This line of discussion is not useful.
Is it that "real hams" have to use leaded solder?
Easy there Mr Squire!
Come on! Isn't there anyone out there actually useing lead free solder in
thier circuits?
There probably aren't a whole lot. If you looked at the Kester Pages,
you can see that the other solders are at best a compromise. Lead isn't
used in solder because of some coonspiracy among Troglodyte hams, ist is
used because it works bery well. Most other solders either need a large
amount of heat, don't flow well, have poor wetting, or are brittle.
http://www.efunda.com/materials/solders/types.cfm
has a nice comparison between types
http://www.aimsolder.com/techarticle...ny%20Study.pdf
is a nice pdf regarding Antimony containig solder
Here is a page of links that has some interestinf info:
http://www.aimsolder.com/lead_free.cfm?section=articles
Especially the:
Materials and Process Considerations for Lead-Free Electronics Assembly
BOttoom line is that using tin lead solders is not particularly
dangerous from a user perspective, that it is a problem in landfills,
and that there are interesting considerations if you want to use other
types of solder.
Might as well learn all ya can!

Like I said the word 'plumber' comes from the latin plumbum meaning
lead. Ancient Rome was the first to use lead pipes. Could be why
Nero was mad as a hatter.
I heard this. Their wine was being drunk from lead-lined flasks.
Well, no, not so far as I've found. But they _did_ use lead water
piping, and they _did_ use lead acetate ("sugar of lead") as a
condiment.
The first is bad only where the water's mildly acidic.
The _second_ is Just Plain Bad.
Here is a good link on lead compounds:
