Abstract
For a method for producing a flexible circuit configuration in the form of a layer sequence of at least one insulating layer and at least one conductive layer, typically multiple insulating layers (N1, N2, N3, NF) and multiple structured conductive layers (L1, L2), the layer sequence for the flexible circuit configuration is deposited on a rigid substrate so that the adhesion of the layer sequence with respect to the substrate is less in an inner area, in which at least one, preferably multiple flexible circuit configurations are created, than in an edge area (RB) which surrounds the inner area (ZB). An intermediate layer can advantageously be deposited for this purpose in the edge area, which causes a stronger adhesion of the layer sequence over the edge area than the inner area, which is not provided with an intermediate layer.
