SF series electromagnetic shielding film is a hot-pressed shielding film based on high molecular liquid crystal polymer, effectively inhibiting the electromagnetic interference between the components on the circuit board, reducing the attenuation of the transmission signal in the FPC and the incompleteness of the transmission signal, which provides a good solution for the electromagnetic shielding of the flexible circuit board FPC. And It has become an important raw material for the high-frequency and high-speed FPC, which can meet the integrity requirements of high-frequency signal transmission and effectively shield the interference of electromagnetic waves.

1)With high molecular liquid crystal polymer as the base material, it has the characteristics of low Dk, low Df and low dielectric loss, and adopts the unique fiber metallization process, which can achieve higher shielding performance.

2) It has good connectivity with small ground diameter (ground diameter φ0.5) and good followability of high level difference (60μm).

3) By adopting uniquely designed shielding layer and bonding layer, ultra-thin design is realized, and low connection resistance is ensured.

4) It has good soldering resistance, chemical resistance and abrasion resistance, and contributes to the freedom of circuit design.

Product advantages:

The product has the characteristics of excellent flexibility, extremely low insertion loss, extremely high shielding effectiveness, extremely low small ground diameter impedance and high segment difference.

Product application:

It is specially applied to flexible circuit boards and rigid-flex boards and widely used in LCD modules and camera modules of smart phones, tablet computers and other electronic products.
