Embodiment Construction

[0014] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are some of the embodiments of the present invention, but not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0015] Such as figure 2 As shown, a shielding film 200 includes: an insulating layer 1, a conductive layer 2 and a conductive adhesive layer 3, the insulating layer 1, the conductive layer 2 and the conductive adhesive layer 3 are stacked in sequence, and the The insulating layer 1 covers at least the side surface of the conductive layer 2 .

[0016] Wherein, the above-mentioned conductive layer 2 may be a silver layer, a copper layer or other conduc...

Abstract

The invention provides a shielding film, a flexible circuit board component and a mobile terminal. The shielding film comprises an insulating layer, a conductive layer and a conductive adhesion layer;the insulating layer, the conductive layer and the conductive adhesion layer are sequentially stacked; and the insulating layer at least wraps the side surface of the conductive layer. By adopting the shielding film provided by the invention, as the insulating layer at least wraps the side surface of the conductive layer, i.e. the side surface of the conductive layer is not exposed any more, thepossibility of short circuits of the shielding film and other devices can be reduced.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a shielding film, a flexible circuit board assembly and a mobile terminal. Background technique [0002] Electromagnetic Interference (EMI for short) refers to any electromagnetic phenomenon that may cause performance degradation or even failure of electronic devices (including electronic components, electronic devices, electronic equipment or electronic systems, etc.). Generally speaking, almost every electronic device will generate different degrees of electromagnetic interference signals, which will cause interference to other electronic devices around it. [0003] The current flexible printed circuit (Flexible Printed Circuit, FPC for short), usually adopts such as figure 1 The shielding film shown to solve the problem of electromagnetic interference. Such as figure 1 As shown, the shielding film includes an insulating layer 101 , a conductive layer 102 and a conduct...
