Abstract:
An apparatus for cooling electronic devices to be used in the vacuum of space is described. a window frame is provided as packaging for an electronic device having a substrate and a chip. The window frame includes an opening to allow a heat pipe to be in direct contact with a backside of the chip. The window frame is hermetically sealed to the backside of the chip. The window frame is also welded to a kovar ring located on the backside of the chip to provide a hermetic seal between the window frame and the substrate.
Abstract:
An electronic device package includes a substrate and wire columns arranged in groups about a neutral stress point of the substrate. The height of the wire columns is substantially uniform for the plural groups of wire columns, and a length of at least one of the wire columns is greater than the uniform height. A method of fabricating an electronic device package having a column grid array includes applying two templates on wire columns of the column grid array and bending at least one wire column to increase its length while maintaining a uniform height for the column grid array. In another aspect, an electronic device package substrate includes wire columns having at least one non-uniformity in lengths of the columns, and the length of a wire column corresponds to a distance of that wire column from the neutral stress point of the substrate. The non-uniformity of length in the wire columns reduces stress in the package leads after attachment of the package to a carrier substrate, such as a printed circuit board.

Abstract:
A method for manufacturing an electronic multi-chip module that involves stacking at least six tested devices to form the module. These devices may be individually tested prior to assembling the electronic module. After individually testing the devices, the devices may be stacked one on top of the other to form an electronic multi-chip module having at least six stacked devices. Other embodiments may be described and claimed.
