| 20120073121 | METHOD FOR MANUFACTURING A DISK DRIVE HEAD SUSPENSION - A method for manufacturing a disk drive head suspension having a plated load point dimple. An aperture is etched into the spring metal member. A photoresist mask having an opening with load point-defining side walls and a load point diameter is formed over a portion of a spring metal member including the aperture. Metal is plated onto the spring metal member and into the aperture in the opening to form a load point having the load point diameter on the spring metal member. | 03-29-2012 |
| 20110162203 | MULTI-LAYER GROUND PLANE STRUCTURES FOR INTEGRATED LEAD SUSPENSIONS - Multi-layer ground plane structures and methods of manufacture for integrated lead suspension flexures. A flexure in accordance with one embodiment of the invention includes an insulating layer, a plurality of traces on the insulating layer and a stainless steel base layer on the side of the insulating layer opposite the traces. The stainless steel base layer includes one or more void portions with voids in the base layer opposite the insulating layer from the traces and one or more backed portions with the base layer backing the traces. A plurality of patterned and transversely-spaced first conductive ground planes are located opposite the insulating layer from the traces at the void portions and backed portions of the stainless steel base layer. A continuous gold second conductive ground plane is located opposite the insulating layer and the first ground planes from the side of the insulating layer adjacent to the traces at the void portions and backed portions of the stainless steel base layer. The gold ground plane can be used as an etch stop during formation of the voids in the base layer. | 07-07-2011 |

| 20090287071 | PATIENT INTERFACE FOR SPECTROSCOPY APPLICATIONS - A patient interface and method of locating the patient interface for use particularly in spectroscopy applications. The patient interface includes a concave region and first and second convex regions. A wing extends from the concave region to help locate the patient interface properly. The convex regions provide additional adhesion support, particularly when used on the thenar eminence. The patient interface may be placed in a number of locations on a patient to determine an optimum location for measurement prior to affixing the interface to the patient. | 11-19-2009 |
| 20090009910 | METHOD OF ALIGNING COMPONENTS FOR INSTALLATION ON A HEAD SUSPENSION ASSEMBLY - A head suspension for supporting a head slider over a storage media in a dynamic storage device is provided with a head suspension component having a spring metal layer, an electrically conductive layer and a dielectric layer interposed between the metal layer and the electrically conductive layer. A plurality of electrically conductive traces with bond pads are formed in the electrically conductive layer. A feature datum is also formed in the electrically conductive layer on a detachable carrier strip. The feature datum defines a first edge in the electrically conductive layer parallel to an edge of the bond pads. | 01-08-2009 |
| 20080273269 | DISK DRIVE HEAD SUSPENSION FLEXURES HAVING ALTERNATING WIDTH STACKED LEADS - An integrated lead flexure for a disk drive head suspension of the type having a plurality of stacked leads disposed on separate layers, the plurality of stacked leads extending between terminal connector pads and head connector pads, comprising stacked lead pairs having opposing and regularly alternating wider and narrower portions, respectively. | 11-06-2008 |
