Wangling F4BME217 2-Layer 1.3mm Bare Copper PCB – Microwave & RF Applications1. Introduction to Wangling F4BME217 PCB 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. F4BME217 is 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. This 2-layer rigid PCB is constructed entirely with Wangling F4BME217 as the core material, making it ideal for demanding microwave, RF, radar, and satellite communication applications.

Wangling F4BME217 Low-Loss PTFE Composite – Product Introduction 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. 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. F4BME217 is 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.
