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.
