Reliability and Failure Analysis of Electronic Components and Systems

The on-going miniaturization in the microelectronics and semiconductor technologies has lead to a significant increase of requirements on electronic components and systems. Due to the complexity and variety of possible fault mechanisms, failures and malfunctions can present a serious challenge especially for SMEs. Based on their long-term experience and expertise, the scientists at Fraunhofer EMFT support their customers with a portfolio of services in the area of failure analysis of electronic components and systems, including process consulting services.

The technological know-how of the Fraunhofer EMFT experts, combined with the modern measurement and analysis capabilities, enable an extensive offering of multiparametic characterizations and qualification tests for electronic components and systems. Under laboratory conditions, simulation of physical parameters as well as measurement of reactions of components to these parameters - alone or in combination with others - is possible. Based on suitable stress tests and environmental simulations, manufacturing defects and relevant weak spots can be identified, allowing an estimation of the reliability and service life of the components and modules. 

The systematic analysis provides the fundament for respective product and process optimization at the customers’ site. Above that, destructive and non-destructive inspections enable quality assurance of manufacturing processes.
