Tribology for electrical interconnection technology

Optimization of contact surfaces, reliability and efficiency

Tribology is crucial for the performance of electrical connections because it influences the interaction of friction, wear and contact mechanics. Fraunhofer EMFT uses digital twins to analyze tribological properties on a macro, meso and micro scale in order to optimize contact surfaces. The aim is to increase the efficiency, reliability and lifespan of electrical systems and to develop customized solutions for a wide range of applications.

We use digital twins to analyze electrical connections on three levels:

Macro level: Investigation of the influence of individual contacts on the entire assembly in order to develop thermomechanically and electrically optimized designs.

Mesoscale: Evaluating the mechanical properties of specific connections, including contact forces, deformation and relaxation behavior.

Microscale: Analysis of material properties such as surface roughness and microstructure to accurately predict contact resistance and wear.

The combination of these scales provides a comprehensive picture of electrical connections and enables more precise developments, optimized tests and greater reliability in a wide range of applications.
