Parameters of Rogers RT/duroid® 5880 High-Frequency Laminate
RT/duroid® 5880 high-frequency laminate is a polytetrafluoroethylene (PTFE) glass fiber-reinforced material. These microfibers are randomly distributed within the material, providing maximum strength enhancement for circuit application and production processes.
These high-frequency materials possess the lowest dielectric constant among similar materials. Their extremely low dielectric loss makes them highly suitable for high-frequency, broadband applications that require minimized dispersion and loss. Additionally, the extremely low moisture absorption rate of RT/duroid® 5880 makes it an ideal choice for applications in high-humidity environments.
RT/duroid 5880 can be easily cut into the desired shapes and is resistant to erosion from all solutions and reagents used during etching and plated-through-hole processes. Both RT/duroid 5870 and 5880 laminates feature the lowest dielectric loss among reinforced PTFE materials, along with low moisture absorption rates, isotropy, and minimal variation in electrical properties with frequency.
To meet the increasingly stringent requirements for substrates in high-frequency circuit design, Rogers has introduced a new generation of high-frequency laminate, RT/duroid® 5880. Manufactured using PTFE glass fiber-reinforced material, the microfibers within the board are randomly distributed, ensuring exceptional strength requirements during circuit application and production processes. Compared to similar materials currently on the market, RT/duroid® 5880 has the lowest dielectric constant, measuring 2.20±0.02 under the 10GHz IPC-TM 2.5.5.5 standard.
Meanwhile, the dielectric loss of the board, measured under the same standard, is only 0.0009. Its extremely low dielectric loss makes it highly suitable for high-frequency and broadband applications that require minimized dispersion and loss, supporting maximum frequencies up to the Ku band and even higher. Additionally, RT/duroid® 5880 has an extremely low moisture absorption rate of only 0.02%, making it an ideal choice for high-humidity environment applications.
RT/duroid 5880 can be easily cut into the desired shapes, perfectly adapting to the requirements of various cavity structures for printed circuit boards in high-frequency applications. Furthermore, as a high-frequency laminate, RT/duroid 5880 supports an electroplated copper thickness ranging from 8 to 70μm. It is also resistant to erosion from various acid-base reagents used during processing and can withstand various high- and low-temperature processing procedures. RT/duroid 5870 features the lowest dielectric loss among reinforced PTFE materials, low moisture absorption rates, isotropy, and minimal variation in electrical properties with frequency, making it suitable for commercial aviation telephone circuits, microstrip and stripline circuits, millimeter-wave applications, military radar systems, missile guidance systems, and point-to-point digital radio antennas.
