Abstract
This work presents the potential of Scanning Acoustic Microscopy (SAM) as a crucial non-destructive evaluation (NDE) method for process control and failure analysis of thermoelectric modules (TE-M). Thermoelectric generators (TEG) are highlighted for their ability to convert waste heat into electrical energy, offering benefits such as no moving parts, low maintenance, and long lifespan. The study emphasizes the importance of reliability engineering in transitioning thermoelectricity from lab-scale to industrial applications, focusing on the quality of thermoelement junctions. The "Dream Team Concept" of NDE methods, including IR-Thermography, SAM, and X-ray Tomography (XCT), is introduced for comprehensive analysis. The findings demonstrate that these NDE methods provide essential data for subsequent destructive analyses, ensuring the long-term stability and performance of TE-modules.
