Masters / Project thesis: Simulation of an X-ray imaging process for solder joints and utilisation of the results for machine learning based volume measurement

Schech Ann-Katrin

The exact quantification of filling levels of special solder joints proves to be a particular challenge in electronics production.

Within the scope of this work, an evaluation procedure is to be developed on a test circuit board, which can determine the filling level of a given, exemplary solder joint on the basis of a single X-ray image.
First of all, the image acquisition of simple, exemplary soldering structures shall be simulated. The resulting image data will then be used as a basis for a programme for the evaluation of real image data.

For this purpose basic knowledge in image processing and Python programming is necessary and can be acquired during the work.
