A method for manufacturing a disk drive head suspension including a load beam, a flexure and a limiter for restricting the range of motion of the flexure with respect to the load beam. The load beam includes an aperture and an engaged portion adjacent to the aperture. The flexure, in an unformed state, includes a slider mounting region and a generally planar engagement structure extending from the slider mounting region. The engagement structure includes a tab portion extending from the slider mounting region and a hook portion extending from the tab portion. During a first forming operation the hook portion is bent around a tooling die to a ninety degree angle with respect to the tab portion. The flexure is then welded to the load beam with the hook portion extending into the aperture. During a second forming operation the tab portion is bent around a tooling die to a ninety degree angle with respect to the slider mounting region. The second forming operation causes the hook to extend over the engaged portion of the load beam. The first and second forming operations can be performed with tooling moving only in a z-direction.

Method of manufacturing for a disk drive head suspension for a fold over limiter

A head suspension for supporting a head slider over a rigid disk in a dynamic storage device having a component that includes a compliant feature adapted to engage a first pin and a datum engaging surface spaced from the compliant feature. The component being locatable relative to a datum by manipulation of the component with respect to the datum and a first pin to cause the first pin to engage and deflect the compliant feature when the datum engaging surface of the component is engaged and positioned with respect to the datum. The head suspension also including a second component having a pin engaging feature and possibly a datum engaging surface alignable with the compliant feature and datum engaging surface of the first component, respectively. The pin engaging feature of the second component being compliant or non-compliant. The compliant and non-compliant features being usable for locating head suspension components, such as load beams, flexures, and base plates, relative to each other or to tooling for head suspension fabrication purposes. The compliant and non-compliant features also being usable for locating other types of small precision components relative to a datum or to each other. A method for locating a component relative to a datum using a compliant feature formed within the component is also provided.
