Rogers RT/duroid® 5880 high-frequency laminate?
What are the characteristics of Rogers RT/duroid® 5880 high-frequency laminate?
Rogers RT/duroid® 5880, as a polytetrafluoroethylene (PTFE) glass fiber-reinforced material, possesses the following remarkable characteristics:
1. Excellent Electrical Properties
- Extremely Low Dielectric Constant: Measured at just 2.20±0.02 under the 10GHz IPC-TM 2.5.5.5 standard, this characteristic helps reduce signal propagation delay and enhances signal transmission speed and efficiency, making it highly suitable for high-frequency applications.
- Extremely Low Dielectric Loss: With a dielectric loss factor of only 0.0009 under the same standard, the low-loss characteristic ensures minimal energy loss during signal transmission, maintaining signal integrity and strength. It is ideal for high-frequency, broadband applications requiring minimized dispersion and loss.
- Stable Electrical Performance: RT/duroid® 5880 maintains consistent electrical performance across a wide frequency range, ensuring the stability and reliability of signal transmission.
2. Outstanding Physical Properties
- Low Moisture Absorption Rate: With a moisture absorption rate of only 0.02%, RT/duroid® 5880 is exceptionally well-suited for use in high-humidity environments, such as outdoor communication equipment or marine applications. The low moisture absorption rate helps prevent changes in material properties due to moisture absorption, thereby maintaining the performance stability of the circuit board.
- High Strength Reinforcement: Reinforced with glass fibers, the randomly distributed microfibers within the material provide additional strength enhancement during circuit production and processing. This reinforcement ensures that the material can withstand certain mechanical pressures without breaking or deforming during circuit manufacturing and application.
3. Good Mechanical Properties
- Easy Processing: RT/duroid® 5880 is easily cut into the desired shapes, accommodating the diverse requirements for printed circuit board shapes in high-frequency applications. It also supports a thickness range of 8 to 70 micrometers for electroplated copper, offering flexibility in circuit board manufacturing.
- Chemical Resistance: The material is resistant to erosion from all solutions and reagents used during etching and plated-through-hole processes, making RT/duroid® 5880 more reliable and durable during circuit board manufacturing.
4. Wide Range of Applications
- High-Frequency Communication: Due to its outstanding electrical properties, RT/duroid® 5880 is highly suitable for high-frequency and broadband applications, such as millimeter-wave communication, military radar systems, and commercial aviation telephone circuits. It supports a maximum frequency of up to the Ku band and beyond, making it the material of choice for designers in these fields.
- High-Humidity Environments: Its extremely low moisture absorption rate makes RT/duroid® 5880 particularly suitable for use in high-humidity environments, such as outdoor communication equipment or marine applications.
