Abstract:
A system, apparatus, and method, are provided to deposit conductive bonding material into cavities in a mold. A fill head is placed in substantial contact with a mold that includes cavities. The fill head includes a sealing member that substantially encompasses an entire area to be filled with conductive bonding material. The conductive bonding material is forced out of the fill head toward the mold. The conductive bonding material is provided into at least one cavity of the cavities contemporaneous with the at least one cavity being in proximity to the fill head.
Abstract:
In an automated library, data cartridges, such as magnetic tape cartridges, are stored in storage cells and accessed by data storage drives. An accessor with a gripper transports cartridges between storage cells and storage drives. Cartridges are prioritized according to their relative importance. A processor manages the placement of the cartridges in cells by having higher priority cartridges stored closer to the front of multi-cartridge cells than cartridges with a lower priority. Cartridges with a higher priority may also be stored closer to a storage drive than cartridges with a lower priority. A pusher may be used to push cartridges towards the front of multi-cartridge cells with an empty position to enable the gripper to reach the front cartridge.
Abstract:
A structure for cooling an electronic device is disclosed. The structure includes a top layer disposed over the electronic device. The structure further includes a plurality of spring elements disposed between the top layer and the electronic device, wherein at least one of the spring elements comprises a spring portion and a fin portion. At least one of the spring elements provides a heat path from the electronic device and provides mechanical compliance. In another embodiment, the structure further includes a heat-conducting layer disposed over the electronic device, wherein the fin portion of each of at least one of the spring elements is coupled to the heat-conducting layer.
Abstract:
A method for dispensing solder bumps on a mold plate includes the steps of: relatively moving a fill head comprising an o-ring from a first location to a second location such that the o-ring decompresses as it crosses from the first location to the second location; filling at least one cavity in the mold plate with solder; and then relatively moving the fill head from the second location to a third location such that the o-ring decompresses as it crosses from the second location to the third location. The step of relatively moving the fill head from the first location to the second location includes moving from a higher elevation to a lower elevation. A mold plate to parking location interface includes: a mold plate for holding solder; a fill head with an o-ring for dispensing solder bumps on the mold plate; a parking location for locating the fill head; and a platform between the mold plate and the parking location for relatively moving the fill head from the first location to the second location such that the o-ring decompresses as it passes over the interface.
Abstract:
A method and apparatus for providing combined radial and timing multislot self-servowrite propagation is disclosed. Radial bursts are combined with each timing mark and requires only three recovery/read-write spacing allocations per sector. The channel operates without requiring the writing of any bursts between reading radial bursts.
Abstract:
A system and method for self-servo-writing of multi-slot timing patterns is described. Individual timing marks are replaced with groups of timing mark slots. At each timing mark location, a time measurement is made by detecting a timing mark in one of the slots. Also, extensions to the existing timing marks are written in other slots. The combination of timing measurements at every timing mark and extensions to those timing marks written at every opportunity improves the overall precision of the timing propagation. The improved accuracy of timing mark placement produces a commensurate improvement in the placement of the concomitantly written servo-data. In addition, the alignment accuracy of the written pattern is less sensitive to variations in rotation speed and variations in the shape of written transitions. Moreover, only a single disk revolution is required at each servo radius to write servo data and propagate the timing marks.
Abstract:
A heat sink includes a plurality of layers being disposed substantially parallel with a surface of a heat source. The layers include a plurality of pin portions spaced apart from each other in a planar arrangement wherein the pin portions of the layers are stacked and bonded to form pin fins extending in a transverse direction relative to the heat source to sink heat. A compliant layer is disposed between the pin fins and a mechanical load. The compliant layer provides compliance such that the pin fins accommodate dimensional differences when interfacing with the heat source.
