Abstract:
In a method for producing a module strip (200) with elevations (240) in an electrically conductive layer (230) arranged on one side of the module strip (200), first a carrier layer (220) and the electrically conductive layer (230) are provided. A stencil foil (300), which has clearances (310), is also provided. The stencil foil (300) is then fed together with the carrier layer (220) and the electrically conductive layer (230) to a continuous laminating press (100). The electrically conductive layer (230) is in this case arranged between the stencil foil (300) and the carrier layer (220). The carrier layer (220) is bonded to the electrically conductive layer (230) in the continuous laminating press (100) in a continuous process to form the module strip (200). In this process, the electrically conductive layer (230) is pressed into the clearances (310) in the stencil foil (300), whereby the desired elevations (240) are obtained in the electrically conductive layer (230).
