Splitting a Product for HALT Focus

Abstract

Kirk and Fred  discussing underwater drones and how we divide up a product to most efficiently apply HALT to subsystems before applying stress to the whole product

Key Points

Join Kirk and Fred as they discuss ways that they have split up a product for HALT when there are known limitations of mechanical subsystems controlled by electronics
Topics include:

• Mechanical systems may have temperature or vibration limitations, such as a spinning hard disk or tape/tape head interfaces, that solid state electronics will operate at much higher temperatures in HALT
• Power supplies in HALT can be loaded with static loads but this may not show what dynamic loads occur during product use that can show up as weaknesses in HALT
• The best HALT is done when the product can be divided and HALT can be applied to separate subsystems inside the environmental chamber but run against the rest of the actual system which may be outside the chamber.

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.
