You don't need to vaporize lead to form lead oxide.

The first page of this link you shared mentions lead oxide:

> During the soldering process in the form of lead filler metals, lead oxide fumes are formed and excessive exposure to lead oxide fumes can result in lead poisoning.

It also says:

"Because of the relatively low temperatures in electronic soldering, fumes from these metal constituents themselves are not normally a concern"

> are not normally a concern

Seems like a squirrely way of saying that it might be dangerous, but nobody has been inclined to check.
