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?
I've never used a soldering gun, but I've read that a gun normally has
to be rated for 2-3 times as much power as an iron for the same amount
of heat.
