Hitachi Energy supplies high-performance semiconductor modules for inverters in traction and industrial applications. Currently, novel power semiconductors for the drive train in electric vehicles are being developed at the Lenzburg site. For the further development of an already existing small production line to one with higher production capacities and a higher degree of automation, a 6-month thesis offers the opportunity to gain a deep insight into an exciting production development project and to make a significant contribution to the success of the next project phases. The thesis is about the benchmarking of the existing process for sinter paste application and especially the analysis after printing, so called Sinter Paste Inspection (SPI). After analyzing the existing process and already generated data, the phase of improvement starts. In this phase, based on historical data and several DoE’s, the improvement of the Sinter Paste Analysis step can start, as well as the optimization of the paste application process itself. In depth understanding of the process and setup is needed to review and challenge the preliminary process parameters. The underlying project proposal will have a real-life application and will be an important contribution to the overall production development. Duration of the thesis: 6 months, start 1th of December 2021.
