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. The fluid-based pressure compensator automatically compensates for natural and non-systematic out-of flatness tolerances of the PCB and the chip module, and non-uniform thickness of the PCB while creating a substantially uniform contact force on the LGA.

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 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： 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 electronic module and a method of assembling the electronic module. A circuit board is connected to a chip substrate by an array of connectors, and a base member is on the side of the circuit board away from the chip substrate and connector array. An elastomeric structure is placed between the circuit board and the base member. The elastomeric structure has voids between a first defining plane adjacent the circuit board and a second defining plane adjacent the base member, with the voids adapted to permit local deformation of elastomeric material in the structure. The method includes applying a compressive force between the circuit board and base member to at least partially compressing the elastomeric structure to improve load equalization on the circuit board.

摘要： An integrated circuit screen printing nozzle that has a nozzle body, a first inner layer on the nozzle body, a second outer layer on the first layer, and an opening through the nozzle body, the first layer, and the second layer. The first and second layers can be an insert held within the body. The opening allows paste material to flow through the screen printing nozzle to the stencil mask. Also, the second outer layer includes a contact surface adapted to contact the stencil mask. One feature of the invention is that the first layer is softer (has a lower durometer) than the second layer. This allows the second layer to be more durable than the first layer and for the first layer to provide additional flexibility to the second layer. Therefore, the invention provides a nozzle that has the high durability characteristics of a hard outer surface with the compliance of a soft nozzle.
