## Abstract

The invention relates to an apparatus (1) for examining test bodies (P), in particular electronic subassemblies and electronic devices, comprising at least one radiation source (2) for X-raying at least one test body (P), at least one detection unit (3) for detecting radiation (S) emitted by means of the radiation source (2), at least one holding element (4) for holding the at least one test body (P) and for positioning the latter between the radiation source (2) and the detection unit (3), and a movement unit (5), coupled to the holding element (4), for moving the holding element (4), wherein the movement unit (5) is constructed as a parallel-mechanism movement unit.

## Claims

### Claim 1

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.

### Claim 2 (depends on 1)

The apparatus as claimed in claim 1, wherein at least in the area which is provided for the at least one test body to be arranged, the at least one holding element comprises a material that is transparent to the x-rays radiated by the at least one radiation source.

### Claim 3 (depends on 1)

The apparatus as claimed in claim 1, wherein at least in the area which is provided for the at least one test body to be arranged, the at least one holding element comprises a carbon fiber composite material.

### Claim 4 (depends on 1)

The apparatus as claimed in claim 1, wherein the at least one radiation source is an X-ray source.

### Claim 5 (depends on 1)

The apparatus as claimed in claim 1, wherein the at least one detection unit is an imaging detection unit.

### Claim 6 (depends on 1)

The apparatus as claimed in claim 1, further comprising at least one control unit, wherein the movement unit, the at least one radiation source and/or the at least one detection unit can be controlled automatically by the at least one control unit.

### Claim 7 (depends on 6)

The apparatus as claimed in claim 6, further comprising at least one input unit coupled to the at least one control unit for the pre-definition of a respective direction of movement for the movement unit.
