Abstract:
A microelectronic assembly and a method of forming same. The microelectronic assembly comprises: a microelectronic package including a substrate and a die, the die being electrically conductively bonded to the substrate at a front side thereof and further having a backside; a cover plate defining an inlet opening and an outlet opening therethrough; bonding posts mechanically bonding the cover plate to the backside of the die; a sealant body sealingly bonding an inner periphery of a die side of the cover plate to an inner periphery of a backside of the die to form, along with the backside of the die and the cover plate, a cooling fluid chamber. The backside of the die, the cover plate, the bonding posts and the sealant body together define a microelectronic cooling device including the cooling fluid chamber and configured to receive cooling fluid through the inlet opening, to flow the cooling fluid in the chamber between the bonding posts, and to allow the cooling fluid to exit from the outlet opening to cool the die.
Abstract:
A microchannel structure has microchannels formed therein. The microchannels are to transport a coolant and to be proximate to an integrated circuit to transfer heat from the integrated circuit to the coolant. At least one of the microchannels has a length extent and has a first section at a first location along the length extent and a second section at a second location along the length extent. The first section of the microchannel has a first aspect ratio and the second section is divided into at least two sub-channels. Each sub-channel has a respective second aspect ratio that is greater than the first aspect ratio.

Abstract:
A socket comprises a socket body having a bottom surface at which the socket can be mounted to a motherboard, a top surface, and several side surfaces. The top surface has an array of electrical contacts at which a package containing a microprocessor can be coupled to the socket. One or more of the side surfaces have a slot, which includes an electrical interface at which a circuit card containing cache memory for use by the microprocessor can be removably inserted into the socket body parallel to the motherboard.
Abstract:
A method and apparatus for making a multiply folded BGA package design with shortened communication paths and more electrical routing flexibility. A package apparatus includes a substrate and a first integrated circuit (IC), wherein the first IC is electrically connected to the first face of the substrate, and wherein a first segment and a second segment of the substrate are both folded around the first IC. A second IC is electrically connected to the second face of the substrate, such that the second IC is connected to the first and second folded segments of the substrate abode the first IC.
Abstract:
An electronic package is provided, having a flexible substrate, a first plurality of conductors, and a second plurality of conductors. The flexible substrate has first and second portions with a fold portion between the first and second portions, and is folded at the fold portion to position the second portion over the first portion. Each one of the first plurality of conductors runs from the first portion over the fold portion onto the second portion. Each one of the second plurality of conductors runs from the first portion onto the second portion without running over the fold portion.
Abstract:
A thermal conducting material with higher thermal conductivity for a given low viscosity is shown. Carbon fibers are added to the thermal grease to promote thermal conductivity. The carbon fibers are also not highly electrically conductive, reducing the danger of short circuiting due to misapplication of the thermal grease. Due to the high thermal conductivity of the carbon fibers, a lower loading percentage is needed to obtain significant gains in thermal conductivity. The low loading percentages in turn permit lower thermal grease viscosity, which allows the thermal grease to be spread very thin during application.
Abstract:
The invention includes a method for assembling an integrated circuit package. In the method, a substrate is presented. Next, an integrated circuit may be mounted to the substrate. A retaining structure is presented that is shaped as a mesh that is at least one of a hexagonal mesh, a triangular mesh, and an irregular shaped mesh. The retaining structure is then impregnated with a thermal grease to form a heat pipe. The heat pipe is trimmed to the perimeter of the top surface so that the heat pipe does not extend into the at least one corner of the top surface. The heat pipe is placed on the top surface of the integrated circuit. A thermal element is then placed on the impregnated retaining structure.
