摘要:
A method of manufacturing and an overmolded mounting base. A plate is provided with mounting surfaces having a range of alignments including a nominal alignment. The plate is overmolded to form an overmolded plate. The overmolding changes the alignment of the mounting surfaces. The overmolded plate is maintained at a creep temperature for a time interval sufficient for creep to restore the alignment toward the nominal alignment.

A base assembly for use in an airtight enclosure. The base assembly includes a metal stamped section and an overmold section formed adjacent to the metal stamped section. The overmold section includes at least one stress relief feature for eliminating distortion stresses exerted on the metal stamped section by the overmold section.

The invention includes techniques for mounting a printed circuit board (PCB) on a housing for an electronic device. The housing includes a top cover that combines with a base to form an internal space within the housing. The PCB has at least one tab that extends from it and fits within a recess formed by the base to secure the PCB on a side of the base opposite to the internal space. The electronic device may additionally include a shield such that the PCB fits between the shield and the base and the shield assists in securing the PCB to the base. The housing may also include a locking mechanism to constrain the PCB tab to the base. Embodiments of the invention allow for a PCB to be mounted to an electronic device housing without the use of screws.

Method and apparatus for protecting a data storage device from fluid-borne contaminants. The device includes a housing in which a rotatable disc is disposed. The housing is formed from first and second rigid housing members. The first housing member is provided with an exterior filter support surface, an opposing interior surface and at least one filter access aperture. A contaminant adsorbent filter is placed on the exterior filter support surface, and a seal is applied to the first housing member to encapsulate the filter. During subsequent rotation of the disc, fluidic currents pass across the interior surface, through the at least one filter access aperture and to the adsorbent filter. Preferably, the filter is installed after the first and second housing members are mated. The filter support surface is preferably formed as part of a recess in the first housing member which projects into the housing.

A base of a data storage system includes a motor assembly. The motor assembly s includes a rotor that extends through an aperture in the base. The aperture extends from an inner surface to an outer surface of the base. The motor assembly also includes a motor stator mounted on the outer surface of the base. The motor stator includes a plurality of stator teeth radially and symmetrically arranged about the aperture in the base which are configured to support stator wires.

A motor assembly in which magnetic attraction between the magnets and the base of the motor is reduced by providing increased magnetic reluctance. This is achieved without the need to increase the overall height of the motor assembly, thus making the motor assembly particularly suitable for use in applications with tight space constraints and power consumption limitations.
摘要:
The present invention is a motor housing. The motor housing includes a centrally located rotor. The motor housing includes a stator having a plurality of stator teeth and a plurality of stator slots radially and symmetrically arranged about the rotor. Each stator tooth is spaced apart from each other by one of the stator slots. The motor housing also includes at least one printed circuit component deposited in at least one stator slot.
摘要:
A base plate of a disc storage system including an interior and an exterior surface, an entrance hole passes between the two surfaces and a groove surrounds the entrance hole and reduces the passage of air along an interface between the exterior and the interior surfaces. The groove may be in the shape of a circle or other alternative shapes such as a rectangle, as considered within the plane of the interior surface. An overmold is molded to the base plate and fills the groove. The plate is generally made of a plastic. The groove is amenable to the stamping process as well.
