Solder like glue ?

[JR]

That means solder which likes glue. When i squeeze the "solder glue"
on the joint, it will be dried in few seconds and the components are
fixed on the motherboard. Of course the "solder glue" is conductive.

Does this products exist ?

So that users do not need solder iron again and save one hand

I think it's quite useful and convenient, especially for electronics
beginners / students.

Thanks very much for answer.

Solder Glue = Cold Joint ;-)

it's your opinion.

No. It's _experience_.

There are conductive glues out there, if that's what you mean. If they
were comparable with solder in performance I think folk would be using
them instead of sweating over lead-free solders.

Bison Electro kit. Contains silver particles. Very expensive.
Never tried it.

When I studied electronics 20+ years ago, we were taught that a solder
connection actually made a chemical bond between the two metallic
surfaces, that it was comparable/similar to a melting and combining of
the two metals, there was actually a change at the atomic level.
Airplane/model glue used to do that to plastic, at least when I was a
kid. A good solder glue would have to be able to do that, I'd think.

Top-post _and_ use the sig delimiter to suppress the _whole_ post that
you're following up to?

What a waste of bandwidth you are.

 

[Brian]

Again, same experience here. Cold joint. Solder bonds on a much more
efficient level than glue.

That being said, it does exist. In those circuit fixing pens. Lose a pad,
use some of that stuff in a non-critical app.

Does it have to solder? How bout silver epoxy. Used it to bond down
filters that needed good ground connection in shaky eviroments.

OOPpps! I meant to sign this as me! Sorry for the confusion. New spoof ID,
and all that.
Thanks,

I think "chemical bond" is a little extreme here. About the only
similarity it has to welding is that if it's done right it leaves a nice
shiny fillet. Well, there's hot molten metal involved. But with soldering,
the parent metal doesn't melt, just the solder. What makes the bond better
than glue is the way it _wets_ the metal of the joint. But they don't make
new compounds or anything, they just stick way better than glue. And, of
course, the metal-metal-metal joint is the only one I'd really trust to
stay conductive. In other words, don't glue your parts to the board.

Cheers!

Not quite correct.
There is some alloying of the copper wire and the solder.
In fact, there is an alloy of Ersin Multicore that is called SAVBIT
that has some copper in the alloy, so to protect copper tips ("bits" in
England) from being "eaten" away.

Remember the Tektronix tube scopes? They used silver-on-ceramic terminal
strips, that required a special solder because if you used "normal"
tin/lead solder it would leach silver from the terminal strip somehow. The Tek
scopes had little spools of silver-bearing solder inside that was appropriate
for repairs.

Yes, the metal of the terminal definitely does dissolve in the solder, to
a certain degree - this is also why tips erode. I was only nitpicking
about whether this dissolving action could really be called a "chemical
reaction," which they taught me would result in new compounds, not just a
new alloy.

And, if somebody were to come up with some kind of glue that purports to
make as good of an electrical connection as solid metal, I still wouldn't
buy the stuff, because they're blowing smoke up my ferndock.

Yes. But it won't "be dried in few seconds".

...Jim Thompson

You could probably get it sufficiently cured(but not fully cured) faster by
putting the workpiece in a warm enclosure,box with a Xmas lamp string
inside.
Here in sunny Florida,I just put it out in my car,gets to 140 deg in there
on many days.

Ah,yes,the good ol' days...
Nowdays,you can't even get TEK to include real schematics in their "service
manuals".


And those ceramic strips were very handy in creating test load for
switchers or for cal fixtures.Hot glue them down to a old CRT filter or the
bottom of a metal box,and you're ready to assemble.I hated it when they
were deleted from bench stock.

Exactly the same problem.
The ceramic strrips had silver plated fillets for the components, and
standard solder would leach away the silver, due to the alloying i
mentioned.
Using a silver-bearing solder (3% silver, if i remember corretly)
prevented leaching, as the solder was already a eutectic (chemically
"balanced" alloy).

Solder forms a compound called an amalgam, where the copper of the wire is
dissolved by the lead in the solder. The old model airplane glue was
mostly tolulene, which dissolved the pieces of plastic, then evaporated.
Neither causes a change at the atomic level.
