To process RT/duroid 5880 PTFE glass fiber sheet, the following requirements should be paid attention to in order to ensure the dimensional stability.
1. In order to increase the bonding force of the inner medium surface, it is necessary to protect the roughness of the medium surface after etching;
2. For the surface of the medium is pure PTFE material, it is recommended to do sodium naphthalene or plasma treatment;
3. Before pressing, make sure that the surface of the board is clean/dry and cannot be brushed mechanically;
4. According to the type of bonding sheet, choose the inner copper surface treatment, oxidation or oxidation substitution method. It is recommended that the PCB processing factory strictly follow the Teflon PCB, PTFE multilayer board processing guide to set the process flow.
Rogers RT/Duroid 5880 high frequency PCB is made of PTFE glass fiber reinforced material. High frequency circuit design always has strict requirements for the dielectric constant of printed circuit board. The dielectric constant of RT5880 measured at 10 GHz working frequency is only 2.2, which is obviously lower than that of similar materials on the market at present. Therefore, from the perspective of performance parameters and production cost, the board is more suitable for high-frequency design and application than similar products. At the same time, the dielectric loss of the plate measured under the same standard is only 0.0009. The extremely low dielectric loss makes it very suitable for high frequency and wide band design applications requiring minimum dispersion and loss, It is mainly used in high frequency circuit board of point-to-point digital radio antenna, microstrip and stripline circuit, millimeter wave application, missile guidance system, military radar system and commercial aviation telephone.
The characteristics of Rogers 5880 PCB are as follows
1. Very low dielectric constant, measured at 10 GHz, the dielectric constant is 2.20 ± 0.02
2. Very low dielectric loss, measured at 10 GHz, the dielectric loss factor is 0.0009
Rogers 5880 PCB Material
Rogers RT/duroid 5880 (Rogers 5880) material
Rogers RT/duroid 5880 high frequency laminates are PTFE composites reinforced with glass microfibers.
RT/duroid 5880 laminates has a low dielectric constant (Dk) and low dielectric loss, making them well suited for high frequency/broadband applications. Helping to maintain the Dk uniformity are the randomly oriented microfibers reinforcing the PTFE composites.
