GHz) minimizes signal attenuation, making it perfect for high-speed and high-frequency designs.

3)Superior Thermal & Dimensional Stability: A low thermal coefficient of Dk (-130 ppm/°C) and controlled CTE (X: 40, Y: 50, Z: 290 ppm/°C) ensure stable electrical performance across a wide temperature range (-55°C to 288°C).

4)High Reliability: The material is rated UL 94 V-0 and exhibits extremely low moisture absorption (0.02%), guaranteeing performance and longevity in harsh environments.

5)Low Profile & High Strength: The use of ultra-fine materials allows for a remarkably thin and rigid 5mil core without sacrificing mechanical integrity.

Typical Applications

The F4BTMS220 2-layer PCB is the preferred choice for:

• Aerospace equipment and cabin systems
