RT/duroid 5880(Rogers 5880) is a high-frequency laminate launched by Rogers Corporation. It is a micro-glass fiber reinforced PTFE (polytetrafluoroethylene) composite material. The randomly oriented microfibers reinforcement inside makes the PTFE composite material have exceptional Dk (dielectric constant) consistency.
Electrical properties:
Dielectric constant: Measured under the 10GHz IPC-TM 2.5.5.5 standard, the dielectric constant is 2.20±0.02. The extremely low dielectric constant helps reduce the propagation delay of the signal and improve the speed and efficiency of signal transmission.
Dielectric loss: Measured under the 10GHz IPC-TM 2.5.5.5 standard, the dielectric loss factor is 0.0009, which means that the energy loss during signal transmission is minimal, which helps maintain the integrity and strength of the signal.
Supported frequency: Supports the highest application signal frequency up to Ku band (12 to 18 GHz )or even higher.
Physical properties:
Moisture absorption rate: The moisture absorption rate is only 0.02%. The low moisture absorption rate helps prevent the material properties from changing due to moisture absorption, thereby maintaining the stability of the circuit board's performance, making it very suitable for use in high humidity environments.
Chemical resistance: It can resist the erosion of all solutions and reagents used in etching and through-hole plating, making it more reliable and durable in the circuit board manufacturing process.
Mechanical properties:
Glass fiber reinforcement: Glass fiber reinforcement, with random distribution of microfibers inside, provides additional strength enhancement for the production and processing of circuits, ensuring that the material can withstand certain mechanical pressure during manufacturing and application, and is not easy to break or deform.
Processability: It can be easily cut into the required shape and can adapt to the various requirements for the shape of printed circuit boards in high-frequency applications; it supports the thickness range of 8 to 70 microns for electro-deposited copper, providing greater flexibility for circuit board manufacturing.
Application: Due to its excellent electrical properties, low moisture absorption rate and other characteristics, it is widely used in many fields. Including commercial aviation telephone circuits, microstrip and stripline circuits, millimeter wave applications, military radar systems, missile guidance systems, point-to-point digital radio antennas, and scenes in high humidity environments such as outdoor communication equipment or marine applications.
