Inverted Dimple Suspension Design

The figure illustrates a suspension design for the location of a load dimple with respect to a slider in a hard file head/suspension assembly. The design provides for the attainment of tight tolerances.

Normally the suspension load dimple is placed in the suspension flexure, and that flexure is then welded to the load beam portion of the suspension. Since either the load beam or a mount plate attached to the opposite end of the load beam from the flexure is used to locate the suspension during slider bonding, the locational tolerance of the flexure to load beam weld is included in the misalignment between the load dimple and the slider air bearing surface (ABS).

However, the figure shows, in this design, that a load dimple 4 is moved from a flexure 1 to a load beam 3. As an additional aid to achieving tight tolerances, V-notched tooling holes 2 are used in load beam 3.
