Warpage issues during the processing of System in Packages (SiPs), by means of Fan-Out Wafer Level Packaging (FO-WLP), is still a challenging task. The differences in thermal expansion coefficients of the dissimilar materials, as well as the cure-shr

The combination of continuous miniaturization of electronics and the demanding reliability requirements for industrial and automotive electronics is one big challenge for emerging packaging technology. One aspect is to increase the understanding of t

This paper considers the optimal operation of an oil and gas production network by formulating it as an economic nonlinear model predictive control (NMPC) problem. Solving the associated nonlinear program (NLP) can be computationally expensive and ti

The focus of this study concerns the thermo-mechanical understanding of prepreg materials during the lamination process in order to predict the correct warpage behavior of a multi-layer stack-up, and with that, the corresponding mechanical stress sta

A combined damage model has been built by the use of degradation models and finite element simulations as physics-of-failure method to determine degradation rates. This approach has some advantages over the more common Coffin-Manson approach like the

Local sensitivity information is obtained for KKT points of parametric NLPs that may exhibit active set changes under parametric perturbations; under appropriate regularity conditions, computationally relevant generalized derivatives of primal and du

Kurzfassung Zuverlässigkeit ist für moderne technische Produkte eine Grundvoraussetzung für den wirtschaftlichen Erfolg. Bedingt durch die hohe Komplexität der zumeist mechatronischen Systeme und die vielfältigen Abhängigkeiten muss heute ein e

LED luminaires are already beyond retrofit systems, which are limited in heat dissipation due to the old fitting standards. Actual LED luminaries are based on new LED packages and modules. Heat dissipation through the first and second level interconn

To fulfil strict emission regulations and the need for higher efficiency of future Diesel engines require an optimized combustion process. Optical investigations represent a powerful tool for getting a better understanding of the ongoing processes. F

Further miniaturization of electronic systems is approaching new limits due to the failure mechanism of electromigration. Electromigration results in a transport of material in solder joints subjected to high electric current densities. This decrease
