F4BM220 PCB Double-Sided 0.8mm Substrate Immersion Gold

Product Specification

We're excited to introduce our newly shipped PCB : a high-performance, double-sided PCB built around the exceptional F4BM220 laminate. This isn't just another PCB; it's a meticulously engineered solution designed to meet the ever-increasing demands of RF, microwave, and high-speed digital applications.

The Heart of the Matter: F4BM220 Laminate

The foundation of this PCB's performance lies in the F4BM220 laminate from Wangling. This material represents a significant step forward compared to traditional PTFE-based laminates. It's crafted through a precise process of combining fiberglass cloth, polytetrafluoroethylene (PTFE) resin, and PTFE film. The result is a laminate with superior electrical characteristics, including:

Lower Dielectric Loss: Minimizing signal attenuation and maximizing power transfer efficiency. This is crucial for sensitive RF and microwave applications. A dissipation factor of just .001 at 10GHz ensures minimal signal degradation.

Increased Insulation Resistance: Enhancing reliability and preventing signal leakage, even in demanding environments.

Enhanced Stability: Maintaining consistent performance over a wide range of temperatures and frequencies.

What truly sets F4BM220 apart is the meticulous control over its dielectric properties. By carefully adjusting the ratio of PTFE and fiberglass cloth, we achieve a dielectric constant (Dk) of 2.2±0.04 at 10GHz. This precise control allows for accurate impedance matching and predictable circuit behavior, simplifying the design process and improving overall system performance.

Furthermore, the material exhibits excellent dimensional stability, characterized by low CTE values (25 ppm/°C on the x-axis, 34 ppm/°C on the y-axis, and 240 ppm/°C on the z-axis from -55°C to 288°C) and a low thermal coefficient of Dk (-142 ppm/°C from -55°C to 150°C). This ensures that the PCB maintains its structural integrity and electrical performance even under extreme temperature variations.

Construction and Manufacturing Excellence

Beyond the superior base material, this PCB benefits from a carefully optimized design and manufacturing process:
