Hi, My nephew is 10, mad keen on electronics. What minimum age do people
think is appropriate for owning a soldering iron?




I started at 13

Did a few kits but most of them were a bloody mess
with bad solder joints but practice did make things
better.

Despite bad eyesight and the fact things take longer
for me to do I still occasionally do a small project
here and there when I can.

But like other people have said why is lead used in solder?

Why haven't they come up with something else?

They have , but some are a lot more toxic than lead.
You won't get lead poisoning but other possibly worse health effects.
I prefer to risk the lead poisoning.

Also lead free has a higher melting point.

Same with non rosin flux , lot more likely to cause asthma
the ones with halogens

Similar to replacing lead in petrol. The replacements are a lot more toxic
and cause cancer
but don't cause lead poisoning.

A few manufacturers are starting to use conductive adhesives
especially in Europe with the tougher environmental and safety regs.
More non-repairable equipment.

Also helping with the push for distributed passives.
PCB has the passive components built-in as part of the pcb.
Only for massive runs.

Seriously there is an alloy with identical crystal
structure to tin/lead in the way it solidifies etc,
but it's 40% platinum. It's not marketed as solder though
more of a lab curiosity and it has a nasty tendency to
shatter like glass with mechanical shock.

not to mention the shock from the price ...

I think most of us who replied are glad to see a kid learn to build stuff, and
acquire useful skills instead of just watchin tv and gameboying etc.

And it is great to see a kid being given support and encouragement -
