[time-nuts] Lifetime testing

[Mark Goldberg]

There is lots of work in this area. Search "accelerated life testing
electronics" and you will find lots of information at various levels.

These guys have the PhD version, but you have to pay to join or be an
academic for access.

I've worked with this in the Aviation industry for a long time. There is a
reason planes don't fall out of the sky all the time but consumer
electronics are throwaway items.

Mark
