Abstract
Abstract In an electronic assembly whose components or circuit components are combined into at least two sub-assemblies or function units, one or more of the sub-assemblies or function units are disposed on a first substrate comprising a first substrate material. The first substrate is in its turn disposed with one or more further sub-assemblies or function units on a second substrate comprising a second substrate material.
