Subject: Reliability Prediction
I did a reliability prediction several days before.This system consists of about 10~15 PCBs,and there are average 500 components on each PCB.I used 217F and Bellcore respectively.MTBFs are 5800h and 40000h.Is that reasonable? After that,I saw a reference about similar system of other company(a famous company).In that reference,they claim their system'MTBF is 1000 years(failure rate is 111 fits).Oh my god!Is that possible?Or am I wrong?
