Hi,
I have good experience on MTBF calculation.
MTBF will be performed based on your requirement which environment, temp, derating as per the MIL 217F and MIL 27Plus.
We will use windchid predition software to predit the MTBF. If you want we can do with excel also.
Good experience on Circuit analysis.
Once done, I will suggest you if there is improvment need on your board/system to bring more MTBF and reduce the failure rate.
Hope you can contact me @ +91-9739430666 for more discussion.
First day - Discussion on project, understanding circuit, Derating Sheet preparation,
Second day - Tool Import sheet preparation, MTBF result obtain, MTBF value release
3rd day - Review and updation from your end. Suggestion provide
