Today, I read where if you added 0.5% Lead (Pb) into SAC, that the fatigue life would be reduced from 18,670 to 8,089.



Question: How would the fatigue life react with Lead (Pb) levels in SAC ranging from 0.0% (Baseline) through 1.0%? Is it a linear relationship or exponential relationship?



Thanks again.
