ABSTRACT:
A method for producing an electrical circuit between a flexible circuit board (1) is described, with single-sided access and a metallic contact partner (8), such that the contact partner (8) reaches the metallic conductor strip (4) of the circuit board (1) through an access opening (6) in the unit. The circuit board (1) is thus irradiated with laser light (9) in a region opposite the access opening (6) causing a welded connection between the contact partner (8) and the conductor strip (4) to be formed.
