Seems like a should update my tools collection:

OK, sorry for even asking. What I am currently using is an ERSA TC70.
Seems to be a bit rare, most people don't know about it, but it IS a 70W
type (so you have the power for multilayer or bigger links), and it has
temperature control (so it won't get too hot) and is adjustable, as I
said (250..375 centigrade, IIRC). It's just not electronics, but
instead, they built a thermo switch (bi-metal) into the tip.

Sounds quite nice. Again, time to update the tool set. You certainly
have to clean up the PCB afterwards, but as long as you do this with a
smaller iron... ;-)
