Kinda hard to crimp to a circuit board or ceramic strip, isn't it, Jim?
Don't remember ever seeing a crimp in my 30 + years at Tektronix. Guess
TEK had it right...for them, anyway.

Au contraire!
Ceramic strips (which were only used in 'legacy products' when I got
hired in 1968) used solder (2% silver)
Circuit board components were either hand or flow soldered with tin/lead
solder
But the board interconnects (nicknamed 'harmonica connectors') were all
crimped, not soldered.
Ah, those were the 'good old days' :)
Stu
And when I got hired, even though I thought myself a pretty fair hand at
soldering, I spent a week on the production line learning how to solder
the Tek way. Ayup!

Yep, that's me...Legacy products
500 series scopes & plug-ins till my left arm went to heck from tweaking
vertical plug-ins. then ckt boards for a while, then the lay-offs
started.

Hey Ron. A vehicle running down the road will see a lot more abuse than a test instrument. Most of what I've read about soldered joints in vehicles speak to the solder creating a hard transition to an inflexible connection and with vibration the wire eventually gets work hardened and breaks.
I experienced a different type of soldered connection failure. I was chasing an intermittent non-start situation that had no rhyme or reason, might go months without the problem showing up. Finally happened when I went to start after filling up. Opened the front hatch and the battery cable end was no longer in contact with the terminal lug, and it had been a soldered connection.
I think the connection was borderline so it sometimes wouldn't start, then the resistance would heat up the solder enough for it to flow and improve the connection temporarily. Over time the cable worked its way out of the terminal lug.

I used to be a solder guy, and was continually chastised by an ex army A+P chopper guy who said crimp was the standard. I had too many crimp fail to convert; that is until I got a new crimping tool. I use a Southwire crimp/strip tool and it made all the difference in the world. Now use crimp and heat shrink ends and have zero failures.

Richard,
That has become common these days and it is not the result of solder directly. What used to happen is the stranded cable was "pot tinned" where the end of the cable was dipped for a given time in a solder pot. This was then sent off to have the lead connector molded on to it. When this was done correctly and with both alloys correct, it was a very capable and durable part.
Unfortunately, with the OSHA and EPA all over lead operations (a well deserved situation), all of that got moved. First it went to Mexico and now Pacific Rim.
The high tin alloy that tins copper best is expensive and has not been continued. The alloy for the post clamp has also been changed and this means a lower temperature for the clamp molding and that means less bonding of the cable to the clamp. I have several times seen this so bad that the cable could be removed from the clamp with little effort. (This does make for a puzzling "No Crank".)

I use to believe all connections should be soldered till couple of times
the wire fatigued next to it as the rigid solder contributed to flexing
right next to it and fatigued and broke and had heck of a time finding the
issue.
A good crimp is only as good as weather seal outside area.
There are lot of heat shrink seals to use.

ANY crimp connection made with one of those stamped steel stripper/crimper is a joke and will fail very soon.

I’ve been using a Sta-Kon crimping tool for a while, including their terminals.
The tool makes a three part crimp that is utterly reliable.
I’m sticking with their terminals, too. They are more money. Worth it, too.

Sta-kon is a very reliable supplier. Note that the lug material gets thicker as the lug size change from Red to Blue to Yellow.
3M is also a very good supplier.

