This paper presents a systematic study of sintered silver. In order to investigate the correlation between processing conditions, microstructures, thermal and electrical properties, sintered silver samples have been prepared in 27 variations of sintering temperature between 200°C and 270°C and sintering pressure between 5 MPa and 25 MPa. For the thermal and electrical characterization, the innovative test stand LaTIMA has been used. The microstructures of the samples have been analyzed by focused ion beam (FIB) and scanning electron microscope (SEM). The results of the thermal and electrical characterizations as well as the structure analysis showed clear correlation to the process conditions of sintered silver.
