Are the shielding film and covering film of FPC the same thing?
Hello, this is Mr. Zhou from Shenzhen Chixin Electronics. The company specializes in FPC production, so I have a better understanding of this aspect. The shielding film is an electromagnetic film, black, which is mainly used to shield external signal interference. Coating is a film that covers and presses on the surface of the substrate, usually polyimide resin, that is, PI, which is used to resist welding and has little effect on signal shielding. Electromagnetic film is usually attached to the covering film, and the price of electromagnetic film is much more expensive than that of covering film. Hope to adopt
