[SI-LIST] Re: SSO of a Spartan3 in a PQ208 package

I think a note of caution is in order here.  After using PbSn solder to 
reflow a board in a toaster oven,  DO NOT use that toaster oven to heat 
food.  The vapors of lead will deposit themselves on the interior 
surface of the oven and will subsequently contaminate food.  Even if one 
were to use Pb-free solder, I would be wary of reusing the oven to heat 
food.
