Packaging and Interconnection Technologies of Power Devices, Challenges and Future Trends

Authors: Raed A. Amro


Standard packaging and interconnection technologies of power devices have difficulties meeting the increasing thermal demands of new application fields of power electronics devices. Main restrictions are the decreasing reliability of bond-wires and solder layers with increasing junction temperature. In the last few years intensive efforts have been invested in developing new packaging and interconnection solutions which may open a path to future application of power devices. In this paper, the main failure mechanisms of power devices are described and principle of new packaging and interconnection concepts and their power cycling reliability are presented.

Keywords: Reliability, Power electronics devices, Power Cycling, Low-temperature joining technique (LTJT)
