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.
