But I learned that multilayer
boards need a lot more soldering iron power than normal, and even 40W
may not melt the solder right away while 50W will.

I have an old Wen 199 gun. It doesn't state any wattage rating. Will that
do, or is it too hot?


Try it, it's really hard to overheat the ground and power plains on those
boards.
