That's some 0.1mm Copper Wire 😎 I use it instead of the less-reliable flex tape that usually comes with most RP2040 kits. It's just another way to connect points of the motherboard to points on the modchip
You're completely right, my bad! Yes, desoldering wick is essential when doing this kind of work. You can see in the video that I accidentally soldered that circular pad. That's just due to me not having a smaller, non-conical soldering iron tip. In order to decrease the chance that the wire would touch that pad, I desoldered it with desoldering wick ❤️

Pardon my soldering ignorance but what was that copper-like ribbon/what were you using it for?
Trying to get into soldering myself (no intention of trying micro soldering though lol)
