Certain exemplary aspects of the present disclosure are directed towards apparatuses and methods which autonomously decontaminate parts. Parts to be cleaned are identified, and based on the identification of the part, a part specific cleaning program is initiated. During the cleaning, the part is manipulated about a gas supply in such a way that the drag force on the contamination particles attached to the part exceeds the contamination particles' surface adhesion force and accordingly is removed from the surface of the part. The removed contamination is then evacuated from the atmospheric environment near the part by a low pressure zone of a second gaseous material near the part.

Workpiece cleaning

An apparatus and associated method are provided for treating a workpiece with a cryogenic impingement fluid. A fixture supports the workpiece in an upright position and operably connects an electrical component of the workpiece to a power source in the supported position. A cryogenic impingement fluid applicator sprays a stream of the cryogenic impingement fluid against the supported workpiece and laterally moves the stream in accordance with a predetermined path. A shield deflects the stream of cryogenic impingement fluid to prevent the stream from contacting at least a part of the workpiece as the stream is moved along the predetermined path.

A disc drive includes a case defining a maximum interior height for mounting a voice coil motor within the disc drive. The voice coil motor includes a magnet, a coil, and top and bottom plates for carrying magnetic flux in a circuit with the magnet. At least one of the top and bottom plates includes a raised central portion having an increased cross-sectional area in relation to the remainder of the plate for carrying additional magnetic flux at a point where the plate experiences peak levels of magnetic flux. An opening formed in the disc drive case accommodates the raised central portion of the plate without altering the overall height of the case. The height of the raised central portion is preferably substantially equal to a thickness of the case to ensure the raised central portion fits flush within the opening. One or both of the top and bottom plates may include the raised central portion, thereby necessitating openings in one or both of a top cover and a lower base portion of the disc drive.
