5 Steps of Reliability Prediction
How ALD reliability models calculate system MTBF efficiently:
Step 1
Component Selection
Define active/passive electronic component family and part types.
Step 2
Prediction Standard
Apply Siemens SN 29500, MIL-HDBK-217F, Telcordia SR-332, or FIDES.
Step 3
Operating Profile
Specify ambient temperature and environmental stress profiles.
Step 4
Stress Factors
Calculate thermal (πT) and electrical (πU) stress multipliers.
Step 5
MTBF & FR Output
Obtain cumulative failure rate (FIT) and MTBF prediction results.
