i'm scared of the magic cancer smoke

[–] [email protected] 16 points 2 weeks ago (3 children)

Just get the lead free solder and no clean flux, it's much less cancer

[–] [email protected] 8 points 2 weeks ago (1 children)

is it still magic tho

[–] [email protected] 9 points 2 weeks ago* (last edited 2 weeks ago)

Oh 100% magic. And SMT hot air soldering is voodoo magic

[–] [email protected] 4 points 2 weeks ago (2 children)

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

[–] [email protected] 6 points 2 weeks ago

Interesting, I haven't heard about that.

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.

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?

[–] piecat 4 points 1 week ago (1 children)

Fumes don't contain lead, it's not nearly hot enough. Those fumes are flux burning.

[–] [email protected] 1 points 1 week ago (1 children)

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.

[–] piecat 1 points 1 week ago (1 children)

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.

Sure but it works well enough if you have just a little skill.

[–] [email protected] 3 points 1 week ago (1 children)

Or just use an extractor.

[–] [email protected] 2 points 1 week ago

Yeah that's the real answer...
