Abstract
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.
