2. Failure Rate (Refer to JIS-C-5003)
Assuming that the total test time = T (No. of test pieces ×
test time) and the No. of failures = r, the failure rate can
be calculated by obtaining r/T and multiplying it by the
numerical values commensurate with the reliability level
and the number of defective ICs.
If the failure rate (FR) is calculated from the results of
the above high temperature test of the AN6914UBS,
assuming that the reliability level is 60%;
T=150 × 16000=2.4 × 106 (hours)
r=0 comes to 0.92 at the level of 60%.
FR=0.92/2.4 × 106=3.8 × 10–7=380Fit
Assuming that activation energy is 1.0 eV, FR will be
38 Fit at worst (Ta=100˚C) because an acceleration
factor differs by about 1 digit between at 125˚C and
100˚C.
