Not hardly. Cat crimps and solders wire terminations, as you
mentioned, on circuit boards, as well in as but splices, ring
terminals and similar, military connectors, ITT Cannon (Sure Seal)
connectors and a few others.
They only crimp terminations in all Deutsch connectors and some other
lesser used connectors.
Due to the quantity of wires in the Deutsch connectors versus all the
other terminations approx. 60% are crimped only and 40% are crimped

Again, depends on the application. I jes replaced all the battery
cables on my 6V golf cart. Severe corrosion where the stranded heavy
gage cables crimp into the battery lugs necessitated it. The new
one's are the same thing, so will probably encounter the same problem
eventually. I suspect this construction is more about economy than
effectiveness. Why waste money on solder when crimp will do, in the
short term. I helped one lady with a bad golf cart cable. She was
trying to crimp on a new lug, but had no proper crimper. I soldered
I had a roll of solder and Bernz torch back at the house. Fresh outta
anti-corrosion spray. Besides, the real problem was lack of crimpers.
All she had was a pair of channel locks. I also didn't have a crimper
large enough. The solder worked fine.
You are suggesting that soldering, although more time consuming and
expensive, would be better for longer-life applications.
Back in the early 60s, I worked with an engineer that needed to
determine which type of connection would be best for use in a
high-reliability military system.
Half of several connector sets were soldered, half were crimped. This
included using smaller gauge wire in some pins, folding the wire for
My job was to monitor the testing, which included vibration, shock,
temperature cycling, humidity cycling and salt spray.
As I recall, there were numerous failures of the soldered connections.
The only crimp failures were where smaller gauge wire was used.
I said "depending on what's needed". I made no claim that soldering
was always better nor that crimping was always better, only that
crimping is faster and IF conditions are such that crimping will last
the design life it's likely that manufacturers will crimp rather then
solder. Same as why production electricians will shove the wires into
the spring clip holes on home electrical outlets instead of taking the
time to wrap the wire dinner the screw and tighten it. Same reason
many things are pop-riveted instead of brazed, and on and on.

Despite the agreement from posters in general, line by line, the url
reads like a satire to me.
20 years ago I bought a selection of crimp connectors from J.C Whitney
on sale for about 8 dollars. Maybe 18 different kinds and sizes
totally 200 connectors For 8 dollars. 4 cents a piece.
Came with a crimping tool, which I use,
Am I to believe that the quality of the connectors is sufficient to
make a crimp? With cheap connectors, soldering sounds better to
The key word in "proper crimp" is "proper". If you can't guarantee
that, solder is good but it will cause other problems. If you're
worried about the connection (or if a fault may cause damage or the
possible loss of life), dump the crappy connectors and crimper and do
As I may have mentioned I just retired from Enersys-Delaware which is a
major manufacturer of industrial batteries and I was in close contact
with the engineers at Anderson as we used their connectors exclusively.
Crimping is preferred to soldering.
Just make sure you get a good crimp. Most of their contacts require two
Soldering is acceptable but you must absolutely insure you do not splash
any solder on the mating portion of the contacts. Since the contact are
silver plated, solder will degrade the connection.
