Abstract
An integrated lead suspension is formed from a laminate of three materials in a variety of configurations having from three to five layers. The materials are stainless steel, polyimide and copper. Each layer is essentially homogeneous, but may be formed with one or more holes or voids prior to the formation of the laminate. After the copper layer is etched to form a tab which overhangs the steel layer, the suspension is welded to a load beam. The load beam prevents the downward motion of the suspension. The tab acts as a flexure motion limiter for upward motion of the suspension. The voids allow a precise amount of polyimide undercut between the steel and copper layers which otherwise could not be achieved.
