Wangling's F4BM265 High-Frequency PCB: Unleashing Enhanced Performance

The F4BM265 laminates from Wangling are meticulously formulated by combining fiberglass cloth, polytetrafluoroethylene (PTFE) resin, and PTFE film. These laminates offer improved electrical performance when compared to F4B265, making them a preferred choice for high-frequency applications. In this blog post, we will delve into the features, construction details, and typical applications of Wangling's F4BM265 high-frequency PCB.

Features of F4BM265:

• A dielectric constant (Dk) of 2.65 at 10GHz ensures reliable signal transmission.
• With a low dissipation factor of 0.0013 at 10GHz, energy loss is minimized.
• Controlled thermal expansion coefficients (CTE) of 14 ppm/°C (x-axis), 17 ppm/°C (y-axis), and 142 ppm/°C (z-axis) from -55°C to 288°C contribute to dimensional stability.
• A low thermal coefficient of Dk at -100 ppm/°C from -55°C to 150°C maintains consistent performance across temperature variations.
• Moisture absorption is limited to ≤0.08%, providing long-term stability even in humid conditions.
• The PCB holds a flammability rating of UL-94 V0, ensuring compliance with safety standards.
