BME688 expected lifetime and required service

[MartinW]

Hi, 

I'm looking at the BME688 gas sensor. Cannot find any information on expected lift time and and service requirements during the lifetime. What is expected lift time and what is the service required during the life time?

Hi MartinW,

For lifetime, we usually perform accelerated storage & stress tests according to JEDEC standards. A usual assumption is for instance is that if accelerated stress tests like HTOL and THB are passed over 1000 hours, that this corresponds to the load of 10 years in the field. However, if a 1000 hour THB corresponds to 10 years stress or more/less is something which the user has to derive from his application conditions (“mission profile”).
