Abstract: The invention relates to a printed circuit board (10), with conductor tracks (11, 11a), which are arranged at least on a surface of the printed circuit board (10) and serve for the electrical contacting of components, and with at least one testing zone (12), which is formed by a portion of the conductor track (11) and serves for the electrical contacting of a testing element (20), in particular a testing head, wherein the surface of the printed circuit board (10) is provided with a protective layer (14), which is formed in the testing zone (12) such that it is interrupted in the region of a contact zone (15), and wherein the contact zone (15) is provided with a layer (18), which establishes an electrical contacting of the testing element (20) with the layer (18). According to the invention, it is provided that the contact zone (15) is arranged at least partially at a lateral distance from the edges of the conductor track (11) in the region of the testing zone (12).

Abstract: The invention relates to a plug connection device, comprising a plug (7) which has contacts (8) and comprising mating contacts (4) arranged on a substrate (2), wherein the contacts (8) are intended for electrical contacting of the mating contacts (4). According to the invention, the plug (7) has at least one recess (18) for accommodating an element (10) arranged on the substrate (2).
