Wangling F4BTMS255 PCB 2-layer 60mil 1.524mm Thick F4BTMS Series Substrates Immersion Gold

Introduction

The F4BTMS255 2-layer rigid PCB represents a leap in high-performance circuit board technology, built around the upgraded F4BTMS PCB material series—an innovation that resolves key pain points in demanding applications. Unlike standard PCBs, it integrates nano-ceramic enrichment and ultra-fine glass fiber reinforcement to minimize electromagnetic (EM) wave interference, reduce dielectric loss, and ensure stability across extreme temperatures.

F4BTMS Material: The Foundation of Superior Performance

The F4BTMS PCB series is an advanced upgrade of the F4BTM PCB line, engineered via breakthroughs in material formulation and production. Its core advantages include:

1) Enhanced Composition: A blend of polytetrafluoroethylene (PTFE) resin, high-load uniformly distributed nano-ceramics, and ultra-thin/ultra-fine glass fiber cloth minimizes the negative impact of glass fiber on EM wave propagation—critical for RF/microwave signals.

2) Key Benefits: Reduced dielectric loss, improved dimensional stability, lower X/Y/Z anisotropy, and an expanded usable frequency range. It also features a low thermal expansion coefficient (CTE) and stable dielectric temperature characteristics.

3) Standard RTF Copper Foil: Equipped with Reverse Treating Foil (RTF) for low conductor loss and excellent peel strength, compatible with both copper and aluminum bases—ideal for high-power or weight-sensitive designs.

Key Electrical & Thermal Features of F4BTMS255

The PCB’s performance is defined by the F4BTMS255 material ’s industry-leading specs, making it ideal for high-frequency and extreme-environment applications:

1) Dielectric Constant (Dk): 2.55±0.04 at 10GHz (low, stable Dk minimizes signal delay).

2) Dissipation Factor (Df): 0.0012 at 10GHz, 0.0013 at 20GHz (ultra-low loss for high-frequency signals).

3) Thermal Stability: CTE (Coefficient of Thermal Expansion) of 15 ppm/°C (x-axis), 20 ppm/°C (y-axis), 80 ppm/°C (z-axis) across -55°C to 288°C—prevents warping in temperature swings.

4) Low Dk Temperature Coefficient: -92 ppm/°C from -55°C to 150°C (ensures consistent signal performance in harsh environments).

5) Safety & Durability: UL-94 V0 flammability rating and 0.025% moisture absorption (resists corrosion and reliability risks in humid conditions).
