Abstract:
A flex cable presenting a pad on pad connector assembly comprising:a terminal portion of said flex cable which includes a series of contact pad locations at one surface of said flex cable;an adhesive layer adjoining said terminal portion of said flex cable at the surface opposite said one surface; anda rigid stiffener which presents integral rounded embossed projections respectively aligned with said series of contact pad locations and is laminated to said flex cable surface opposite said one surface by said adhesive layer to form raised pad on pad contact locations, whereby such raised contact pad locations provide initial point contact and resist relaxation over time when subjected to high contact normal forces,wherein said rounded embossed projections are each formed as a spherical cap embossment on a metal stiffener surface and form a contact pad surface which makes a high pressure point contact with a cooperating planar pad,wherein said rigid stiffener is formed of a rigid metal selected from the group consisting of aluminum, stainless steel and mixtures thereof and is coined to form said rounded embossed projections.
