Abstract
A flexible printed circuit is electrically connected to a printed circuit board or the like without the use of intermediate conducting contact elements. The flexible printed circuit has conductive strips thereon each terminating in a conductive pad. The pads and the areas of the insulation sheet of the circuit underlying the pads are deformed to provide contact projections defining cavities therebelow. A backing layer of elastomeric material underlying the insulation sheet embodies points which extend into the cavities. The flexible printed circuit is clamped against the printed circuit board causing the elastomeric layer to be compressed so that the points fill the contact cavities to produce a high-force localized contact between the contact projections and the traces on the printed circuit board. A multi-layer, flexible printed circuit arrangement is also disclosed.
