  • Patent number: 12028978
    Abstract: An elongate, three dimensional, conductive, micro lattice truss structure has parallel layers of resilient strands so that the truss structure maintains structural integrity during end-to-end compression which shortens its uncompressed length. The resiliency of the micro lattice truss structure enables the truss structure to return to substantially its uncompressed length when the compression is removed. The truss structure is adapted to provide a resilient electrical connection between two opposing conductive areas on parallel spaced-apart printed circuit boards when the distal ends of the truss structure engage and are compressed between the two areas.

  • Patent number: 11924964
    Abstract: Devices and methods are described for reducing etching due to Galvanic Effect within a printed circuit board (PCB) that may be used in an electronic device. Specifically, a contact trace is coupled to a contact finger that has a substantially larger surface area than the contact trace. The contact finger is configured to couple the electronic device to a host device. The contact trace is electrically isolated from the rest of the PCB circuitry during a fabrication process by a separation distance between an exposed portion of the contact trace and an impedance trace. The contact finger and the exposed portion of the contact trace are plated with a common material to reduce galvanic etching of the contact trace during fabrication. The contact trace is then connected to the impedance trace using a solder joint.

  • Patent number: 8878072
    Abstract: A method for forming a frame attachment interconnect between a substrate and a frame is disclosed. The method can include applying a composite material (e.g., epoxy-glass prepreg) to a surface of a substrate. The composite material can have one or more holes disposed to substantially align with a corresponding pad on the surface of the substrate. A metal disc is placed in each hole of the composite material on top of the corresponding pad. A frame member can be placed on top of the composite material and the metal discs. The frame member can have one or more pads disposed to substantially align with the metal discs. The substrate, composite material, metal discs and frame combination can be cured in a controlled atmosphere that can include a vacuum and a predetermined temperature to create discrete electrical connections between adjacent pads but with each encapsulated and electrically isolated.
