Abstract

Kirk and Fred discussing the common question in empirical limit testing (a.k.a HALT) that many design engineers have. How strength margins above specifications are important for long term reliability.

Key Points

Join Kirk and Fred as they discuss the challenging question of “why worry about failures above specification?”.

Topics include:

• Informal fault tree analysis on how the GoPro camera that was lost on a recent trip and potential failure modes that the could occur
• Most users of commercial electronics are probably not aware of the actual published environmental specifications, and  don’t care, just that it works.
• Where and when to stop increasing the strength of the product when conducting a HALT process during development

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.
