Process characteristics: high-frequency materials,Rogers RT/duroid 5880
RT/duroid 5880 is a high-frequency circuit board material launched by Rogers Corporation, which belongs to polytetrafluoroethylene fiberglass reinforced material. It has the following characteristics and advantages:
- Extremely low dielectric constant: Measured under the 10 GHz IPC-TM 2.5.5.5 standard, its dielectric constant is 2.20 ± 0.02, which can effectively reduce the dispersion and loss of signal transmission.
- Extremely low dielectric loss: Measured under the same standard, its dielectric loss factor is only 0.0009, which is suitable for high-frequency and wide-band applications.
- High-frequency support: The maximum supported frequency can reach the Ku band or even higher, which can meet the high-frequency requirements such as millimeter wave applications.
- Low moisture absorption rate: The moisture absorption rate is only 0.02%, making it have good stability and reliability in high humidity environments.
- Easy to process: It can be easily cut into the required shape to adapt to the requirements of various cavity structures.
- Chemical corrosion resistance: It can resist the erosion of all solutions and reagents used in the etching and plated through-hole processes.
- Good electrical performance: It has isotropy, and the electrical performance changes very little with the frequency.
Based on the above characteristics, the RT/duroid 5880 board is mainly used in the following fields:
- Commercial aviation telephone circuits
- Microstrip and stripline circuits
- Millimeter wave applications
- Military radar systems
- Missile guidance systems
- Point-to-point digital radio antennas.
