Three-dimensional electronic circuit support structure, as well as circuit carrier unit comprising the circuit support structure as a function component and three-dimensional circuit arrangement consisting of at least two of such three-dimensional circuit carrier assemblies

The invention relates to a three-dimensional electrical circuit support structure having at least two interconnected planar, two-dimensional substrate plates having contact-making and are equipped preferably on both sides with electronic components, wherein the substrate plates form substrate plate walls which are arranged at an angle <180 ° with each other, resulting in a three-dimensional space shaped body having open spaces resulting between the substrate plate walls and wherein electrical conductor means are advantageously provided which conduct electric current from a substrate plate wall to an adjacent substrate plate wall and a Schaltungsgrundtager having such an electrical circuit support structure, and a three-dimensional circuit arrangement, consisting of at least two of such three-dimensional circuit carrier constructions.
