In the field of electronic engineering, there will be a variety of PCB boards, one of which is Rogers PCB, relying on superior performance and material characteristics, widely used in high-speed signal transmission, microwave antennas and RF products and other high-end electronics, this article will briefly outline Rogers PCB board, hope to help your friends.
1. What is Rogers PCB board?
Rogers PCB board is a high frequency PCB data model produced by Rogers Company, with the following characteristics:
Material advantages: Rogers PCBS are made of ceramic or special polymer composites and do not contain epoxy resins, so they have lower dielectric constant (DK) and dielectric loss, as well as excellent temperature stability. These characteristics make Rogers PCBS perform particularly well in high frequency environments.
High precision and stability: high precision plate thickness control, strong adhesion of copper sheet, good heat dissipation performance, no stratification, foaming phenomenon, to ensure the long-term stability and reliability of PCB.
Wide application: suitable for high-speed PCB design, commercial microwave antennas, RF products and aerospace and other areas with high reliability requirements.
2, Rogers PCB board and traditional PCB (such as FR-4) What is the difference?
Rogers PCB uses ceramic or special polymer materials, while FR-4 is mainly composed of epoxy resin and glass fiber. Rogers materials have superior dielectric properties and are suitable for high frequency applications.
② Performance difference:
Dielectric constant (DK) : Rogers PCB's DK value is lower and stable with frequency, helping to reduce reflection and loss in signal transmission; The DK value of FR-4 was higher and varied with frequency.
Temperature stability: Rogers PCB has excellent temperature stability, suitable for working in a wide temperature range; FR-4 performance may deteriorate at high temperatures.
Water absorption: Rogers PCB water absorption is very low, suitable for high humidity environment; FR-4 absorbs water relatively easily and may affect electrical performance.
(3) Cost and application: Although Rogers PCB material cost is high, but because of its excellent performance, it is especially suitable for areas with high performance requirements; FR-4 is widely used in the manufacture of general electronic products because of its low cost.
Processing compatibility: Although the material is different, the processing technology of Rogers PCB is compatible with FR-4 to a certain extent, which provides manufacturers with more room for choice.
