Abstract
A hard disk drive suspension assembly includes a pad base layer, a pad-end fixing layer, and a plurality of electrical pads each comprising a conductive layer on the pad base layer, where the base layer extends to the fixing layer, to which a distal end of the base layer is fixed. This configuration inhibits the delamination or deformation of the end edge of each pad. An additional cover layer may be implemented to cover the distal end of the conductive layer(s), further inhibiting deformation of the pads. These techniques are especially relevant with narrow, high-density, small pitch electrical pads.
