Hi Lee,
First Q: What is the source of this info?
Second: We have seen the incredible difference some of this 
trace-additives can make; so why not Pb. But this is really 
'undiscovered' territory.

Subject: [TN] SAC & LEAD (Pb) CONTAMINATION

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.
