dc.description.abstract The most time consuming and capital intensive portion in the assembly of power electronic devices is the test system. A comprehensive test system including functional and stress screening technologies can significantly increase assembly times and more than double the capital investment required in a new assembly line. The primary purpose of the test system is to screen components for early life failures and to verify proper assembly. Determination of key performance characteristics and the resultant test system are developed during the product design phase and are seldom revised after the product has been released to manufacturing. This thesis explores best practices in testing methods and develops new methods to analyze test system performance. Both efforts were conducted in an effort to optimize existing test regimes. Upon completion of the above analyses the existing test sequence was reduced by 50%. This was primarily due to a discovery in the Burn In test cycle which indicated that failures correlated strongly with the on/off cycles inherent in the test sequence. A new test cycle was proposed to accommodate this finding and test results verified the initial hypothesis. Additionally, the summary of best practices identified new forms of product testing including Highly Accelerated Stress Testing (HAST), moving additional product testing into the development phase consequently reducing testing requirements during assembly. en_US
