The phoenix v|tome|x s is a versatile high-resolution system for 2D X-ray inspection and 3D computed tomography (micro ct and nano ct)) as well as for 3D metrology. To allow high flexibility, the phoenix v|tome|x s may optionally be equipped with both, a 180 kV / 15 W high-power nanofocus X-ray tube and a 240 kV / 320 W microfocus tube. Due to this unique combination, the system is an very effective and reliable tool for a wide range of applications from extreme high-resolution scans of low absorbing materials as well as for 3D analysis of high absorbing objects.
3D Computed Tomography
The classic application of industrial X-ray 3D computed tomography (micro ct and nano ct) is the inspection and three-dimensional measurement of metal and plastic castings. However, phoenix|x-ray’s high-resolution X-ray technology opens up a variety of new applications in fields such as sensor technology, electronics, materials science, and many other natural sciences.

High-resolution computed tomography (micro ct and nano ct) is used for inspecting materials, composites, sintered materials and ceramics but also to analyze geological or biological samples. Materials distribution, voids and cracks are visualized three-dimensionally at microscopic resolution.

High-resolution computed tomography (micro ct and nano ct) is widely used in inspecting geological samples, for example in the exploration for new resources. High-resolution CT-systems provide three-dimensional images at microscopic resolution of rock samples, binders, cements and cavities and help identify certain sample characteristics such as size and location of voids in oil-bearing rock.

3D metrology with X-ray is the only technique allowing to non-destructively measure the interior of complex objects. By contrast with conventional tactile coordinate measurement technique, a computed tomography scan of an object acquires all surface points simultaneously – including all hidden features like undercuts which are not accessible non-destructively using other methods of measurement. The v|tome|x s has a special 3D metrology package that contains everything needed for dimensional measuring with the greatest possible precision, reproducibility and user-friendliness, from calibration instruments to surface extraction modules. In addition to 2D wall thickness measurements, the CT volume data can be quickly and easily compared with CAD data, for example, in order to analyse the complete component to ensure it complies with all specified dimensions.

In plastics engineering, high-resolution X-ray technology is used to optimize the casting and spraying process by detecting contraction cavities, blisters, weld lines and cracks, and to analyze flaws. X-ray computed tomography (micro ct and nano ct) provides three-dimensional images of object characteristics such as grain-flow patterns and filler distribution as well as of low-contrast defects.

In the inspection of sensors and electronic components, high-resolution X-ray technologies are mostly used to inspect and evaluate contacts, joints, cases, insulators and the situation of assembly. It is even possible to inspect semiconductor components and electronic devices (solder joints) without having to disassemble the device.

To determine the number of individual strands and the crimping density, three tomographic layers, of the inlet area, the outlet area and the crimping zone itself (green), are generated: 19 strands enter, but only 17 exit the crimping zone. Due to the lack of material, small voids developed inside the crimping zone..
