Abstract
Various embodiments concern a method for manufacturing a disk drive head suspension component. Such methods can comprise providing a head suspension component comprising a layer of insulating material on a spring metal layer. Such methods can further comprise forming a strain gauge element and a trace seed layer by depositing a first metal on the insulating material layer, such as by sputtering. The strain gauge element and the trace seed layer can be formed simultaneously by the depositing of the first metal as part of the same process step. The first metal can be of a strain gauge class of metal having relatively high resistivity, such as constantan. Such methods can further comprise plating a second metal on the trace seed layer to form one or more traces.
