Crimping Help
« on: 30 Mar 2015, 03:26 pm »
Hi Everyone

What crimp tools do you recommend? I am trying to crimp to avoid soldering, but its proving to be a bad idea...

I can't find a tool which can do the really small size for Neutrik xlr crimps:

(which are said to need this die)

Any ideas

Since you're only doing a very small amount I'd highly recommend just soldering.

I thought crimping provided a superior connection, though?

It can but for this application it's fine.  For an XLR connector inside the chassis I wouldn't worry about it.  For airplanes, race cars and other high vibration applications crimping is far superior...

OK. I will revert back to the soldering idea. Now have to order some other iec and XLR inlets again!

I wish someone make XLR like Neutriks speakeron chassis. They are great, you just stick the wire in and screw....

Electrically speaking, only a "perfect" crimp will provide a better connection than a good solder job.  A "perfect" crimp can really only be achieved with a hydraulic press, any other crimp connection, made with a hand crimping tool, will have voids and not be gas free, allowing for corrosion over time of copper wires, and also additional noise.
For sonic performance, soldering is going to be better, or crimp, then solder to make the joint gas free.

...or crimp, then solder...
This is what I did when I recently made a few short runs of speaker cables terminated with spades. I didn't trust my hand crimping tool to get a gas tight connection.

I just came across this Power Point:
