Abstract:
1. A flex-print circuit (FPC) attached to at least one bonding pad on a suspension of a head gimbal assembly in a hard disk drive using anisotropic conductive adhesive, comprising: a base film; a conductive layer situated below the base film; an overcoat layer comprising at least two sections situated below the conductive layer, a bottom surface of each section overlapping partially and to be pressed onto a top surface of the bonding pad; and a conductive structure forming an electric conduit between the conductive layer and the at least one bonding pad, said anisotropic conductive adhesive being disposed at least partially surrounding the conductive structure for bonding the FPC to the at least one bonding pad, wherein the conductive structure comprises a filling completely occupying a space formed by the at least one bonding pad, the conductive layer, and the at least two sections of the overcoat layer.
