Abstract
The invention relates to a flexible electromagnetic shielding sheet and an electronic device provided with the same, the flexible electromagnetic shielding sheet comprising: a pressure-sensitive adhesive tape provided with an electroconductive adhesive layer on one side; a fiber web, formed by accumulation of fiber, adhered to the electroconductive adhesive layer; a metal layer, on at least one surface of the fiber web, for shielding against electromagnetic waves; and an insulation film adhered to the fiber web provided with the metal layer. Furthermore, the pressure-sensitive adhesive tape comprises: accumulated-fiber-type material formed by accumulation of a plurality of fibers, and provided with a plurality of pores; and an electroconductive adhesive layer, on both surfaces of the accumulated-fiber-type material and made of electroconductive adhesive material filling the plurality of pores, for electrically connecting due to applied pressure.
Description
technical field [0001] The present invention relates to an electromagnetic wave shielding sheet, and in more detail, relates to a flexible electromagnetic wave shielding sheet which is excellent in flexibility and can improve electromagnetic wave shielding efficiency, and an electronic device having the same. Background technique [0002] In recent years, as electronic devices including mobile phones, tablet PCs, notebook PCs, and digital cameras have become more high-performance and more functional, various components are also being deployed. [0003] In addition, the development of flexible components is being actively implemented as the demand for highly lightweight and flexible electronic devices increases. [0004] When components built into such electronic equipment perform with high performance and multifunction, heat and electromagnetic waves are generated, and in the case of electromagnetic waves flowing into components or flowing out to the outside, electromagnetic...
