ABSTRACT:
The present invention provides a new tab structure for a head suspension assembly in a magnetic storage system. In the prior art method of assembly, a harness temporarily holds a wire assembly. The present invention eliminates the need for the harness, thereby reducing the number of parts and steps as well as improving productivity and quality. A flexure of a suspension assembly must be manufactured very precisely. The present invention provides a new tab structure either integral with or separate from the flexure. Wires bridge over to an extension on the tab structure at a predetermined distance from the end of the load beam. Positioning holes, using the extreme flatness of the tab structure, align the wires with the bonding pads of a head. The suspension assembly is subsequently bonded to the head, and the unwanted tab structure is removed to complete the head suspension assembly.
