Electronic devices and gadgets found their way to all areas of everyday life. Demand for versatile technical functionality, the expectation for performance as well as the perception of value are constantly increasing. In the inside of such devices, this leads to an increase of the number of electronic components and, with the requirement for small and wearable gadgets, their integration density: More and more functionality must be accommodated in the same or even smaller space, making necessary high request for component precision and placement during the packaging process. Just a few micrometers of component misplacement lead to different durability, a few micrometers misalignment of a phone shell lead to a lower quality perception. This necessitates consistent monitoring from the individual component to the final product. Solarius metrology systems contribute to assure quality.
