Low thermal EMF solder

[Dave M]

Does anyone have a source for low thermal EMF solder? I'm only looking for
a 1/4 or 1/2 pound spool.

What are you soldering to what? If it's a part lead to a PC board, or a wire
splice, it doesn't matter. As long as the connection blob is isothermal, any
thermoelectrics depend on the incoming/outgoing alloys of the leads, and not the
solder.

the magic recipe is 85% lead and 15% tin. That's approximately the
mixture of solder used to repair copper/brass automotive radiators
(before RoHS). You might ask at a radiator shop or an antique car
restoration buff.

I found one source:

There are probably more.

If you have an electric solder pot, propane furnace, or home foundry,
you could make your own solder out of pure tin bars and some old lead
fishing weights.

That's low EMF against copper.

The effectiveness depends on the physical characteristics of whatever
he's soldering. If there's no temperature difference across the
copper to solder boundary, there should be no thermocouple effect.

Googling, I find that the recommended solder mix is 70% cadmium and
30% tin. Impossible to find today and rather dangerous. It also
bring back an old nightmare. I would get a roll of the stuff with
rebuild kits for bolometer RF power sensors. Lots of dire warning
attached to the roll of solder.

When one of the engineering techs tested high positive for cadmium
poisoning, the company had everyone involved get a blood test for
heavy metal poisoning as well as cadmium. My cadmium and lead levels
were rather high but not excessive. At the time, I thought I had
caught a cold or flu that would not go away. It turned out that it
had something to do with my handling and testing NiCd batteries and
possibly the cadmium loaded repair solder. Not much could be done
except to take zinc supplements and avoid further exposure. It took
about 6 months to shake the cold. In the meantime, I discovered that
crimping the bolometer leads with a brass ferrule produced less
temperature related issues than with the cadmium solder. Anyway, I
strongly recommend NOT using the Cd70/Sn30 solder mix.

Also depends on the allowed error level, because nothing is truly
isothermal, especially if there are any active components.

The active components have internal aluminum or gold wirebonds that have huge
thermoelectrics against silicon and against the leadframe material.

If you solder an IC lead - maybe alloy 42, maybe a copper alloy if you're lucky
- to copper traces on a PCB, the inherent thermoelectrics of that will blow away
any effects of a little solder. The gradient across the solder will be
microkelvins, picovolts.

What sort of errors are you budgeting? What's the signal represent?

The best thing to do to keep thermal noise and offsets down is to put a cover
over the sensitive stuff and a fat copper plane below it, to keep it isothermal,
and keep local power dissipation gradients low. The effects of solder will be
way, way below other thermal offsets.

Google links are huge for some reason. There's a shorter "real" link under there
somewhere, or use TinyURL.

I'm repairing a couple of old Holt 323A Audio Voltage standards. The
thermocouple circuitry requires a low EMF solder (specified in the manual,
and contained cadmium). The insstrument was sold with a hank of the right
solder inside, but has long since been used or lost in someone's toolbox.

I've tried using several formulae of solder, but nothing I've tried will
allow the themocouple InAmp to behave. I used to repair & calibrate this
same model back in the late 60s and 70s, and remember that the proper solder
had to be used or the thing drifted all over the place. Thus, I'm back to
looking for the "right stuff".

Thanks for those who've suggested alternatives. I'll keep trying untill
something works,

Cheers,
Dave M

If you can reduce the 'fit' of the conductor to the hole it is being
soldered into, the cross sectional thickness of the solder is reduced,
and thereby its factoring in this equation. No?

IOW, is there any way to insure that the 'gap' between the conductor
and walls of the hole it is being soldered into is minimal?

[Spehro Pefhany]

These guys in India list it (70:30 Cd:Sn), bottom of the page.

Would be interested to know what/whether they quote for a small
amount. I know others have had success in getting reasonable
quantities of special alloy wires from India.

http://www.marutimetal.com/solderwire.htm

Sn and Cd are not particularly expensive metals.

