Patent ID: 8853562

Claim:
A printed wiring board device having an electromagnetically shielded portion, the printed wiring board device comprising a flexible electromagnetic, shielding film to electromagnetically shield a portion of the printed wiring hoard device, wherein the electromagnetic shielding film includes an insulating layer and a conductive metal layer which are laminated with a conductive adhesive layer provided therebetween to cover the portion, and the electromagnetic shielding film is disposed so that the insulating layer faces the printed wiring board device, the conductive metal layer having a higher melting temperature than that of the insulating layer; and wherein the conductive layer and a ground conductor of the printed circuit board device are adapted to be bonded and electrically connected via the conductive adhesive layer by heating the electromagnetic shielding film to a heating temperature to melt and contract the insulating layer, the heating temperature being higher than the melting temperature of the insulating resin layer and lower than the melting temperature of the conductive metal layer.
