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. The voids can be used to eliminate the need for double-sided etching or to make small features which would otherwise be unavailable with conventional manufacturing processes.
