Aerotronics "Solder a shielded wire"

This video is intended for instructional purposes. Here Jeff Matye of Aerotronics demonstrates the method for connecting a wire to the shielded portion of a twisted pair of Tefzel wire. This is used to provide a conductor to the shield for termination.

Love the technique of pulling the wires out through the shield. Thanks for that!!

Jeff...nice job on your video. Nice, crisp, video. I appreciate your excellent use of the black background to focus/highlight the overall process. Well done!

Nice video. I do prefer to leave the shield intact around the conductors, though. Then you simply solder another lead around the shield like a ring and heat shrink all of that. Keeps the shield intact right up to the end of the conductors instead of leaving 6 inches bare. The shield is there to block noise after all. Stripping it away sort of defeats the purpose. Also soldering a separate lead around the shield instead of "tacking" the ground connection is much stronger.

Your solder-fu is impressive. This was super useful!

“Solder-fu…” Hahaha, good one!

I envy your precise and steady hands. You are an artisan with the pencil iron ♠️

Great instruction, thanks! I'm well acquainted with solder sleeves, and a couple different techniques for using them; however, there's room for error if they aren't used correctly. The technique you demonstrated leaves little room for error and likely results in a more streamlined harness when numerous pigtails are added to a connector.

Thanks for posting as I'm making new p leads for my 0-200

Wow. Serious virtuosity.

what is "an inch" ?

Navy trained Avionics tech here, worked on everything from MD80s to C130s, 767, 757, 737, on and on. I have never used, or would be allowed to use, a solder joint like this. Any shielded wire would get the ground wire with at least 1 /4" join. That is way too short on the ground strip back, and is probably a brittle joint since you are moving it as it solidifies, don't care how carefully you are trying not to move it. And modern solder splices completely make this an outdated.

Remember, solder is an electrical connection, not a mechanical. Also, Isodyne backshells replace solder sleeves now.

[@LTVoyager]

@@Crunk99ify Who told you that? Solder is both electrical and mechanical. What do you think holds PCB components in place?

[@foesfly3047]

I thought the same thing about the creation of a brittle joint in the soldered shield. If I used this method, I’d be extra careful to leave a significant portion of the twisted shield/braid unsoldered. I would also add a second layer of heat shrink over this section to add support (add some resistance to flex) to the joint. But we aircraft maintainers can certainly obsess over which hairs to split.
