What is the state of the art for electronics reliability engineering?
(OP)
Hello,
I am not a reliability engineer however am tasked with determining expected lifetime for a simple circuitboard in a manned space application. The supplied specs suggest but do not require HDBK-217. I have read a little about the handbook methods and it seems they are not robust or accurate. The Physics-of-Failure approach seems to be more accurate and cutting edge, but I haven't found any good practical analysis guides other than academic papers and extremely overpriced research software (CalCE requires annual membership fee of $65,000).
What is the next best practical reliability analysis method besides HDBK-217? Any good references or affordable software ya'll could recommend?
Thanks,
Matt

So bruteforce-wise, you can grab a indentured parts list and populate with the appropriate values from the database and crank out the failure rate. Note that a space application will probably require some level of redundancy, which will require some other software to plow through hardware design.

I can do absolutely anything. I'm an expert!
