Abstract:
1. A method for producing a flexible planar circuit configuration (FS) having multiple layers forming a layer sequence (SF), in which an intermediate/adhesive layer (HS) is created on a substrate surface (OS) of a rigid substrate (SW), at least one first insulating layer (N at least one first conductive layer is created over the first insulating layer (N a conductive structure (L a flexible planar circuit configuration (FS) comprising the at least one first insulating layer (N wherein: the intermediate/adhesive layer (HS) is created in such a way that at least one inner area (ZB) and an edge area (RB surrounding the inner area (ZB) are defined on the substrate surface (OS) of the substrate (SW), the intermediate/adhesive layer (HS) being only provided outside the inner area (ZB), the first insulating layer (N the flexible planar circuit configuration (FS) is created directly over the inner area (ZB) of the substrate (SW) with no adhesive layer in between, whereby the flexible planar circuit configuration (FS) can be easily detached from the substrate (SW), because the inner area (ZB) over which the flexible planar circuit configuration (FS) is formed is not adhered to the substrate (SW) by the intermediate/adhesive layer (HS).
