Yes I know it is eutectic. But for newbies the lower temperature is much
easier on the board, one tends to lift fewer foils this way. It's also
much easier with a decent soldering station to not lift foils, but if you
don't have such, a lower melting point means the newbie tends not to overdo it.
Of course, if you are soldering some heavy duty backplane, which I believe
was the start of this thread, I suppose it's not as much of a problem.
But I'd still recommend not using lead/acid solder for a backplane. ;-)
