  • Patent number: 7975379
    Abstract: LGA connectors are fabricated with buttons or spring contacts preformed to different heights to accommodate the initial topography of a typical module or PCB of a particular product type. This is accomplished during fabrication by measuring topographies of mating surfaces of a first electronic device and of a second electronic device; fabricating interposer contacts to form opposing non-planar sides having respective inverse topographies for contacting the mating surfaces; and sandwiching the interposer between the first and second electronic devices with the opposing sides in contact with respective mating surfaces.
