Abstract
An integrated lead flexure includes traces with windowed or reduced width portions. The flexure includes a metal base layer with a plurality of apertures, an insulating layer on the metal base layer, and one or more conductive traces formed on the insulating layer and extending over the metal base layer and the plurality of apertures. Backed portions of the one or more conductive traces that extend over the metal base layer have a first width, and unbacked portions of the one or more conductive traces that extend over the plurality of apertures have a second width that is less than the first width.