Hi all,
Having been in the repair, replacement and design of wiring of control
system for 40+ years I thought I might get in with my 2 cents on crimping
VS soldering, crimping mostly!
First lets talk about crimping tools. The first pic shows a series of
combo tools that crimp poorly, strip wire marginally and actually can be
used to shorten small bolts and machine screws.
http://www.gmcmhphotos.com/photos/general-pictures/p61255-crimping-tools.html
The next group of pics shows a crimper from Harbor Freight that works
really well.
http://www.gmcmhphotos.com/photos/general-pictures/p61250-crimping-tools.html
http://www.gmcmhphotos.com/photos/general-pictures/p61251-crimping-tools.html
https://www.harborfreight.com/ratcheting-crimping-tool-63708.html
And for HD wire crimping I have used this and I have found it ideal on 8 ga
and larger wires.
https://www.harborfreight.com/hydraulic-wire-crimping-tool-66150.html
For general and all purpose crimping I have used the following Thomas-Betts
for decades and it is absolutly the best.
http://www.gmcmhphotos.com/photos/general-pictures/p61248-crimping-tools.html
http://www.gmcmhphotos.com/photos/general-pictures/p61249-crimping-tools.html
This is a crimper sold bay HF that is just OK!
https://www.harborfreight.com/9-12-in-wire-crimping-tool-63989.html
Lets talk wire strippers. I have used this one for many years.
http://www.gmcmhphotos.com/photos/general-pictures/p61252-crimping-tools.html
http://www.gmcmhphotos.com/photos/general-pictures/p61253-crimping-tools.html
Here is on that is sold by HF that also works.
https://www.harborfreight.com/heavy-duty-wire-stripper-and-cutter-56266.html
For smaller wires 16 thru 22 ga i like this Thomas-Betts auto stripper, but
it is too expensive if your not doing a fair amount of wiring.
http://www.gmcmhphotos.com/photos/general-pictures/p61260-crimping-tools.html
http://www.gmcmhphotos.com/photos/general-pictures/p61261-crimping-tools.html
http://www.gmcmhphotos.com/photos/general-pictures/p61262-crimping-tools.html
I also have a wire striping knife which has a reverse point in the end of
the blade and is not overly sharp. It is a safety blade and it locks open.
http://www.gmcmhphotos.com/photos/general-pictures/p61254-crimping-tools.html
So in the end this is what use.
http://www.gmcmhphotos.com/photos/general-pictures/p61247-crimping-tools.html
I have done the soldering of wires too and find it does have a place in
wire terminations. Wiring to circuit and circuit board repair. Circuit
board in the 60's were mostly hand soldered. Soldering can be difficult is
your just an occasional solder user. When I went thru USAF electronics
tech school in 1967 we had a week of how to solder correctly. As we say
with most things practice makes perfect.

So for my morning reading with my coffee I googled "crimping vs soldering wire terminals" to see if I could find some hard info on this.
The top search result was from Monroe Engineering LLC Inc.
https://monroeengineering.com/blog/crimping-vs-soldering-cable-connectors-which-is-best/
Third paragraph reads (after describing crimping):
"What Is Soldering?
Soldering, on the other hand, is a process that involves joining two or more objects using heated metal known as solder. Unlike with welding, the objects -- which in this case is a cable and a connector -- is not heated. Rather, soldering only heats up the filler metal. As the filler metal, the solder, heats up, it's applied between the wire and the connector. Once it cools, the solder hardens, thus joining the cable to the connector."
For the last 50 some years I've been heating the parts to be soldered and thought I was pretty good at soldering... now I find out I've been doing it wrong! (sarcasm alert)
This company makes wiring harnesses and cable assemblies so I hope they only crimp.
But again, I'm not an Engineer so I could be all wrong.
BTW, When I was doing a higher current connection, I would crimp the connection as normal, but also solder were the end of the wire came through the terminal. I figured this gave me a seal to the exposed strands but also did not have the solder wicking up the wire strands causing the strain relief issues. JWID.

Yes it is. Are you recommending using synthetic or dino core solder? What weight?

I was told to heat the objects to be soldered enough to melt the solder,
which would then flow between the objects to join them. Remove heat, let
the junction cool a bit, then on to the next. Never heat the solder and
let it flow onto the objects.

Yep, that's the TEK way for sure. 70/30 Eutectic solder only. EVERYTHING
SCRUPULOUSLY CLEANED. RESIN CORE or solid, but using resin flux on every
joint. SOLDERING IRONS SHARPENED AND PROPERLY TINNED. ALWAYS, ALWAYS
meticulously cleaned up with alcohol, post soldering. All loose ends short
clipped. It better look good, as well as be electrically and mechanically
sound. Been there, done that, still do.

70/30 is NOT eutectic. Eutectic (lowest melting point alloy) is 63/37 and is what I use as it heats the device and flows the solder fastest.

Johnny,
You apparently did NOT READ the caption under the picture. Suggest that
you go back and read the caption under the picture! Scroll down just a
little bit and you might be surprised. Sometimes extra information is
available in the captions such as model numbers, explainations and part
numbers.
