this works for me…$0.02usd

edit: haha, @BluPenguin beating me to the punch!

  1. heat-sink the braid on either side of where you want the solder. the idea here is to keep those parts cool so the solder stays in a thin transverse strip and keep it from wicking and ruining the flex.
  2. wet out the braid along the strip you just made.
  3. cut the braid along the solder line. this should result in two nice clean edges. you can also check for how well you wetted the braid with solder.
  4. repeat as required to get the strips you need. I solder all cut edges of the braid.
  5. prepare to solder the strip to your nickel. Heat-sink the strip again to keep the solder down near the solder joint.
  6. run a bead of solder along the edge of the braid to form a nice fillet on the nickel.

should be a solid solder joint but still flexy
this works to solder braid to PCB’s as well
