Patent ID: 8836830

Claim:
A flexible printed circuit board assembly, comprising: a flexible printed circuit board comprising: a first surface; and a conductive layer positioned on the first surface, the conductive layer comprising a circuit portion and a grounding portion connected to the circuit portion; a dielectric layer, the circuit portion entirely covered by the dielectric layer and the grounding portion exposed outside the dielectric layer; a stiffener comprising a contact surface; and a layer of conductive adhesive positioned on the contact surface, the conductive adhesive comprising a first adhering portion and a second adhering portion; wherein a thickness of the second adhering portion is greater than the first adhering portion, a thickness difference between the second adhering portion and the first adhering portion is substantially equal to a thickness of the dielectric layer, the first adhering portion is adhered to the dielectric layer, and the second adhering portion is adhered to the grounding portion.
