CALCE is working with Turkish multinational commercial goods manufacturer Arçelik A.Ş. to develop a qualification procedure for electronic components that are to be used in several household appliances. The vision of Arçelik includes adopting best practices in science and engineering in product development and support.
CALCE and Arçelik A.Ş. first use the standards-based qualification as a guide for developing a qualification procedure and physics-of-failure-based qualification to identify the most pressing needs for component qualification. CALCE and Arçelik A.Ş. also proposes improving component qualification procedures by applying diagnostics and prognostics techniques to data gathered via real-time monitoring of product behavior while completing each qualification test. The use of diagnostics and prognostics techniques in qualification is called prognostics-based qualification. Applying diagnostics techniques helps identify anomalous behavior exhibited by the product at that time or even predict anomalous behavior before the behavior even occurs. Using prognostics techniques enables the prediction of “remaining useful life” for the product undergoing a qualification test to determine if the product will experience failure before the qualification test is complete. By predicting anomalous behavior before it occurs and estimating the “remaining useful life” of a product undergoing qualification, one may reduce the time required to complete the entire qualification procedure and verify if the product would pass the qualification requirements or not. Reducing the time needed for qualification reduces the costs associated with qualification, promoting a quicker time-to-market. Additionally, prognostics-based qualification would provide an opportunity to identify the operating parameters that best represent the state of product health, thereby reducing the complexity of the real-time parameter monitoring apparatus and reducing the costs of tracking product behavior. Ultimately, the use of prognostics-based qualification in conjunction with standards-based qualification and physics-of-failure-based qualification provides additional opportunities to analyze product behavior and may reduce the required time for and expense of completing the qualification procedure.
