Abstract

The invention provides a manufacturing method of an electromagnetic shielding sheet. The manufacturing method comprises the steps of providing at least one magnetic strip layer, forming a first glue layer on an upper surface of the magnetic strip layer and a second glue layer on a lower surface of the magnetic strip layer to form a magnetic lamination structure; smashing the magnetic lamination structure so that the magnetic strip layer is cracked to form a plurality of smashed pieces, wherein a smashed gap is formed between adjacent smashed pieces; and performing lamination on the smashed magnetic lamination structure so that at least one part of the smashed gap is partially filled with the first glue layer arranged on the upper surface and the second glue layer arranged on the lower surface. By the manufacturing method, the problem that the thickness of an existing electromagnetic shielding sheet is not applicable to small-size electronic equipment is solved.

Description

technical field

[0001] The invention relates to the field of electromagnetic shielding sheets, in particular to a method for manufacturing an electromagnetic shielding sheet. Background technique

[0002] Electromagnetic shielding (electromagnetic shield) refers to the use of conductive materials or ferromagnetic materials to shield the end of the stator core of the large-capacity turbogenerator to reduce the additional loss caused by the magnetic flux leakage at the end of the stator winding in the structural parts Measures with localized fever. In terms of communication, shielding is the electromagnetic isolation between two spatial regions to control the induction and radiation of electric fields, magnetic fields and electromagnetic waves from one region to another. Specifically, it is to surround the receiving circuit, equipment or system with a shield to prevent them from being affected by the external electromagnetic field.
