Abstract

In a flexible circuit, a minimal force electrical and mechanical connection of a male pin connector is achieved directly to a single layer of a flexible polyimide film substrate having a thickness in the range of 0.002 to 0.012 inches. The flexible circuit has a female connector including a pattern smoothly cut in the film substrate by a CO2 laser defining pie shaped foldable flaps normally restricting passage through the flexible film at the pattern. The foldable flaps deflect when receiving the male connector in wiping engagement to solely secure the male pin connector to the substrate. The female connector further has a trace coating of an electrically conductive material on the substrate having a contact land area surrounding the pattern and extending over the foldable flaps to provide electrical contact between the trace coating and the male pin connector.
The connection requires no solder to mechanically and electrically maintain contact integrity.
