Symmetrically mating the first and second metal sheets in opposing relation to each other to form upper and lower bumps each defining an enclosure therebetween wherein the mated first and second sheets form a contact structure. Coating the contact structure with an insulating material, and fabricating helix shaped contacts from upper and lower bumps. The helix shaped contacts having first and second portions being in mirror image relationship to each other.
Abstract:
A low insertion force connection using two interfitting components: a tapered element (85) and a beam element (83) which is deformed by the tapered element in the region where the primary forces are buckling, rather than bending. The present invention is based on pressure engaged insert/receptacle type of connections that are self-assembling, and require a minimized insertion force to produce a high and tunable contact force that is not applied through the component (82) to be attached. Apart from differences in size, the same design principles are applicable from the chip level to the board level of a microelectronic system. The invention comprises a low cost pressure engaged electrical and thermal connection, based on insert/receptacle structures in which the contact force and insertion force are separated. Such a design allows tunable contact force while it minimizes the insertion force and allows also for self-assembly and reworkability. They can readily be used in area array configurations and in conformal 3-D electronic packaging structures in all connection levels of a microelectronic system.

Abstract:
A substrate mating assembly has a first substrate (10) with at least one socket (14) mounted thereon. The at least one socket has contact retention points (30) provided thereon which extend into a contact receiving opening (24) thereof. A second substrate (2) is provided with at least one mating contact (6) mounted thereon. The at least one mating contact (6) has an arcuate surface and is dimensioned to be received in the contact receiving opening (24) of the at least one socket (14). As the first substrate and the second substrate are electrically mated together, the at least one mating contact (6) is received in the contact receiving opening (24) and maintained in position therein by the cooperation of the contact retention points (30) with the arcuate surface of the at least one mating contact. The contact retention points are provided on resilient arms (26) which are configured to allow for the elastic distorsion thereof as the at least one mating contact (6) is brought into engagement with the at least one socket (14), such that when the at least one mating contact is fully inserted, the resilient arms (26) will return toward an unstressed position to cooperate with the arcuate surface of the at least one mating contact to maintain the at least one mating contact in position.
Abstract:
A device comprises a surface mount component on a substrate, in which the surface mount component is attached by a set of discrete mechanical coupling parts and by a bonding layer. This enables the mechanical coupling properties and the electrical/thermal properties to be optimized separately.
