Theoretically yes, but it's harder to control the heat for the duration you need to do that. The flex substrate is pretty melty. I would try it with a shovel tip and a whole lot of spares to get the technique down, but if I only had one shot, I think I'd go with the author's technique, one wire at a time. Perhaps with less gap between the ends, though.

I’ve done this many times and in smaller ribbons with narrower traces, this is a FPCB the substrate is kapton and it should whitstand soldering temps pretty well the trickiest ones are FFCs (the white ones)

  Oh good call, yes most of my experience is with the white ones. Clearly I need to tinker more! :)

  Ah. Good to know. I actually attempted something like that before this particular fix and it didn't go well. Hence I "gave up" and did it the "hard" way by hand.

The gap was to make up for the amount of ribbon I'd damaged along the way. I didn't want to shorten it too much!
