Abstract

Kirk and Fred discussing the understanding of HALT and the fact that many see as HALT, the finding of operational limits and weaknesses, as “just another tool in the reliability engineering tool bag” and how for Kirk it is most efficient approach to reliability development.

Key Points

Join Kirk and Fred as they discuss their different views on testing in general and HALT (which both agree should stand for “limit” and not “life” test) and how it fits into a reliability development program.

Topics include:

• What can be done functions of a reliability engineering before the complete system is available?
• Why the failures caused by manufacturing mistakes or large variations are also an important contributor to field failures, which is a reliability engineering issue, and need to be understood by engineers to make a reliable product
• The use of HASS (highly accelerated stress screen) is  an expensive process that should not be  used as a “inspection” process, and may actually decrease reliability if the the process or design creating the failure mechanism is not corrected.
• Failures are gold!

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.
