摘要： A disk drive suspension circuit has copper signal conductors connected by vias through an insulative layer to respective stainless steel flying leads. The stainless steel flying leads are activated and plated with one or more metals, with a final layer over the flying lead being a layer such as gold, suitable for bonding to form bond pads. The gold bond pads may be attached using thermosonic welding, solder ball bonding, or other suitable methods to an electrical component such as wires or a the disk drive's pre-amp circuit.

摘要： An additive process disk drive suspension interconnect, and method therefor is provided. The interconnect has a metal grounding layer of typically stainless steel or copper metallized stainless steel, a metal conductive layer and an insulative layer between the metal grounding layer and the conductive metal layer. A circuit component such as a slider is electrically connected to the conductive layer along a grounding path from the circuit component and the conductive layer to the metal grounding layer through an aperture in the insulative layer. For improved electrical connection a tie layer is provided through the insulative layer onto the grounding layer in bonding relation with the ground layer. A conductor is deposited onto both the conductive metal layer and the tie layer in conductive metal layer and tie layer bonding relation, and the circuit component is thus bonded to the grounding layer by the conductor.

摘要： A structure for a load beam used in hard disk drive devices includes an asymmetric structure. The load beam exhibits longitudinal asymmetry (i.e., is asymmetric along its long axis) in regard to the weight distribution, but has a center of mass that lies along its longitudinal axis due to the provisioning of counterbalancing features, such as the addition of material, the removal of material, or a combination of adding material and removing material, or the use of an asymmetrical damping layer.
