Lots of folks will be willing to accept a better way, if there is a good
reason given for it (but equally ready to reject a new way, if it's
presented without reason).

What's the university's reason?

I re tin mine with Kester Ultrapure Tip Tinner.

You better get an e-mail off to Weller and Ungar right away..... many of
their soldering stations (and other brands too) come with a tip cleaning
sponge.
It works for me.... and has been working just fine for many decades.
And please enlighten me...... why should "we" never use a wet sponge?
thermal shock? corrosion? Just think of the thermal shock when pressing
the hot tip against a cold joint...... not to mention the corrosion
possibilities from electrolytic capacitors that have leaked on the pcb, etc.

I use a stainless steel pot scrubber stuffed into the bottom of my iron
holders. It cleans the tips everytime you put the iron into the holder.

Cheap and most effective, my favorite kind of solution.

I use one of those tip cleaners that looks like a brass brillo pad.
It cleans even the worst looking tips without cooling them down and
lasts much longer than a sponge. It's also nice not to have to wet
the sponge every day.

I once had someone try to tell me (this forum?) that harmful fumes would be
given off from synthetic sponges. I don't believe it myself. About all
that gets 'burned' is the water the sponge is periodically soaked in. The
sponge itself doesn't even get scorched if kept well hydrated.

I just use paper towel, dry.

A sponge is handy because it can fit into the well intended for it
in the soldering iron stand. But if it's not wet, at the very least it
burns when you touch it with the iron, and it can be rather stiff. If
you want it to last, I suspect that's why it's damp.

Since paper towel is really cheap, it doesn't matter, and it is handier
not to have to keep something damp.

But nobody can tell you whether a wet sponge is a bad idea unless you also
tell us why the university thinks so. At the very least, the statement is
ambiguous, because it's not clear whether it's the wet, or the sponge,
that they consider the problem.

Keep in mind that most tips do last a long time. At least, if you use plated
tips. If you don't use plated tips, the tips will corrode, and often fairly
fast, and no amount of cleaning will fix that.

You wipe plated tips not to prevent damage, but to get off the excess solder,
and the rosin that collects there.

Why would I pay $8.79 + shipping and have to have another item on my bench

I have a portable iron I keep in my service case for in home work; it doesnt
have a "well" for a sponge, so I use a "wipe away", made by Fort Howard. Looks
like a really heavy duty paper towel, but it must be some kind of treated
paper, cause it doesn't burn when I wipe the tip with it; one will last me
about 6 months before it gets too cruddy looking.

a wet sponge serves several uses during the soldering process..
1-it helps to keep the tip of the hot iron clean by ..quickly..moving
the tip across the sponge surface..this simple act causes the
impurities to be rubbed off the tip..
2-it acts to temporarily reduce the tip temperature to prevent harmful
vapors to continue burning from the tip tremperature
3-it promotes clean and shiny solder connections..which help to
prevent contaminated solder joints..

Aluminum (aluminium) oxidises very easily, even when not heated, and
you also need special flux and solder in order to "tin" (or rather
plate) the tip so that it can efficiently transfer heat to the solder
joint. I can't see this metal being at all useful for soldering tip
construction.

You mean solderin iron tip? I rarely clean it with that solder sucking

And its probably best for desoldering.

My thinking is the opposite of wetting, instead the aluminum alloy tip
stays dry and only serves to transfer heat to the work. Then the
solder/flux is applied to the work to absorb the solder and not the

I have a block of wood with a piece of suede leather glued to it. It
make a nice firm surface for me to remove excess solder as well as
clean off the oxide. This beats cleaning the tip on the lab coat or
trousers. Then there is the wet sponge of course.

There just could be a little difference between "desoldering" & "soldering"

Why don't they make tips out of aluminum alloy? I shaped a small Al tip
to remove 8 pin ics and it seems to work fine without corroding at all.

Looking at the price of soldering iron cleaners, I decided to roll my
own so I got some small cellulose sponges and a small disposable aluminum
bread pan at the local hardware store. A little bit of work with the
scissors, and I'd figured I'd saved about 5 bucks over the thing at
the electronics store.

But after the first day there was some strange reaction between the
solder refuse, the aluminum pan, and the damp sponge that ate holes
right through the aluminum in one night.

The aluminum pan got replaced with a square glass votive candle holder
(looks like a cubical highball glass).

I'm surprised, but if you say that it has worked for you then I'll

In general, getting the solder to wet both the tip and the work is the
essential part of transferring heat to the work. Heat transfer without
wetting is much poorer and is quite often insufficient for the job.

That is indeed what happens when a copper tip goes dry. The oxide film
seems to be a very effective barrier to the heat transfer. By
comparison, with Aluminum its oxide is only molecules thick and good
metal to metal heat transfer occurs at the slightest application of
pressure. From my experience, it did work well for desoldering but
I'll have to experiment soldering with a thick Al tip. Maybe a
slightly different method can be made workable, in contrast to the
usual soldering common sense of wetting the tip and the work.

I guess what you're saying is that a wetted tip gives you a "positive"
meniscus while a non-wetted tip produces a "negative" meniscus. The
"positive" meniscus obviously produces a much larger surface area
across which heat can be transferred from the iron to the solder.

I never thought of it quite this way before, but it makes sense.

Yes, I specifically mentioned the good heat transfer. The most

extremely thin (only 1 or 2 molecules thick), and is easily broken.
One reason for this thin layer is due to Al's high oxidation state.
A peculiar thing I noticed was the solder clung to the Al edges in
tiny clumps appearing a bit like thick cold butter.

I'm not arguing against wetting in the usual method but since it
doesn't happen with Al then its good heat transfer might be key.
Well, I'll just have to try it for myself and see, won't I?
I just recalled where I might have a length of #12 Al wire...

Just one point -- because aluminum is so common, and known to have such good
heat transfer, the notion of its use in a soldering tip is not even
remotely "non obvious," to borrow a Patent Office term.

That (to the best of my knowledge) none of the world's soldering iron
manufacturers offers such a tip is a pretty good indicator of its
non-practicability.

I totally agree with your statement. Soldering is not rocket science and
is not a new procedure....... why re-invent the wheel, particularly a
time-proven and fairly cheap and readily available wheel.

At work, I used to go out on the wire harness mfg line and dip
standard soldering iron tips in the solder pot. Worked great.

Liquid flux always was helpful too, but very messy stuff.

Now come on John would you buy a soldering iron that had a aluminum tip ????



Give us a break !!!!!
Anybody like to go bankrupt here manufacturing soldering irons with aluminum
tip, even it does soldering great !!!

No. That was kind of my point, if you'd re-read.

The point is, they *don't* "do soldering great," hence they are not being
made.
