Homebrew PCBs

Unfortunately we need to follow the regulations to create the products. 
I read the article yesterday and was quite impressed - they still do not 
know the cause of the whisker growth. What was interesting is that the 
growth has been known since the 1940's. The chart of using various 
solders based on the situation is a good reference. And the point that 
lead, in general, is non-soluble; so where vapors could be generated or 
wiped off and into one's mouth, etc, lead is restricted - paint and 
gasoline are examples. But withing packaged semiconductors and on coated 
PC boards, tough to get the "lead out". :-)
