Thick Film: Quality assurance in hybrid technology

The task
Thick film printing is one of the most important steps in hybrid production. In this process, demand for lower failure rates and higher robustness of the modules has increased tremendously. Therefore, in order to meet present quality standards, highly accurate measurement of production parameters is crucial.These include printed resistor layers, conductor paths and laser trim structures. As of now, measurement with tactile instruments after the baking process is still the most common method to determine these parameters, but it is time-consuming and depends on the operator who has to visually analyze the results.

The solution
The LaserScan and AutoScan provide the operator in production with the ideal tools for thick film measurement. Their innovative sensors and modular software concept allow for fast, automated measurement of film thickness and other production parameters, including freshly printed paste. Thereby fast and precise control of the screen-printing machine is made possible, as for instance by automatically generating an SPC chart.
The Viking desktop tool offers a cost effective solution for mid range accuracy needs.
