Abstract
A film shielding against electromagnetic interference comprises an insulating layer, a silver layer, and a conductive adhesive layer. The insulating layer is made of polyimide. The metal layer is formed on the insulating layer. The conductive adhesive layer is coated on the metal layer and is very thin but renders the film less prone to bubbling and rupturing when in place.
Claims10
An electromagnetic shielding film comprising:
- a polyamide insulating layer;
- a silver layer, formed on the insulating layer;
- a conductive adhesive layer, wherein the conductive adhesive layer is coated on the silver layer.
A method of manufacturing an electromagnetic shielding film, comprising:
- providing a first insulating layer, wherein the insulating layer is metallized to obtain a silver layer;
- painting a conductive adhesive on a surface of the metal layer to form a conductive adhesive layer.
