Abstract
This paper presents, in a case study format, a methodology for combining the methods of Design of Experiments, Accelerated Testing, and Weibull Analysis to improve the reliability of an ABS Electronics Control Unit (ECU). While much literature focuses on each method individually, sometimes it's necessary combine all of these methods to achieve product improvement. The paper walks through the steps of using an multi-environment over-stress accelerated test routine, with DOE methods to evaluate key factors, and then applying Weibull and Weibayes methods to validate the new proposal and estimate expect life improvement.
