i'v done that, but insulated wire has more possilbilty's for routing - if it's not going to disolve on the soldering tip!!

With a stereo microscope and decent tweezers it's possible to do crazy routing with non insulating.
I have some of that chineae wire and my issue has not been the wire melts but I seem to have an issue getting the coating off.

Now there's a problem I didn't initially think of: the wire itself melting. I DID work with enamel copper wire before to run jumpers for destroyed pads on micro USB connectors on phones and tablets at my old shop, but not this thin and I agree: getting it to tin properly was a chore. I tried different methods over the years like taking a razor blade to it and gently scraping or taking a flame to it, but none produced satisfactory results. The blade method almost worked, but it often left behind uneven results, since the wire is round and the blade is flat, so getting ALL the coating off was impossible. The flame got the whole coating off in one go, but of course charred the wire which made tinning difficult, again, resulting in uneven coverage...the chaps over on Ali claim the coating comes off with just the iron, so fingers crossed it works

I found a small bobbin of 0.1mm wire this morning that has a bronze colour coating similar to your link.
I can't see the coating meting away but i am able to solder the end and then bend the wire and solder and melt the coating at the same time on the next pad. Even at 500c there is no meting of the wire but then it's 10 times thicker than 0.01mm, that's insanely thin.
Possibly a bit to thin IMO for laptop trace repair.

Louis uses 0.08mm wire, so as I was searching for that exact size on Ali, those 0.01mm and 0.02mm spools popped out and I just went for it thinking thinner is better, not to mention they were very cheap. Like you said, I have NO idea how this is going to work as that is indeed microscopically thin...we're talking 10 friggin' microns here (20 if I use the "thicker" one) ! I'm not even sure I'll be able to SEE it, let alone solder it

I got the 0.01 and 0.02 as well, so fingers crossed I don't drop the spool off the desk and it turns into a hairball

Talking Re: Soldering station thoughts and guidelines

This showed up in the mail today. The photo doesn't really do it justice, so here's the product page to see for yourself. It took me a while to find this, since it's as close as you're going to get to a MicroPencil. It still uses the T12 standard and I stumbled upon it mostly by accident among the ubiquitous T12 tips. Haven't tried it out yet.

I still don't understand the use for those ultra-thin tips. Aside from soldering very fine-pitched resistors and TSOP/TSSOP ICs, I'd hardly ever fine use for such tips. Even if fixing thin traces, I still use my fat D52, lol.

As for thin wire for trace repair: I just pull strands from various regular wires. If I want something very thin, I use the wires out of audio cables. Those tend to have very fine stuff in there.

the function of small tips is not to solder fine parts, it's to avoid other stuff nearby.

That's a bit barbaric You must have an amazing hand then, like those guys balancing eggs and opening bottles with bulldozers

I tried that, but the thinnest cable I had (not audio, indeed) had strands that were still too thick, so I turned to that extra thin stuff on Ali. A couple of days ago, mostly out of curiosity, I ripped open a cellphone buzzer which was dead anyway and its coil wire was more like what I would attempt to fix those traces with. I also tried tinning it and luckily it tinned like I expected, with a little bit of persuasion. I didn't save it though because my spools are on the way.

Eh. Yes and no.
I have terrible coordination when it comes to sports.
But for soldering and doing precise work, I have fairly steady hand. It's really the long nails that help me do the fine work. Tweezers work for certain stuff. But when I want to solder 0812 SMD parts, I simply place it where I want with the tweezers, then use a finger nail to press on the part down on the PCB, then touch it on one side with a sharp (but not thin!) soldering iron tip... then on the other... and done. Same with soldering wires to fine traces.
Not using microscope or magnifying lens either... though now that I've made it to the 30 YO bandwagon, my eyesight for close range is starting to feel a little awkward compared to 5 years ago.

Pfffftt, yeah I've never been into sports to begin with, so if I were to try and pick one up now, it'd probably be golf or air hockey or something
However, I feel you: I suck at what I call "motor skills" and by that I mean stuff which others seem to do perfectly, but I can't, like juggle, walk on their hands or doing backflips...

Ditto, though it's starting to deteriorate, as I've been doing less and less of it lately and more and more "physical" work instead, like running wires, stripping them and installing alarm systems which seems to have become this joint's main focus ATM, to the point where it's sending us techs out of the shop to do it due to never enough employees to keep up with the enormous amount of sites they took up

I don't have much choice in that matter, because I don't have a microscope anyway. I do use an assortment of magnifiers, from handheld ones, to a larger LED one with an articulating arm mount. Sometimes it's just NOT enough and I crave for a microscope....
