What is Rogers PCB board? What's the difference?

1. What is Rogers PCB?
Rogers PCB board is a high-frequency PCB material model produced by Rogers Company, which has the following characteristics:

① Material advantages: Rogers PCB uses ceramic or special polymer composite materials and does not contain epoxy resin, so it has lower dielectric constant (DK) and dielectric loss, as well as excellent temperature stability. These characteristics make Rogers PCB perform especially well in high-frequency environments.

② High precision and stability: The board thickness control has high precision, the copper sheet has strong adhesion, good heat dissipation performance, and no delamination or blistering, ensuring the long-term stability and reliability of the PCB.

③ Wide range of applications: Suitable for areas with high reliability requirements such as high-speed PCB design, commercial microwave antennas, radio frequency products, and aerospace.

2. What is the difference between Rogers PCB board and traditional PCB (such as FR-4)?
①Material composition 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.

②Performance difference: Dielectric constant (DK): The DK value of Rogers PCB is lower and stable with frequency, which helps to reduce reflection and loss in signal transmission; the DK value of FR-4 is higher and changes greatly with frequency. . Temperature stability: Rogers PCB has excellent temperature stability and is suitable for working in a wide temperature range; FR-4 performance may decrease in high temperature environments. Water absorption: Rogers PCB has extremely low water absorption and is suitable for high humidity environments; FR-4 is relatively easy to absorb water, which may affect electrical performance.

③Cost and application: Although Rogers PCB has high material cost, due to its excellent performance, it is especially suitable for fields with extremely high performance requirements; while FR-4 is widely used in the manufacturing of general electronic products because of its lower cost. .

④ Processing compatibility: Although the materials are different, the processing technology of Rogers PCB is compatible with FR-4 to a certain extent, which provides manufacturers with more choices.
