Abstract: An apparatus includes a printed circuit board and a flexible printed circuit. A rigid structure component is on a first side of the printed circuit board. An interconnection interface is on a second side of the printed circuit board opposite to the rigid structure component and is configured to interconnect the flexible printed circuit and the printed circuit board. A conductive interconnection material is at the interconnection interface between the flexible printed circuit and the printed circuit board.

Abstract: An assembly comprises a flexible circuit board (FCB) having a substrate with a top side, and a circuit pattern layer on the top side of the substrate. The circuit pattern layer has a connection region for facilitating electrical interconnection to the FCB, and one or more cavities extending through both the substrate and the circuit pattern layer. A first conductive layer for electro-magnetic interference (EMI) shielding is positioned on a top side of the FCB, and a second conductive layer for EMI shielding is positioned on a back side of the FCB. Electrically conductive adhesive extends through the one or more cavities for electrically connecting the first conductive layer and the second conductive layer. The electrically conductive adhesive further extends from the first conductive layer to the connection region for facilitating electrical interconnection of the first conductive layer and the second conductive layer.
