Abstract:
A printed circuit board to module mounting and interconnecting structure comprising:a. a printed circuit board having a top surface; b. a plurality of electrical contacts on said printed circuit board top surface; c. an interposer having upper and lower surfaces; said interposer lower surface positioned on said printed circuit board electrical contacts; d. said interposer further defining a plurality of apertures projecting from said upper surface to said lower surface, each of said apertures aligned with one of said contacts; e. a module having a bottom surface, said bottom surface having a plurality of electrical pads, said pads positioned on said interposer upper surface, each pad aligned with one of said apertures; f. a plurality of deformable resilient electrical conductors having top and bottom ends, each of said conductors disposed within one of said apertures with each said conductor top end pressing against one said aligned pad and each said conductor bottom end pressing against one said aligned contact, each of said conductors thereby compressed and exerting an upward normal force of at least about 30 grams against said pad and a downward normal force of at least about 30 grams against said contact, said conductor thereby electrically connecting said engaged pad to said engaged contact; and g. a clamping means connected to said printed circuit board and said module, said clamping means applying force to said printed circuit board in an upward direction and thereby forcing said contacts against said conductor bottom ends and said interposer lower surface, said clamping means further applying force to said module in a downward direction and thereby forcing said pads against said conductor top end and said interposer upper surface; wherein said conductor may deform laterally responsive to lateral movement of said printed circuit board relative: to said module and maintain the upward normal force of at least 30 grams and the downward normal force of at least 30 grams.
