    摘要: 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. For those LGA types made by molding techniques such as the metal-in-polymer type (eg. Tyco Electronics MPI, or Shin Etsu RP) or the Metal-on-Elastomer type (IBM), using molds with the desired topography provides the desired LGA topography. For those LGAs made of metal springs, cantilevers, armatures and the like, the desired topography is imposed by shaping of the buttons during or after fabrication using a sizing die with the desired topography.
