The ongoing trend towards miniaturization, higher integration as well as cost efficiency will make it necessary to investigate a new assembly method for micro components. In this paper, a novel method of fluidic-based micro assembly is presented. A self-assembly effect which is caused by the predominant surface tension and structured surfaces is used to position droplets and to align microchips. Results from numerical analysis and simulations were evaluated and completed by experiments made in cooperation between the IFF-MST University of Stuttgart and the Fraunhofer IPA.
