Zusammenfassung:	The present invention comprises a printed circuit (30) having a three-dimensional surface capable of conforming to a contoured surface of a vehicle trim panel. Printed circuit (30) comprises a plurality of electrical conductors (34) and connectors (36) secured to a polymeric substrate (32). A convoluted region (58) of the printed circuit permits formation of the three-dimensional surface (60) in the printed circuit (30). The present invention further comprises a method of producing three-dimensional surface (60) and the printed circuit (30) by either thermoforming the printed circuit (30) or mechanically stretching the printed circuit (30) to produce the three-dimensional surface (60). L'invention porte sur un circuit imprimé (30) à surface en 3D pouvant s'adapter à la surface en relief d'une garniture de véhicule. Ledit circuit (30) comporte plusieurs conducteurs électriques (34) et des connecteurs (36) fixés à un substrat (32) de polymère. Une zone en accordéon (58) du circuit imprimé permet d'y créer la surface (60) en 3D. L'invention porte également sur un procédé d'obtention de la surface en 3D et du circuit imprimé (30) soit par thermoformage, soit par étirage mécanique dudit circuit (30) de manière à obtenir la surface en 3D.
