Resilient micro lattice electrical interconnection assembly

An assembly in which electrical interconnections are made among parallel, spaced apart, printed circuit boards (PCBs) comprising:

• a first PCB with a conductive area on its surface;
• a resilient, conductive, three dimensional, micro lattice truss with a first end attached to the conductive area and a second distal end opposing the first end;
• the micro lattice truss extending about an axis perpendicular to and outward from the first PCB;
• a second PCB having &conductive area on a surface facing the first PCB;
• the micro lattice truss being in a compressed state when the second distal end of the micro lattice truss engages the conductive area on the second PCB 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 conductive area on the first PCB and the conductive area on the second PCB;
• 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 layer 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.
