Hi, Thanks for posting with pictures. I have broken flex cable of the LED bulbs behind the LCD of Macbook air. I have to make 6 solders. The cable is broken in to two ( Apple refused to sell it, I must get it done by them costs 125€).
I have a microscope and a 0.2 tip on my 12w iron. I will give it a try tomorrow.

Sorry for necroing, but that guide was amazing!

I wonder, can you reduce (or even remove) the soldering risk by instead using a hot air gun along with some soldering paste? That should allow even those of us with unstable hands to do this (if we manage to scrape it without re-tearing it).

Hello everybody,

Thank you so much for this post. It certainly gave me a lot of ideas on how to repair my flex cable.

(Sorry for the out of focus)
I accidentally cut the LCD ribbon cable on my ZTE v875 Android phone while disassembling. The cut crossed 5 tracks in the flex cable.

This is my amateur workbench. Notice the double magnifying glass contraption to increase the zoom factor! After this I'm certainly going to buy a proper magnifying glass.

Each of the tracks in the flex cable is around 0.3mm wide. I removed thin wire from headphone plugs (around 0.2mm wide) and used it as jumper wire to connect the broken tracks. The soldering iron tip is 2mm wide!!!! Needless to say, this was a huge pain in the *** to solder. I found that using Cyanoacrylate Glue (Super Glue), is very handy to hold the wires into place (I used a fumes mask), it also melts again into liquid when heated with the soldering iron, which allows repositioning the wires.
I tested the tracks for continuity and short-circuits. It certainly looks ugly but the phone is working again

Default CD63ki ribbon connector

Wish I read this before I tried to repair breaks in a 20624 ribbon connector from Marantz CD63KI!

Impressive example of a diy repair!

Hi, Yesterday I finally managed to repair the flex cable in my camcorder that had me stuck for months. I made a video to show how it was done and thought this may be useful to others with the same problem. It's on youtube here:
