Torn screen flex fixed successfully Just a fun Soldering Post =)
This is my first attempt ever to fix torn display and touch flex, and it was successful! Does not look best but I am glad it works. Only soldering mask is missing, should arrive tomorrow.

I do similar stuff and my response to that statement is that a lot of people would die if I were one. With electronics you can usually just throw them in a corner for the week and wait until you feel like fixing them. With people - not so much.

Nice work at moment. But you should understand this ribbon was broken in bending point. Could you bend it here after you soldering? Does it work after bending? P.S. Neurosurgical work anyway!

Okay now just don't breathe in its direction before the solder mask arrives!

Can you provide some details about your techniques?

Firstly you need to scrape traces, where the wire will be soldered. TIP - Scrape the traces not next to each other (in a zig-zag pattern), its easier to solder wires in a row like that. After that good cleanup is important, best with some isopropyl alcohol. After that I used flux (a lot of flux) and got the solder on scraped traces - I tried also without it, but it was not working so great. I took the thin wire and started soldering - soldered top first, then bottom and after that I cut it with a sharp knife right next to the bottom solder point. I did it with a simple magnifier, but if you have a digital microscope, it's much easier, because you are not so close to the soldering area and your neck is not in pain. I think I am going to order a digital microscope immediately 😀

I'm honestly having a hard time believing that worked.. but if it did then you did an amazing freaky job! 👏

how long did it take?

Like 4-5 hours. But only because I don't have any sort of microscope, only a simple magnifier on one eye. It would be faster if I had it.

Amazing works! I would love to be able to do that one day. Man it would've saved my ass couple times if i acquired this skill in the past

Impressive! Did you apply UV ink over them and insulate it?

Damn. That didn’t look easy. I might have tried this 20 years ago. I don’t think I have the steady hand and eyesight to do it now.

This is wizardry. Seriously nice work. I have to know though... How many obscenities did it take to get this fixed and working? My count would have been in the dozens if I could do it at all 😂

Had to do this recently as well for a tiny flex cable. Luckily only one line was actually damaged, the two next to it were mangled but working. (Accidentally sent a screw through the ribbon cable assembling something)
I can’t imagine doing it without my microscope though and a very sharp x-acto blade and flux are your friend. Then I used UV curing resin over the fix and a piece of packing tape across that section to keep it from bending.
