- Creation of test concepts for PCB assemblies in the development stage, partly in cooperation with customers and preparation of test instructions and test specifications- Customer consulting in the optimization of test procedures and test configurations- Construction of test adapters based on test systems or stand-alone systems as well as the creation of test programs for these test systems (mainly Reinhardt- Testers), these test programs partially receive information from the μP on the module-Creating, adapting and maintaining electrical test stations for the In-Circuit test (ICT) and Functional Test (FT) (software and hardware) based on customer specifications-Maintenance, calibration, diagnosis and repair of test stations and adapters

Investigation of Spin-Valve Systems with the Scope to Develop a Reproducible Microfabrication Process- Sputter deposition of metallic nanolayers on wafer level- Development of GMR spin valves and GMR multilayer field sensing structures- Realization of 2-D sensitivities in full bridge configuration- Geometric sensor patterning on wafer level by Reactive Ion Etching (RIE)- Measurement of Magnetoresistance of the sensor stacks in the bridge and realizing the sensitivity of the Meander structures.

Evaluation of Physical and Chemical Methods for Improving the Debundling of CNTs in Aqueous Dispersions - A comprehensive literature study on the basics of solubilisation and CNT dispersion preparation, with emphasis on aqueous media, and the characterization of CNT dispersions (especially UV-Vis-NIR, Zeta-Potential, AFM).- Derivation of Figures of Merit (“degree of debundeling”) to characterize the degree of separation of the CNTs in aqueous dispersions and methods to measure them.- Experimental verification of the degree of debundeling achievable with anionic surfactants (SDS, DOC and SDBS) depending on the absolute concentration, implementation of data analysis routines especially for UV-Vis-NIR spectra (peak fitting, reduction of scattering background, using Origin, Excel).- Identification and evaluation of potential surfactant sets to realize dispersions of CNTs with a high degree of separation.- Design of a workflow and execution of own processing experiments with these surfactant sets including proper characterization to obtain an optimized degree of CNT debundeling.
