Abstract:
A head gimbal assembly for a disk drive includes a laminate flexure having a structural layer, first and second conductive layers, a first dielectric layer between the first and second conductive layers, and a second dielectric layer between the structural layer and the second conductive layer. The second conductive layer includes a plurality of electrical traces. Each of a plurality of flexure bond pads includes a widened region of a corresponding one of the plurality of electrical traces in the second conductive layer, a corresponding one of a plurality of segments or discontinuous islands in the structural layer, and a corresponding one of a plurality of discontinuous islands in the first conductive layer that is electrically connected to an electrical trace in the second conductive layer through one of a plurality of conductive vias through the first dielectric layer.
