Surface inspections have long been standard in the automotive sector. Measuring the paint layer thickness of a component is a special task, since non-destructive measurement is difficult. For this purpose, a random sample of the batch is mechanically divided in order to then be able to carry out the necessary measurements and tests. Tested parts are therefore to be marked as scrap even if the measured values ​​are within the tolerance. The measurement of a complete layer structure takes place via terahertz contactless in seconds,

where the thickness of each individual layer is output as a separate measured value. At the same time, the radar transmission and the radar reflection can be output for each individual layer and for the overall structure. Measurements can be made with an accuracy of up to 0.1 µm or 0.1 dB, which means that even minimal deviations from the target value become visible. All layers that are optically transparent to terahertz radiation, such as plastics, adhesives, conductive coatings, etc. can be measured,

whether they are complex structures of paint structures is irrelevant. In contrast to conventional methods, terahertz technology allows a faster and more adequate solution for testing a component, which takes place without any damage to the component. While Helmut Fischer GmbH thus provides a suitable process, thanks to our more than 25 years of experience in the field of measurement and testing technology, we also take care of the hardware development and optimal integration of the components in your company.
