Abstract

The invention provides a flexible circuit board with an electromagnetic interference shielding structure. The flexible circuit board comprises a flexible circuit board body and the electromagneticinterference shielding structure. The electromagnetic interference shielding structure comprises a bonding layer, an insulating layer and a metal shielding layer. Two opposite sides of the insulatinglayerare in direct contact with the bonding layer and the metal shielding layer. The electromagnetic interference shielding structure is configured on the flexible circuit board body. The bonding layer ofthe electromagnetic interference shielding structure is in direct contact with the flexible circuit board body. An electromagnetic interference shielding structure is also provided. The flexible circuit board with the electromagnetic interference shielding structure is also provided.

Description

technical field [0001] The invention relates to an electromagnetic interference shielding structure, an electronic component and a manufacturing method thereof, in particular to an electromagnetic interference shielding structure applied to a flexible printed circuit board, a flexible circuit board with an electromagnetic interference shielding structure and a manufacturing method thereof. Background technique [0002] With the development of high-frequency signal transmission, multi-layer printed circuit boards (multi-layered PCB, which can be referred to as: multi-layer boards) are used in many electronic products, and the inner layer (that is, not located at the top or bottom layer) ) lines are used for high-frequency signal transmission. [0003] Multilayer printed circuit boards often have bonding sheets. Adhesive sheets are mostly made of glass fiber or other fibers impregnated with resin through partial polymerization. Therefore, the thickness of the electronic prod...
