For systems that…may experience some degree of vacuum…it’s common to use lead solder still because it doesn’t tin whisker so unfortunately it’s still around for some of the stuff I’ve worked on.
Leaded is objectively better for everything except health/pollution. Which is the point of RoHS.
Leaded solder has a lower melting point, flows much better, easier to visually see bad solder joints, and doesn’t form whiskers. Also less brittle, so cracked joints are less likely.
i’m scared of the magic cancer smoke
Just get the lead free solder and no clean flux, it’s much less cancer
is it still magic tho
Oh 100% magic. And SMT hot air soldering is voodoo magic
Yeah lead free solder is perfectly fine.
Where I live, lead solder is even illegal to sell and buy unless you have a permit which is impossible to get for individuals
Interesting, I haven’t heard about that.

Lead free sucks ass and you can pry my leaded solder from my cold dead hands.
Seriously just wash your hands.
What about the fumes?
Fumes don’t contain lead, it’s not nearly hot enough. Those fumes are flux burning.
That’s good.
But I still don’t get why someone would willingly use lead when lead free works great.
I mean the RoHA for example exist for good reason.

Sure but it works well enough if you have just a little skill.
Or just use an extractor.
Yeah that’s the real answer…
