Anything else would not be solder!

I am looking into the possibility of buying a kit to assemble, but have
come across this statement in the warranty Ts and Cs:

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
The use of acid-core solder, water-soluble flux solder, or any corrosive
or conductive flux or solvent will void this warranty in its entirety.
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

My current reel of no-name solder is several years old, and I have no
idea whether it complies or not (but I suspect not).

What kind of solder should one use these days?

While lead free solder is the norm now...

The use of solder with lead is still permitted for...

Private use.
Repair of circuit boards that have leaded solder on them

and a few other situations that I can't recall.

Lead based solder looks likely to be on the market for some time to come.

Find out whether the components are RoHS compliant.
If they aren't, your old solder will do.
If they are, you'll need lead-free solder.

I thought it was the other way round - leaded solder is ok with all
component types but lead free solder shouldn't be used with components
where the leads have lead in the plating. All the manufacturers I've
checked with say leaded solder is ok with RoHS compliant parts.

From a compliance point of view, you can't mix either type, either way
around. If you use leaded solder to assemble (or repair) an RoHS
compliant device, it won't be RoHS compliant.

I don't think there is any practical reason why you cannot use traditional
lead based solder on RoHS components, is there? Its just another barmy EU
regulation to make our lives difficult. There may be aguements the other way
round - lead free solder requires a significantly higher temperature and
components which are not specified to work with it could be damaged during
assembly - I guess...

It's all down to interfering busybodies who demand that anything considered
harmless must be curtailed. Fumes from leaded solder especially in a
confined area can be considered highly toxic and if 'sniffed in' in large
amounts can send you loopy at best and kill you at worst. Therefore RoSH was
dreamt up by someone with far too much time on their hands to try to make
everyone's life safer.

Makes you wonder why they don't concern themselves with the biggest killer
of all time.. smoking.. well, the answer to that is simple... MONEY.

I didn't know Beanie done a lot of construction? And, considering we
haven't heard from him in a while.... hmm?

Of course - from a practical viewpoint, it will work fine.

From a compliance viewpoint though, you end up with a product labelled
to the effect that it does not contain lead (or other harmful
substances), that does in fact contain lead.

Shirley the fumes are from the flux, not the solder?

RoHS is to address heavy metals in post-consumer waste re-entering the
environment via landfill sites.

Yes - I meant my comment only about the metallurgy of the joint. As I
understand it, private individuals aren't expected to abide by RoHS and it
won't be applied to personal (as opposed to business) sales.
