Composite absorbing material shields flexible FPC electromagnetic radiation

Author:admin   AddTime:2021-03-29

Problem: There is strong electromagnetic radiation when connecting the LCD module and the FPC flexible board of the mobile phone motherboard.

Solution: The absorbing material with a magnetic permeability of 50 (3 MHz) can be attached to the flexible board of the display module. It also has absorption and shielding functions, which effectively absorbs electromagnetic radiation, and can also strengthen the flexible FPC to prevent breaking.



The composite absorbing material is compounded with a layer of metal copper foil or aluminum foil tape on the surface of the soft absorbing film. It is a shielding absorbing material with high magnetic permeability. It has broadband absorbing performance and excellent shielding efficiency. Pressure-sensitive adhesive does not contain the characteristics of RoHS directive harmful substances. It is mainly used in touch display FPC and places that need to shield interference sources and magnetic isolation, and solve the noise between the data line and the base by winding the cable, so as to reduce the effect of electromagnetic interference.
