F4BME217 Copper Clad Laminate 0.1mm-12mm Thickness

Wangling's F4BME217 is a high-performance PTFE composite laminate engineered for demanding RF and microwave applications. Precision-formulated from woven fiberglass cloth, PTFE resin, and film, it delivers superior, consistent electrical properties.

This next-generation material significantly outperforms its predecessor, F4B220, offering lower dielectric loss, higher insulation resistance, and enhanced stability. It serves as a reliable, high-performance domestic substitute for comparable imported laminates.

Key Material Variants:
The core dielectric formulation is available in two copper foil configurations to suit specific application needs:

F4BM217: Clad with standard Electrodeposited (ED) copper foil. This is a cost-effective solution for standard high-frequency applications where low Passive Intermodulation (PIM) is not critical.

F4BME217: Clad with Reverse-Treated Foil (RTF) copper. This configuration provides superior low-PIM performance, enables more precise etching for fine-line circuits, and reduces conductor loss, making it ideal for high-precision designs.

Tailored Performance through Material Science:
The electrical and mechanical properties of F4BME217 are precisely tuned by adjusting the ratio of PTFE to fiberglass cloth within the composite. This allows for controlled dielectric constants while maintaining low loss characteristics and enhanced dimensional stability.

A higher dielectric constant is achieved by increasing the fiberglass content, which improves dimensional stability, lowers the thermal expansion coefficient, and reduces temperature drift.

This adjustment involves a balanced trade-off, as a higher fiberglass ratio may result in a marginal increase in dielectric loss.

This design flexibility enables engineers to select the optimal material grade for a perfect balance of electrical performance, mechanical robustness, and processing requirements.
