Dear Sir,
we are using industrial grade -40 to 85C. not commercial grade 0 to 70C.
how can i take the quality factor as a commercial?

if i use commercial quality the failure rate is very high.

Is the established reliability quality levels is applicable only for MIL Components?
and we should not use MIL Components or commercial components in our project.

how can i reduce my failure rate.

please help me.

thanks & best regards,
