How to Prevent NDF Returns

Abstract

Kirk and Fred discuss what we can do during product development before shipping a product that will help reduce warranty returns that seem to have no identifiable failure mode.

Key Points

Join Kirk and Fred as they discuss the continued challenge of no defect found warranty returns.

Topics include:

• The costs-benefit trade off for the development of more specific diagnostics to better isolate the real cause or component failure.
• How developing stress operational margin in a system helps improve tolerance to manufacturing and use variations
• Why thermal stress can stimulate the variation of signal timings that result from component and system assembly

Enjoy an episode of Speaking of Reliability, where you can join friends as they discuss reliability topics.

Join us as we discuss topics ranging from design for reliability techniques to field data analysis approaches.
