A method of characterizing an organic substrate including a plurality of circuit layers is provided includes the steps of: receiving an image of the organic substrate, the image including a geometric description of the circuit layers of the substrate; segmenting the substrate into multiple processing regions based, at least in part, on geometric coordinates of circuit structures defined in the image of the substrate; generating a circuit layer image corresponding to a selected one of the processing regions of the substrate; identifying one or more geometric features in the circuit layer image; estimating at least one thermomechanical property of the circuit layer image as a function of the identified geometric features; repeating the steps of receiving an image, generating a circuit layer image, identifying one or more geometric features in the circuit layer image, and estimating at least one thermomechanical property of the circuit layer image until all circuit layers in the substrate have been processed; and generating a 3-D representation of the selected one of the processing regions of the substrate including the plurality of circuit layer images as a function of the at least one thermomechanical property of each of the plurality of circuit layer images.

A system for mounting a hard disk enclosure (HDE), includes a casing pivotably mounted to minimize at least one of settle-out dynamics, external rotational vibration, and emitted vibration, the casing allowing the HDE to rotate substantially freely, wherein the center of gravity of the HDE is substantially the same as a pivot point of the casing. Further, a computer chassis includes a housing, at least one disk drive assembly for being housed by the housing, and a plurality of theta-mounts integrally built within the housing.

A heat transfer assembly includes a printed circuit board assembly supporting an electronic component assembly including one or more semiconductor chips. A heat sink assembly is adapted to be placed in thermal engagement with the one or more semiconductor chips. Included is a loading assembly for loading the one or more semiconductor chips toward engagement with the heat sink assembly. An encapsulating mechanism is provided that contains a sufficient amount of a thermally conductive medium to transfer heat between a surface of one or more of the semiconductor chips and the heat sink assembly, wherein the thermally conductive medium fills any gaps or space between the one or more semiconductor chips and the heat sink assembly.

A magnetic disk drive is provided with clamping rings that whenever nested will form an annular chamber to accommodate a toroidal ring which is deformable. As the clamping rings are progressively forcefully engaged by the clamping rings, the chamber is reduced in height and transmits the force of the top clamping ring to the bottom clamping ring in a uniform distribution and prevents the force of the bottom clamping ring from having non-uniformity of distribution. This action prevents magnetically recordable disks of the disk drive from being subjected to point loading and consequential warping. The uniform distribution exerted on glass disks also prevents cracking or shattering of the glass disk and prevents warping of non-glass disks.

A data storage device 12 includes a disk 14 having a surface zone 14a for storing data, and an access head 18 mounted on a slider 20 for writing data to and reading data from the data zone. The head 18 flies across the data zone 14a to access selected data tracks during spinning of the disk. And, the slider 20 seeks a predetermined shock buffer zone 30 atop the spinning disk, where critical data is not stored, during an idle mode for confining thereto any shock induced contact between the slider and disk surface.
