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.
