Electrical connection method and connection site

A method for producing an electrical connection between a flexible printed-circuit board constructed from first and second insulating layers and at least one metallic conductor track there between, and a metallic mating contact member, comprising forming a light-radiating opening in a first insulating layer;

• forming a connecting opening opposite the light-radiating opening in the second insulating layer;
• bringing into bearing contact a connecting section of the metallic mating contact member dimensioned with the metallic conductor track through the connecting opening, wherein the connecting section has a lateral dimension that is smaller than the width of the connecting opening;
• and forming a welded or soldered joint by heating the conductor track and of the connecting section by a laser light directed through the light-radiating opening.
