Homemade Solder Wick/braid

I wanted to share with you this trick i learned years ago when i was trying to clean some Pcb traces. One night while i was doing some electronics repair i found out that i run out of solder wick, because i don't use it that much i didn't care to have extra of it, so i grabbed a piece of copper wire, i smeared it with some flux and i use it as a solder wick and it worked like a charm.

Step 1: The Making

To make your own solder wick you will just need a piece of stranded copper wire and some flux.

  1. Strip the wire
  2. Twist the wire to hold a straight shape
  3. Apply some flux to it

And now you just made a solder wick from a piece of copper wire, you can use it as the usual solder wick.

    Shazam! We got us some solder wick. I tried this a month ago with coax shield, but didn't use any flux. Solder draws towards the heat, and shield is woven much like wick, so it seemed feasible. No go. The stubborn little wad didn't even melt, but I think I heard it snicker. It's been a while since I had the Weller out, and I totally fogged on flux. I just tried your method with flux, and what a difference. Works just like the stuff that comes in those overpriced plastic yo-yos. I have about a third of a 500 foot spool of plenum coax and a tin of plumber's flux. I might be set for life. Thanks, amgworkshop.

    Tried this now and wondered why it didn't work without flux and then I read your comment. Good info about the acid stuff too. Guess I will head out tomorrow and pick up some electrical flux.

    I learned a few months ago that plumber's flux is not suitable for electronics soldering. It has an acid component that will eat soldering iron tips and is corrosive on solder joints if not COMPLETELY washed off. I learned about soldering tips the hard way when a brand new one started corroding and wouldn't stay tinned, just like the one it replaced. Found out in time to save it though. So, a little knowledge for those who don't already know, use only electronics grade flux on your projects. A big can of Oatey may seem cheaper, but is much more costly in the long run.

    But the shield on coax video cable still makes great solder wick, especially the plenum stuff. The teflon casing doesn't melt and burn if you're using it as a handle. But it can get pretty hot. I need to come up with a better handle.

    and use the wires for traces on a circuit board....
