摘要： A cam-action expanding standoff connector and related method are disclosed for mounting a circuit board. The standoff connector includes a body and a plurality of mounting members having interior longitudinally-extending camming portions for engagement by a cam. A cam is configured to be positioned within the mounting members in a first position in which the mounting members are not expanded against the interior of a mounting opening and in a second position in which the cam engages the camming portions to expand the plurality of mounting members against the interior of the mounting opening. Since the camming action is horizontal only (purely radial), practically no vertical forces are applied to the circuit board and a best-fit alignment between a circuit board and heatsink can be established and maintained.

摘要： An expanding standoff connector is disclosed including a collar having a slit through a wall of the collar, a tapered interior surface and an exterior surface configured to engage an interior of a mounting opening of the circuit board. A fastener including a threaded portion and a substantially cone shaped portion configured to mate with the tapered interior surface of the collar is placed within the collar and advanced to expand the collar to mount the circuit board. A related method for mounting a circuit board is also disclosed. Since the expansion is horizontal only (purely radial), a more uniform radial expansion from top-to-bottom of the collar is applied to the circuit board and a best-fit alignment between a circuit board and heatsink can be maintained.

摘要： A flexible plate for securing a microchip surface to the surface of a cooling device. The flexible plate allows for z-directional movement between the microchip subassembly having a circuit board and a semiconductor substrate, and the cooling device. The flexible plate is a compact, single piece design that provides constraints in alignment in the x-, y-, and theta-directions, while allowing for z-direction compliance and tilt compliance. The flexible plate has tabs for mounting the microchip subassembly and tabs for mounting the cooling device. The microchip tabs are opposite one another and the cooling device mounting tabs are opposite one another. The flexible plate is a one-piece construction made from sheet metal, plastic, or metal castings. The flexible plate has a band with all the tabs mounted on the inside of the band, or one set of tabs mounted on the outside of the band.

摘要： An IC chip package and related method are disclosed. The IC chip package may include a printed circuit board (PCB) coupled to a chip module by a land grid array (LGA) connector, a metal stiffener including a fluid-based pressure compensator contacting an underside of the PCB, and at least two couplers for coupling the metal stiffener to the chip module, with the PCB and the LGA connector therebetween.

摘要： A fixture and process for assembly of semiconductor modules. Each module comprises a substrate and a cover attached to the substrate. The fixture comprises a baseplate adapted to accept the substrate and a spring-loading device containing a shape memory alloy spring engaging the cover. The shape memory alloy spring exerts a lesser force at room temperature and an elevated force at the bonding temperature of the bonding agent used to attach the cover to the substrate. The process comprises the steps of (a) loading she module into an assembly fixture and aligning a shape memory alloy spring over the module at room temperature; (b) placing the fixture and module into a heating chamber; (c) heating the fixture and module to a temperature sufficient for bonding and above the shape memory alloy spring transition temperature range so that the spring exerts an elevated force on the module; and (d) cooping the fixture and module below the transition temperature so that the spring exerts a lesser amount of force on the module, and disengaging the springs at the lower temperature.

摘要： Methods, apparatus and assemblies for enhancing heat transfer in electronic components using a flexible thermal pillow. The flexible thermal pillow has a thermally conductive material sealed between top and bottom conductive layers, with the bottom layer having a flexible reservoir residing on opposing sides of a central portion of the pillow that has a gap. The pillow may have roughened internal surfaces to increase an internal surface area within the pillow for enhanced heat dissipation. In an electronic assembly, the central portion of the pillow resides between a heat sink and heat-generating component for the thermal coupling there-between. During thermal cycling, the flexible reservoir of the pillow expands to retain thermally conductive material extruded from the gap, and then contracts to force such extruded material back into the gap. An external pressure source may contact the pillow for further forcing the extruded thermally conductive material back into the gap.