Here's a possible source for Leeds and Northrup "thermal free solder"
PN 107-1-0-1. According on one reference, it's 70% Cd, 30% Sn.

Some interesting reading on thermal EMF:
<http://cds.cern.ch/record/1246516/files/p143.pdf>
Looking at Table 4.10, it seems that pure silver and pure gold have
the same thermoelectric potential as cadmium/tin solder. Too bad
silver melts at about 900C which would require welding instead of
soldering.

I don't think Simon still maintains MT-Newswatcher, as the last update
to the webpage was in 2006.

I'm not the original poster, so I don't know his application.

But I do know that low-EMF solder is widely used for low-level
measurements. For instance, thallium copper used to be used in place of
pure copper, if memory serves. Doesn't seem to be used anymore, from
google searching.

I agree with Spehro, Cd content doesn't seem to be an issue. I
purchased a
while ago some non-superconductive soft solder from Kapp, no problems.
They
don't seem to carry Cd-Sn, however. Neither does the Indium
Corporation of
America, which otherwise has a wide selection of alloys available.

For nntp client, is some kind of authentication or login required? Port 119?

[Jasen Betts]

For gmane no signup or auth is needed. news.gmane.org port 119
you can read the lists on gmane.org for free.

volts-nuts is

gmane.comp.volts.nuts

there's a gmane FAQ somwwhere


If you want to post to the mailing list gmane will attempt to do that
for you, but your post will probably be blocked by the list manager unless
you sign up for the list, (you can signup and then access the list control

Yup. There's also a time-nuts list for those that might be interested.

Slight distinction, ad driven rags. The quality on those publications
fell through the floor in the 1970s.

ED and EDN are fading. I measure them with calipers and sometimes get down below
35 mils. The optics and microwave mags are still fat and have good articles and
ads.

I just flipped through Electronic Design. Total blather, but fortunately not
much of it. Just took a couple of minutes.

This "Volt-Nuts" thing is different than the magazine known as "Nuts
& Volts", which is what I errantly thought he was talking about
originally.

The former is a far more precise realm than the latter. Or was
designed to be so at least. Whether that is true or not...

Agent really is pretty good, however i am running it in wine, as well as
the browser FF3.6.10 and while neither one is perfectly compatible with
wine, both run fairly well. Making changes to my main server which is
hosting these apps is a serious issue and not undertaken lightly. Top
that off with remote access through SSH and troubleshooting gets rather
opaque. Do you want to step up to the plate?

what does agent do when you click a link? When I click the links in the
ltspice about window wine launches a native linux browser. If you can
customise the action agent takes there's probably a setting taht will
suit...

That is ok for cases where there is an eternal program call, like LTSpice,
where there is a customizable command line. It does not work so well for
installed plugins, like flash or acroread. Plus there is the rock and a
hard place issue of no newer plugins for the old browser and the old
plugins are having more problems with newer formats. All that fights with
a server system which is required to be stable, warts and all.

I didn't customise anything, and upon looking I cant see any options.
I suspect it just uses whatever is set in the registry as the default
browser.

that appears to be "winebrowser" (from ~/.wine/system.reg )

[Software\\Classes\\http\\shell\\open\\command] 1221793096
@="C:\\windows\\system32\\winebrowser.exe -nohome"

when I do

wine winebrowser http://google.com

winebrowser somehow figures out that chromium is my favourite linux
browser and uses that to open http://google.com

probably doing a find-and-replace on the wine registry files ans
replcing firefox with winebrowser will enable the use of a native
browser.

How do they do it? It seems that C:\\windows\\system32\\winebrowser.exe
is a magic name. The actual file contains no object code whatsoever.

I can't immagine why anyone would want the acroread plugin...
neverthelesee both plugins are available for linux.

If you can't install a recent browser on the linux side that could be a
problem.

I am also trying hard to find low thermal emf solder... Anyone knows any alternatives for Cd70Sn30?

There's rarely a reason to use low thermal solder. What's your situation?
