Japan 5G: Sumitomo Electric Industries mass-produces fluororesin FPC: Low dielectric constant and dielectric loss tangent
Sumitomo Electric Industries:
September 2020,
In the millimeter wave band
Low transmission loss
It was also excellent in flexibility.
Fluororesin flexible printed circuit board (FPC)
Announced that it has succeeded in developing and mass-producing “FLUORO CUIT”.
FLUOROCUIT:
We will propose the use of 5G systems in the millimeter wave band.
Comparison of transmission loss: Fluororesin and liquid crystal polymer
Fluororesin has extremely low dielectric constant and dielectric loss tangent.
Compared to liquid crystal polymer (LCP), which is increasingly used for high frequency substrates
The transmission loss can be further reduced.
The transmission loss in the 40 GHz band is about 40%.
Moreover, the higher the frequency, the more the characteristics can be utilized.
However, it has been said that processing has been difficult and productivity has been a problem.
Field of use:
This time, we have made it possible to mass-produce fluororesin FPC, which was considered difficult to process.
It also has excellent flexibility and is suitable for wiring that requires curved surface mounting.
New product,
Wiring in the data center,
5G base station.
Antennas and wiring materials for terminal equipment,
radar,
To sensors etc.
