Abstract:
Apparatus for mounting an LGA package having a plurality of terminal lands or leads with surfaces extending in a plane substantially parallel with one face of the LGA package comprising:(a) a guide member having oppositely disposed first and second faces and a plurality of guides extending there through from said first face to said second face and arranged to correspond with terminal surfaces on an LGA package;(b) a support base having oppositely disposed inner and outer major faces and a plurality of guides extending there through from said inner face to said outer face supported in spaced relationship with said guide member so that said inner face is substantially parallel with and spaced from said second face of said guide member with the guides in said support base arranged to correspond with the guides in said guide member;(c) a bending plate having apertures therein substantially corresponding with the guides in said guide member positioned between said guide member and said support base and adapted for lateral movement with respect to at least one of said support base and said guide member;(d) a plurality of axially elongated contact fingers, each having a first free end, a second free end and an elongated shank extending between said first free end and said second free end, with the portion of said shank adjacent said first free end positioned in and constrained by a guide in said guide plate, the portion of said shank adjacent said second free end positioned in and constrained by a guide in said support base, and said shank passing through an aperture in said bending plate; and(e) means for moving said bending plate laterally with respect to at least one of said support base and said guide member to bend each contact finger, thereby increasing or decreasing the distance between said first free end and said second free end of each of said contact fingers.
