Core Material: F4BTM350 Advantage

Our PCB’s core strength lies in the F4BTM350 laminate—scientifically engineered by combining fiberglass cloth, nano-ceramic fillers, and polytetrafluoroethylene (PTFE) resin through strict pressing processes. Derived from theF4BM dielectric layer, this advanced material integrates high-dielectric, low-loss nano-ceramics to deliver a superior balance of properties:

1) Stable Dielectric Performance: Dk of 3.5±0.07 and dissipation factor of 0.0025 at 10GHz, ensuring minimal signal attenuation for high-frequency applications.

2) Exceptional Thermal Stability: CTE values of 10 ppm/°C (x-axis), 12 ppm/°C (y-axis), and 51 ppm/°C (z-axis) across -55°C to 288°C, plus a low Dk thermal coefficient (-60 ppm/°C from -55°C to 150°C), preventing warpage under extreme temperature fluctuations.

3) Reliable Insulation & Durability: Moisture absorption≤0.05%, UL-94 V0 flammability rating, and CTI >600V (Grade 0), ensuring long-term performance in harsh environments.

4) Optimized Conductivity: Paired with ED copper foil (ideal for non-PIM requirements), it offers precise line control and low conductor loss, outperforming standard PTFE laminates.
