MEOST Setup Remotely
Join Kirk and Fred as they discuss the term MEOST and how it is very similar to HALT in the use of stress to find latent defects or weaknesses.
- Gregg Hobbs was very possessive of the term HALT which he had coined for his strength limit testing, so many organizations use other acronyms to describe HALT.
- Fred’s favorite stress in HALT or MEOST is vibration on mounted components especially the ones that can move relative to each other. That condition often leads to reliability issues and is why vibration HALT is so useful for Power supplies.
- Trying to conduct or direct at HALT or MEOST in remote labs is extremely difficult if not impossible to do if the lab does not have a thorough understanding of HALT and the goals of HALT since most companies will not increase margins beyond stress specifications.
- The second question is about testing for a photo diode reliability issue. There are so many possibilities of the cause, a deep failure analysis and measurements need to be made before determining the stresses needed to screen the units.
