Soldering unleaded components

Graeme · Sep 28, 2004

Hi All
Simple (maybe) question. I've got a tin/lead plated circuit board, and some
components which have plated leads without lead. Is it possible to make a
good solder joint between these two? If so, what sort of solder should be
used (leaded, unleaded)?
TIA.

Have you simply tried to "tin" one of the leads with ordinary solder?
Gently heat a lead and apply flux-core solder to it. If it's solderable,
the solder will flow and coat (tin) the lead. If this works, you can just
solder it like you would any other component.

for all electrical work you need to use *rosin* core solder...

it's ok to use the standard lead/tin solder

but silver solder should also be ok

I thank you both for your comments. Are there any web-based reports that
investigate this process?

here is one of many links:

btw: be sure to use good ventilation

and to wash you hands well with soap and water after handling lead

Right, err, thanks.
I'm not after a guide on how to solder, but I'm looking for some/any
technical articles that describe the reliability of joints made between
unleaded components and leaded solder.

IN the over forty years I have used lead bearing solder, I have never seen or
heard of anyone affected by the stuff. We all learned how to handle it.

You hold the part with your left hand, the iron with your right,
and the solder in your teeth.

Buy a good circuit vise that can be tilted, rotated, etc. Best thing
I ever spent a lot of money on... had it now for probably 30 years.

Sanity at last!

I have three, on just for surface boards, one very small and one universal
holder / vise. Also, some times you clip the iron in place and feed the
solder, rolled into a plastic tube, to a part held in place with tweezers.

*Only* because you cannot get the full reel of solder in your mouth you have

to cut off smaller pieces to use - which is wasteful when they get too short
to reach the workpiece where you can see it.

However where cost is not an issue and some of the solder can be wasted (do
not swallow it - in large lumps it is liable to cause a serious
constipation) I recomment the multicore solders: 3 cores of rosin, one or
more cores of flavouring.
Raspberry is ever popular although not my personal favourite.

Many experienced 'tronics guru's swear by the deluxe solder with an
anti-bacterial mouthwash in (one of) the stripes.
Low activity rosin is recommended for those with many older type dental
fillings.

If it upsets you so greatly, Clarence, you could always wrap a large
loop of the solder tightly around your neck and feed it into the active area
by leaning forward.

I have no problem soldering. I even know how. It is ignorance that I find

upsetting, along with pride in that ignorance.

I long ago learned that if you put the solder in a tube and attach a ring to
the tube, you can apply solder to the work by moving one finger. While holding
the component with tweezers. The iron is held in the other hand.

So you have nothing of value to say and THINK your funny?

As usual, your wrong!

There are a few groups who are using the rarely reported cases of someone
actually eating old lead paint and haveing symptoms to give them some supposed
credibility. Other than the political scare tactics there is few actual reports
of anyone affected by "exposure to lead" in any form, and no reports of ill
effects to exposure to solid metallic lead as used in solder. The vapors are
flux, not lead which only becomes a hot Simi-liquid. (Plastic) No you should
not inhale flux fumes, nor tars and nicotine from tobacco!

This is a phony issue, not a real threat to any large numbers of people!

No. The main reason for not holding the solder in your teeth is so that
you can hold an air extraction tube in your mouth. Just sucking clears
away all those nasty smoky fumes which block your view. Besides, how do
you spool the reel of solder in your mouth (unless you have a lot more
dextirity than me).

However where cost is not an issue and some of the solder can be wasted (do

Trouble is, that in large quantities, the antibacterial core can harm
the useful bacteria in your mouth and gut. If you use this, you need to
remove the residue by rinsing once daily with mercury, or better yet,
cyanide. This will pretty much eliminate all problems you will
experience from having a bacterial imbalance.
