Suitable for point-to-point digital radio antennas, microstrip and stripline circuits, millimeter wave applications, missile guidance systems, military radar systems, high-frequency circuit boards for commercial aviation telephones, etc.

Processing Technology:

The processing technology is similar to FR-4, but the cost is lower, providing high cost performance and excellent dimensional stability.

Environmental Protection Standards:

Meet the lead-free process standards and are suitable for applications with strict environmental protection requirements.

Minimized Design Specifications:

Minimum drilling 0.3mm, minimum line width 0.35mm, minimum line spacing 0.2mm, these specifications help to achieve high-density circuit design.

High Frequency Support:

Can support applications up to Ku band or even higher frequencies, suitable for the needs of modern high-frequency communication technology.

Good Electrical Performance:

Maintain consistent electrical characteristics over a wide frequency range to ensure the stability and reliability of signal transmission.

Dimensional Stability:

Due to the isotropy of the material, its electrical properties change very little with frequency, ensuring the performance consistency of the circuit board at different frequencies.

Heat Resistance:

Rogers 5880 material has good heat resistance and is suitable for use in higher temperature environments.

Chemical Resistance:

The material is able to resist chemical agents used in the production process, such as etchants and plating solutions.

Mechanical Strength:

Due to the reinforcement of glass fiber, the material has high mechanical strength and is suitable for use in applications that need to withstand certain mechanical stress.

Easy Processing:

The material is easy to cut, drill and other processing operations, which facilitates the realization of complex circuit board designs.

Environmental Stability:

The material is less sensitive to environmental changes (such as temperature and humidity), ensuring reliability under different environmental conditions.

Electromagnetic Compatibility:

Due to low dielectric constant and low dielectric loss, it helps to improve the electromagnetic compatibility of the circuit.

Long-term Reliability:

The long-term stability and durability of the material ensure the reliability of the circuit board in long-term use.
