Abstract
A head suspension for a head/gimbal assembly comprises a flexure attached to a load beam. The load beam includes a lifter tab configured to engage a lifting surface of a load/unload ramp. The flexure includes a limiter tab, extending from a trailing edge thereof, that is configured to engage with a gimbal-limiting surface of the load/unload ramp. The limiter tab comprises a metallic base layer, a metallic stiffening layer, and a non-metallic intermediate layer disposed between the base and stiffening layers. The stiffening layer can include both conductive traces that terminate with a set of bonding pads and an appendage that extends along a length of the limiter tab. The appendage portion of the stiffening layer serves to increase the thickness of the limiter tab to increase the stiffness of the limiter tab.
