摘要:
An integrated pivot-carriage for a hard-disk drive. The integrated pivot-carriage includes a carriage having a center-bore with an integrated bearing-spacer portion. The integrated pivot-carriage also includes a pivot-shaft configured to provide support for rotation of the carriage. The pivot-shaft is disposed within the center-bore of the carriage. In addition, the integrated pivot-carriage includes at least one raceless ball-bearing that is configured to allow rotation of the carriage about the pivot-shaft. The raceless ball-bearing is disposed between the pivot-shaft and the carriage.

A disk drive spoiler for reducing particle accumulation in a hard disk drive is provided. The spoiler includes a body portion for directing airflow generated by a rotating disk, the rotating disk comprising a middle diameter and an outer diameter wherein the body portion directs airflow away from the outer diameter of the disk. The spoiler also includes an end portion for directing airflow away from the middle diameter of the disk towards the outer diameter of the disk wherein the body portion comprises a substantially similar width between the middle diameter and the outer diameter.

A method for analyzing particulate contaminant on a part comprises: applying a pressurized liquid onto the part on which the particulate contaminant is to be analyzed, wherein applying the pressurized liquid provides a dispersed spray of pressurized liquid; collecting an applied volume of the pressurized liquid; providing the applied volume onto a filter apparatus; and providing the filter apparatus for performing analysis of the particulate contaminant.
摘要:
A system and method for detecting a defect in an actuator arm conductor coil is disclosed. An actuator arm including a conductor coil is received. The conductor coil is coupled with a voltage as an anode. The conductor coil is submerged into a first solution, the first solution having no organic matter therein. The first solution is then coupled with a second solution including an organic indicator. The second solution also includes a cathode coupled to the voltage such that a defect in an insulation layer of the conductor coil is indicated by the organic indicator.

Embodiments of the present invention pertain to automatically removing contaminants from a manufactured part. According to one embodiment, a first robotic arm automatically holds the manufactured part. A second arm automatically sprays the manufactured part with a solution that causes contaminants to be removed from the manufactured part. The solution is collected. The collected solution contains the contaminants that were removed from the manufactured part.
摘要:
Removing contaminants from an electroless nickel (EN) plated surface. A surface of an EN plated object is washed in a first deionized water to remove a first portion of surface contaminants. The surface is immersed into a chemical solution wash for a pre-determined duration to remove nickel phosphate particles from the surface, wherein the chemical solution wash comprises at least one type of chelating agent dissolved in a solvent. The chemically washed surface is then washed in a second deionized water to remove a second portion of the surface contaminants.
