Considerations for Processing Rogers RTduroid 5880 PTFE Glass Fiber Boards !

Author: Jack Wang

When processing Rogers RT/duroid 5880, a high-frequency PCB material, there are several key points to keep in mind, especially to ensure dimensional stability:

1.Surface Treatment:

After etching, make sure to protect the roughness of the dielectric surface, as this enhances the bonding strength of the inner layer. If the dielectric surface is pure PTFE material, sodium treatment or plasma treatment is recommended to improve adhesion.

2.Cleaning and Drying:

Before milling, ensure the board surface is clean and dry. Avoid using mechanical brushes, as they may damage the surface.

3.Copper Surface Treatment:

Depending on the type of bonding sheet used, choose the appropriate treatment method for the inner copper layer, such as oxidation or alternative methods. It is recommended that PCB manufacturers strictly follow the processing guidelines for Teflon PCBs and PTFE multilayer boards when setting up the process flow.

Features of Rogers RT/Duroid 5880 High-Frequency PCB

Rogers 5880 is a high-frequency PCB made from PTFE glass fiber-reinforced material, making it particularly suitable for high-frequency circuit design. Its dielectric constant is only 2.2 at 10GHz, lower than most similar materials on the market, and its dielectric loss is as low as 0.0009. This means it performs exceptionally well in high-frequency and broadband designs, especially in applications requiring minimal dispersion and loss.

Key Application Areas:

Point-to-point digital radio antennas

Microstrip and stripline circuits

Millimeter-wave applications

Missile guidance systems

Military radar systems

Commercial aviation telephones

Core Advantages of Rogers 5880

1.Ultra-Low Dielectric Constant:

At 10GHz, the dielectric constant is only 2.20±0.02, making it ideal for high-frequency designs.

2.Ultra-Low Dielectric Loss:

At 10GHz, the dielectric loss factor is 0.0009, which is almost negligible.

3.Excellent Processability:

This material is easy to cut, drill, and shape, and it is resistant to etching and plating, making it suitable for use in high-humidity environments.

4.Uniform Electrical Performance Across Broad Frequencies:

Its electrical performance remains stable across a wide frequency range, making it suitable for various high-frequency applications.

Why Choose Rogers 5880?

Rogers 5880 not only offers superior performance but is also highly processable. Its low dielectric constant and low loss characteristics make it stand out in high-frequency designs. Whether for military radar or commercial aviation telephones, it delivers consistent performance.
