Abstract:
A semi-finished product for the production of a printed circuit board having a plurality of alternately arranged insulating layers and conductive layers and at least one hard gold-plated edge connector is characterized by the hard gold-plated edge connector being arranged on an inner conductive layer of the semi-finished product and being fully covered by at least one group of an insulating layer and a conductive layer. The inventive Method for producing a printed circuit board having a plurality of alternately arranged insulating layers and conductive layers and at least one hard gold-plated edge connector, where an outer conductive layer is surface treated, is characterized by the steps of providing a hard gold-plated edge connector on a group of an insulating layer and a conductive layer, covering the conductive layer and the hard gold-plated edge connector with at least one group of an insulating layer and a conductive layer, surface-treating an outer conductive layer to form connector pads for wire bonding of electronic components, cutting the insulating layers and the conductive layers down to the conductive layer forming the hard gold-plated edge connector, removing the insulating layers and conductive layers from the hard gold-plated edge connector. The inventive printed circuit board comprised of a plurality of alternately arranged insulating layers and conductive layers and at least one hard gold-plated edge connector is characterized by the hard gold-plated edge connector being arranged on an inner conductive layer of the printed circuit board, and the inner conductive layer forming the hard gold-plated edge connector protruding from the plurality of insulating layers and conductive layers.
