Claim:
1. A head suspension for supporting a head within a disk drive, the head suspension comprising: a load beam including a base portion for connection to an actuator for moving the load beam relative to a disk and a flexure for connection with a head and to permit movement of the head for orientation thereof relative to a surface of the disk; a microactuator operatively provided and coupled to the load beam for providing fine movements of the load beam relative to the disk, the microactuator including a surface for connection with an electrical source to effect fine movement of the load beam; a flexible circuit provided to extend along the load beam and comprising a plurality of electrical traces along an insulator layer, at least one trace including a connection pad positioned to extend over the surface connection of the microactuator for connection with a controllable power source for selective actuation of the microactuator, wherein the connection pad comprises a conductive first surface that is accessible by an opening within the insulator layer, an oppositely facing conductive second surface, and at least an edge portion between the first and second surfaces, and the connection pad is adhered to the surface connection of the microactuator solely and without further structural interconnection by a conductive adhesive that is adhered to the surface connection of the microactuator and to the first and second conductive surfaces and the edge portion of the connection pad so as to encapsulate the edge portion and at least adjacent edges of the first and second conductive surfaces with conductive adhesive for providing electrical conduction between the connection pad and the surface of the microactuator and also to solely physically connect the connection pad to the surface of the microactuator.
