BGA memory module with self-contained battery pack

Abstract

A battery pack for two 2032 batteries includes a molded plastic base having an upper surface on which the batteries are received and columnar standoff posts projecting from a bottom surface, as well as a molded plastic housing sized to receive the batteries and an upper portion of the base and having ears through which screws are passed to be received by press-fit threaded inserts mounted on an integrated circuit packaging substrate and tightened to a predetermined torque. Like terminals of the batteries are joined by a welded plate, with conductive pins connected to each plate extending through the base and projecting from a bottom surface of the battery pack. A mounting guide ensures connection of proper pins to corresponding receptacles during mounting of the battery pack on the integrated circuit packaging substrate.
