Abstract
The object,—to create a printed circuit board for an implant having improved properties in connection with the electrical contacting via the contact points of the conductor tracks on the printed circuit board,—is achieved, according to the present invention, by means of a device for contacting and/or electrostimulation of living tissue cells or nerves with having a printed circuit board having with at least one contact point for electrical contacting, the printed circuit board encompassing comprising a flexible multilayer system with at least one conductor track. In accordance with the invention, the contact points for the conductor track in the multilayer system are galvanically reinforced. To this end, a galvanically reinforced layer is grown onto the already preprocessed contact point, for example by means of a galvanic process. By virtue of the application of one or more additional material layers onto the contact points of the conductor tracks, these latter are mechanically more stably anchored in the printed circuit board in mechanically more stable manner and hence become more reliable in their function.
