Resilient micro lattice electrical interconnection assembly

An apparatus for making a resilient electrical connection between at least one surface and a conductive area on a base board, the apparatus comprising:

• a resilient, conductive, three dimensional, micro lattice truss with a first end permanently attached to the conductive area;
• the micro lattice truss extending from the base board about an axis perpendicular to the base board, the micro lattice truss having a distal end where the distal end is adapted to engage the at least one surface;
• the micro lattice truss being in a compressed state when the distal end of the micro lattice truss engages the at least one surface and the micro lattice truss is subject to a force in an end-to-end direction, the micro lattice truss in the compressed state establishes an electrical connection between the one conductive area and the at least one surface;
• the micro lattice truss being a stack of layers where each layer contains elongated strands that have respective ends that terminate at two spaced-apart parallel planes that define boundaries of each laver of the micro lattice truss, the planes being perpendicular to the axis, each layer having the ends of the elongated strands being interconnected with respective ends of elongated strands in at least one adjacent layer, the strands being resilient and having ends that are affixed to the respective end of at least one other strand in the same layer;
• the micro lattice truss being formed of spaced apart inner and outer elongated concentric sleeves each having a resilient, conductive, three dimensional, micro lattice structure, the strands that form the outer sleeve are parallel to the axis while not in the compressed state and bow outwardly away from the axis during a compressed state, the resiliency of the micro lattice truss causing the amount of bowing away from the axis to be a maximum at the longitudinal middle of the sleeve.
