Abstract
A circuit board assembly includes a flexible circuit board and a reinforcing plate. The flexible circuit board includes a surface. A conductive layer is positioned on the surface. The conductive layer includes a circuit portion entirely covered by a dielectric layer and a grounding portion exposed outside the dielectric layer. The reinforcing plate is mounted on the dielectric layer. The reinforcing plate includes a connection surface connected to the dielectric layer and a supporting surface facing away from the connection surface. Projections extend from the connection surface. The location of all of the projections correspond to the location of the grounding portion, and all of the projections are in electrical contact with the grounding portion by means of a conductive adhesive.
