F4BM300 PCB 2 Layer 1.524mm Immersion Tin Finished Board

Product Specification

In the ever-evolving landscape of electronic manufacturing, the demand for high-performance printed circuit boards (PCBs) has never been greater. Engineers and designers require materials that not only meet stringent performance criteria but also offer reliability and versatility for various applications.The F4BM300 PCB from Wangling—an innovative laminate that sets a new standard in the industry.Let's delve into the specific features, benefits, and applications of the F4BM300 PCB, showcasing why it is an essential choice for modern electronic designs.

Advanced Material Composition

The F4BM300 laminate is meticulously crafted from a scientifically formulated combination of fiberglass cloth, polytetrafluoroethylene (PTFE) resin, and PTFE film. This unique formulation enhances the electrical performance compared to its predecessor, the F4B300. The key advantages include lower dielectric loss, increased insulation resistance, and improved thermal stability. By replacing similar foreign products, the F4BM300 offers a competitive edge in both quality and cost-effectiveness.

Comparison with F4BME300

While the F4BM300 shares the same dielectric layer as the F4BME300, the two differ in their copper foil combinations. The F4BM300 utilizes Electrodeposited (ED) copper foil, making it suitable for applications that do not require Passive Intermodulation (PIM) performance. In contrast, the F4BME300 is paired with reverse-treated foil (RTF) copper foil, which provides excellent PIM performance, more precise line control, and reduced conductor loss. This flexibility allows engineers to choose the best laminate based on their specific application needs.

Electrical Performance

The F4BM300 boasts impressive electrical characteristics:
- Dielectric Constant (Dk): 3.0 at 10 GHz, ensuring efficient signal transmission.
- Dissipation Factor: 0.0017 at 10 GHz, minimizing energy loss.
- Thermal Coefficient of Dk: -80 ppm/°C, providing stability across temperature fluctuations.
- Moisture Absorption: ≤0.08%, ensuring reliability in humid environments.
- Flammability Rating: UL-94 V0, meeting stringent safety standards.
