Apparatus for examining test bodies

An apparatus for examining test bodies, in particular electronic subassemblies and electronic devices, comprising:

• at least one radiation source for radiating x-rays toward at least one test body;
• at least one detection unit for detecting x-rays radiated by the at least one radiation source;
• at least one holding element for holding the at least one test body and for positioning the at least one test body between the at least one radiation source and the at least one detection unit;
• a movement unit, coupled to the at least one holding element, for moving the at least one holding element;
• and
• a base;
• wherein the movement unit is constructed exclusively as a parallel-mechanism movement unit;
• wherein the parallel-mechanism movement unit is a tripod, quadruped, pentapod, hexapod, or heptapod that comprises legs, wherein each leg of the legs comprises at least two sub elements, wherein the at least two sub elements comprise a first sub element and a second sub element, wherein the first sub element includes a first joint and a second joint;
• wherein the first sub element is respectively coupled to the at least one holding element by the first joint and to the second sub element by the second joint;
• wherein the second sub element is fixed to the base in a fixed location and the second joint is fixed to the second sub element such that the second joint can be displaced on the second sub element in the longitudinal direction.
