摘要:
A heat spreader, comprised of a plurality of carbon fibers oriented in a plurality of directions, with a carbon or metal matrix material dispersed about the fibers, is described. The carbon fibers facilitate the spreading of heat away from the smaller semiconductor device and up to a larger heat removal device, such as a heat sink.
摘要:
An electronic package includes a heat-generating electronic component such as an integrated circuit chip, a thermally conductive member, which may be an integrated heat spreader, and a low modulus thermal interface material in heat conducting relation between the electronic component and the thermally conductive member. Increased thermal performance requirements at the electronic component level are met by the thermal interface material, which includes a polymer matrix and thermally conductive filler, which has a storage shear modulus (G′) at 125° C. of less than about 100 kPa, and which has a gel point, as indicated by a value of G′/G″ of ≧1, where G″ is the loss shear modulus of the thermal interface material. The values for G′ and G″ are measured by a strain-controlled rheometer.

Liquid crystalline epoxy compounds, compositions including the compounds, and methods of using the compositions are disclosed. In one aspect, an epoxy compound may have a melting point that is less than 140° C. and may be liquid crystalline at a temperature greater than 150° C.
摘要:
A latch assembly connecting a leg of a table to a table top comprises a housing assembly comprising a housing and a cover, a pivot mounted on the housing and pivotable between an upright position and a pivoted position, wherein the pivot defines an upright slot and a pivoted position slot, a remote release mechanism located remote from the pivot outside the housing assembly and movable from a first position to a second position, and a slider connected to the remote release mechanism and movable in response to movement of the remote release mechanism. When the remote release mechanism is in the first position the pivot is locked with respect to the housing assembly in one of the upright position and the pivoted position, and when the remote release mechanism is moved to the second position the pivot is movable between the upright position and the pivoted position.

Formulations and processes for forming wafer coat layers are disclosed. In one embodiment, an organic surface protectant is incorporated into a wafer coat formulation deposited onto a semiconductor wafer prior to the laser scribe operation. Upon removal of the wafer coat layer, the organic surface protectant remains on the bumps and thereby prevents oxidation of the bumps between die prep and chip and attach. In an alternative embodiment, an ultraviolet light absorber is added to the wafer coat formulation to enhance the wafer coat layer's energy absorption and thereby improve the laser's ability to ablate the wafer coat layer. In an alternative embodiment, a conformal wafer coat layer is deposited on the wafer and die bumps, thereby reducing wafer coat layer thickness variations that can impact the laser scribing ability.

Method of forming solder bumps of an integrated circuit package is described. A solder paste is formed from a material having a characteristic that the deposited instances thereof substantially retain their geometric shape upon exposure to electromagnetic radiation.
摘要:
A method of making an electronics substrate is provided. A material is deposited on a base component. The material has a first composition and includes a polymer. A pattern is imprinted into the material by contacting the material with a die and moving a profile of the die into the material. The material is then modified while being held in the profile of the die to cause at least partial curing of the material due to a change in composition of the material from a first composition to a second composition. The die is then removed from the material. Electric conductors are then formed in trenches of the pattern.
