RF Circuit Board - Rogers 5880 PCB

The Rogers RT/duroid 5880 PCB is made of polytetrafluoroethylene glass fiber reinforced material. These microfibers are randomly distributed within the material, providing excellent strength enhancement effects for circuit design and production processes.

Rogers 5880 PCB have the lowest dielectric constant among similar products, and their extremely low dielectric loss characteristics make them particularly suitable for high-frequency, wideband applications that require minimal dispersion and loss. In addition, the extremely low moisture absorption rate of the Rogers 5880 circuit board makes it an ideal choice for applications in high-humidity environments.

The Rogers 5880 PCB is easy to cut into the desired shape and can resist corrosion from various solutions and reagents used in processes such as etching and through-hole plating. The R Rogers 5880 PCB board not only has the lowest dielectric loss and low moisture absorption rate among polytetrafluoroethylene materials but also has the characteristics of isotropy and minimal electrical performance variation with frequency.

In order to meet the increasingly stringent requirements of high-frequency circuit design for board, Rogers 5880 is made of polytetrafluoroethylene glass fiber reinforced material, with randomly distributed internal microfibers, ensuring high strength requirements for board during circuit application and production processes.

According to the 10GHz IPC-TM 2.5.5.5 standard measurement, the dielectric constant of Rogers 5880 PCB is 2.20 ± 0.02. At the same time, measured under the same standard, the dielectric loss of 5880 PCB board is only 0.0009. This extremely low dielectric loss characteristic makes it very suitable for high-frequency and wideband applications that require minimizing dispersion and loss. The highest supported frequency can reach Ku band or even higher.

The Rogers 5880 PCB has an extremely low moisture absorption rate of only 0.02%, making it an ideal choice for applications in high humidity environments.

The Rogers 5880 PCB can perfectly adapt to the shape requirements of various cavity structures for PCB printed circuit board in high-frequency applications. As a high-frequency circuit board, the RT5880 PCB supports a thickness range of 8-70um for electrodeposited copper, and can resist the erosion of various acidic and alkaline reagents used during processing, as well as the tests of various high and low temperature processing procedures.

Rogers 5880 PCB also has the lowest dielectric loss, low moisture absorption rate, and excellent isotropy among polytetrafluoroethylene materials, and its electrical performance changes very little with frequency. This enables RT/duroid 5880 to demonstrate outstanding performance in commercial aviation telephone circuits, microstrip and strip line circuits, millimeter wave applications, military radar systems, missile guidance systems, and point-to-point digital radio antennas.
