Precise measurement and control - High voltage resistors in industrial X-ray apparatus

High voltage resistors from Metallux ensure precise measurement and control in industrial X-ray apparatus.

GE Sensing & Inspection Technologies GmbH develops and manufactures amongst others high resolution phoenix x-ray 2D-Micro- and –Nano focus X-ray inspection systems, e.g. for quality control in the electronic manufacture, as well as industrial computerised tomography (micro- and Nano CT).

These are not only used in non-destructive 3D metrology and fault analysis of industrial components and assemblies but also in many scientific fields of materials research.

X-ray inspection systems can be found in many industrial sectors. 2D X-ray inspection systems are widely used to control concealed solder joints in the printed circuit board assembly; also the “interior” of castings can be revealed. Air pockets or impurities are being recognised. With the prospect to capture the interior of assemblies threedimensional, CT opens upcomplete new avenues for the analysis within the industrial quality assurance. Discrepancies regarding material composition or density are with three-dimensional inspection easily visualised and analysed. Without destroying the inspected object, exact conclusions regarding the position of pores, cracks or inclusions can be made. Also the layer composition of individual resistors can be checked. The option of high resolution micro structural analysis is also used within scientific areas like geology or materials science. Furthermore high resolution computer tomography enables 3 dimensional measurements of assemblies with complex design, could not be investigated with conventional methods, unless by destroying the assembly. In the course of industrial process control one can, for example, compare the CT- volumetric data with the CAD-Data to check on compliance of all dimensions in a simple and time saving manner.

As one of the leading corporation worldwide in the fields of micro- and Nano focus xray technology GE, especially in the manufacture of computer tomography, relies strongly on components which have a proven history of long term stability. As especially high resolution CT-Scans can last up to several hours any deviation on the recording parameters would lead to a deterioration of the CT-Results.

Metallux high voltage resistors are used in phoenix x-ray systems to measure and control the accelerating voltage. Along life stability of these resistors will result in a sharp, bright image.

The requirements for the Metallux resistors derive from the standards set as mentioned above. Any changes of the resistor value need to be extremely small under operational conditions and cannot deviate from the set value during the entire life cycle of the device / machine. To achieve these characteristics, special pastes with an excellent thermal stability and with a minimum of detectable ageing process are used.
