Hi Joel,
If all SnPb solder joints reach 205C thay all will be fine. The problem is
that in most assemblies the differences in T are quite large, and if some SJs
only reach 217C their proper metallurgical bond is not a sure thing. I do not
know what you imply with "he majority of the solder joints on the balance of the
board are getting too hot?" There are no negative consequences to this--I am
much more concern ed about PCBs and components getting too hot. That is where
I see most of the problems with LF-soldering.
