Described are enclosures that include a friction stir weld, including electronic device enclosures, and precursors thereof that contain a metal base that includes a recess and a metal cover that in an assembled condition form a joint at which a friction stir weld can be produced, as well as methods for producing a friction stir weld at a joint of such an assembly; the base includes at least one bow wave reduction feature.

Enclosures having a friction stir weld, precursors thereof having a metal base having a recess and a metal cover, and related methods

The present disclosure relates to a data storage device interior components and/or data storage device housing components that include one or more solid-state deposition layers, and related methods of applying solid-state material to said components via solid-state deposition.

Data storage devices, and related components and methods of making

Clamping devices and associated methods that are useful to develop both axial and circumferential clamping forces in response to a common axial clamping force. The clamp is able to use a simple mechanism to generate both kinds of clamping forces from a single, axial actuating force. The clamping devices of the present invention are particularly useful for clamping cover and base deck components of a hard disk drive enclosure together to allow the components to be joined and sealed together using welding techniques.

The present invention relates to methods to join at least first and second metallic components in which a pre-treatment is applied to one or more region(s) of at least one of the components to be welded together before welding takes place. The pre-treatment involves contacting at least a region of the first metallic component with a rotating and translating tool such that the rotating and translating contact locally heats, softens, and mixes successive portions of at least the region of the first metallic component. The first and second metallic components are placed together such that a joint is provided between at least the pre-treated region of the first metallic component and the second metallic component. At least the pre-treated region of the first metallic component is welded to the second metallic component along at least a portion of the joint.

Described are enclosures that include a friction stir weld, including electronic device enclosures, and precursors thereof, that contain a base and a cover that in an assembled condition form a joint at which a friction stir weld can be produced, as well as methods for producing a friction stir weld at a joint of such an assembly.

Enclosures, devices with a friction stir weld, precursors thereof, and related methods

The present disclosure relates to using solid state deposition to selectively and strategically manage one or more properties of one or more portions of a data storage device. Material deposited via solid-state deposition can be used to prepare a surface for subsequent treatment (e.g., welding), to join two or more substrates together, and/or to seal one or more joints or surfaces to control, e.g., the humidity in the interior of a data storage device. The present disclosure also involves related data storage devices.
