Robust Circuit Design Project Example

Rockwell Collins Inc. Six Sigma project achieved 6-sigma quality in two out of the three circuit responses--Rockwell Collins Inc. develops communication and aviation electronics solutions for commercial and government customers. To mitigate inherent variation in supplier manufacturing processes and ensure customer satisfaction, a team applied Design for Six Sigma to a new product design. The DMADV (Define, Measure, Analyze, Design, Verify) project team focused on a key product characteristic – a discrete input circuit – and dramatically improved the manufacturability and reliability of the product. The project achieved 6-sigma quality in two out of the three circuit responses. Moreover, the circuit is a fundamental function that will be used in many upcoming products, extending the positive impact of the design. Define Traditional electrical design methods use a single or small set of nominal values to prove design specification adherence. Such methods do not consider the real world
