If it was saturation the current intake would be high and the 2N7002
FETs would attempt to unsolder themselves.
yeah well, that would help out in the replacement process
Not always, I've seen device leads that have gotten so hot that they seem
to weld to the pad or via. A soldering iron won't melt the lead (or
whatever it's become).
The old solder is oxidized. I've found that adding some fresh solder
(With a mild RMA flux) helps disolve the old crap.
Our processes are all RoHS, so I do the same. The first thing I do
when soldering a part is add leaded solder to the socialist solder. I
usually take the excess off with some solderwick.
I would hardly call adding leaded solder to a joint a RoHS process. How
certain are you of only leaving the allowable 0.1% lead in a repaired
