Title: ELECTROMAGNETIC WAVE SHIELDING STRUCTURE AND MANUFACTURING METHOD THEREFOR
Abstract:
An electromagnetic wave shielding structure and a manufacturing method therefor are disclosed. The disclosed electromagnetic wave shielding structure comprises: a shielding dam for encompassing at least one circuit element on a printed circuit board; an insulating layer for covering the at least one circuit element; and a shielding layer for covering the shielding dam and the insulating layer, wherein: the insulating layer includes a first layer having a first thickness in a downward direction from the surface thereof during a pre-hardening treatment, and a second layer formed under the first surface to have a thickness greater than the first thickness; and a boundary is formed between the first and second layers by a complete hardening treatment carried out after the pre-hardening treatment.
