、Failures In Time Calculation:
Use HTOL test information mentioned in section
FIT = ( x 2 (ν ,
CL )
Ⅳ, FIT (Failures In Time) can be calculated as below:
× 10 9 ) /( 2 × S × H × AF ) = ( 4 .61 × 10 9 ) /( 2 × 77 × 1000 × 280 .59 )

=106.69 (pieces per 10 hours) @ 40
℃ with 90% Confidence Level.
Where AF is acceleration factor setting activation energy to 1.0eV as zero failure.
