ABSTRACT:
A connector for mounting an LGA device on a circuit board comprises a film contact having electrode bumps on inner ends of respective conductive paths at predetermined spaced apart locations corresponding to respective locations of the individual electrode lands on the LGA device and is clamped extending across a central cavity defined between housing base and frame members. A flat elastomeric biassing pad having a series of upstanding, closely spaced resilient projections is retained by the base member in the cavity with the projections supporting spaced apart locations of one surface of the film contact while a cover member retains the device in the cavity in the frame member with the respective lands thereof pressed against respective electrode bumps, compressing the biassing pad to assure sufficient contact pressure. The cover member has a camming detent which progressively engages the device during closing, moving the device across the film contact with a wiping action.
