Abstract: The present invention provides a reliable high current connector for connecting the ground and power planes of a first PCB to the ground and power planes of a second PCB. The power bus bar is comprised of a first conductive structure having a first and second surface, a second conductive structure having a first and second, and an inner insulative structure positioned between the first surface of the first conductive structure and the first surface of the second conductive structure. A fastening means, inserted through openings in the conductive structures, provides a secure, low resistance electrical connection from the first or second conductive structure of the bus bar to the electrical traces of the PCB. The high dielectric constant of the insulator provides distributed capacitance between the first conductive structure and the second conductive structure, lowering the AC impedance.

Abstract: A flex cable pad on pad terminal structure is shown having raised connector pads formed using a rigid stiffener with raised features or bumps formed integral with the stiffener; aligned with the connector pad surfaces; and laminated to the flex cable surface opposite the surface presenting the exposed connector pad surfaces, to create raised contact pads that are not subject to relaxation over time when subjected to high contact normal forces. The use of a metal stiffener which has been coined to produce the raised features aligned with the contact pad locations and lamination using a film or layer of thermocuring adhesive affords an economical process and assembly technique that also effects hot deformation of the flex cable at the contact pad locations.
