You get so 'blind' just seeing the microscope version, then you show the actual version and its repair and realize just how absolutely tiny it is. Well done man.

[@jmigserra1986]

Exactly! I missed the part in the beginning when Alex showed it, and I wasn't expecting it to be so tiny when he showed it at the end of the video!

[@dirzz]

Anyone who attempted such microscopic repairs, especially on a material that is so fragile and susceptible to excess heat knows that it's insanely hard to do what Alex did here even with all the right tools, BIG respect!

[@gillsejusbates6938]

for real! Very skillful, if it was me doing this job, i would probably have to resort to soldering enameled wire directly to the headers that this cable is supposed to connect

[@faghihimohammad]

It's like performing neuro surgery on electronic devices!

[@3ijnweu3oq3]

Trust me, I done a similar thing. When you have a microscope its so mich easier to do.

[@dirzz]

@@3ijnweu3oq3 it's damn near impossible without one. I've done it too, that;s why I'm saying this.

[@KimoKimochii]

i’ve been trying to do this for the past 6 months, it’s way harder than it looks here, you spend too much time soldering on the area the coating of the flex and the flux gums up and ruins everything. Everytime the soldering iron touches the part it has to do something useful otherwise there’s not that many chances left, also soldering one wire without touching the one next to it is super hard, and many people don’t realize, holding the wire with the tweezers is an art itself, the wire has to be at the perfect spot on the tweezer tip, too high it won’t touch the solder, too low you may lose the grip on it. the wire itself also needs to be at the perfect angle and oritentation. omg i didn’t know it was so hard until i tried it myself, right now i can only do 2-3 out of 10 traces before everythjng melts and gets ruined lol

[@3vil682]

I never thought that broken flex cables could still be salvaged... wow, my respect.

[@BahhBahhBrownSheep]

you must be new here

[@vitor900000]

Some can not. It depends on the quality of the plastic. They will melt and shrink in the heat of the iron.

[@Zbucket]

graphite ones are tad more difficult but ofc it all depends on the quality the flex is made.

[@jakapratama2590]

Normally people don't bother to fix the broken flat/ribbon cable, just replacing it will save a lot of time and effort should a replacement part is available, and mostly it's not that expensive. Possibly this cable do not have a suitable replacement ready, or it is too urgent to wait for replacement part comes, or both.

[@3vil682]

@@BahhBahhBrownSheep I've only known this KZbin channel for about a month, and I've already learned so much from it. It really improved the way I work on my personal projects. So, yeah, you could say I'm relatively new here, haha

[@dominicm2175]

When Alex got burned out as a Neurosurgeon and wondered what would he do next, his wife told him he’d do very well repairing ribbon cables 🤣

[@zelikcosio-altamirano6453]

Hahaha, that probably did happens as he has the steady hands of a Neurosurgeon!

[@spacedmanspiff1543]

That's where my thought process went as well...lol. well done NF !

[@fayyazkhattak4726]

One of the finest jobs I've ever seen. You're a gem mate! ✌🏻

[@DanielMolina1982]

This has to be the most precise thing done by hand I've seen in my whole live. I do some microsoldering myself, but this is not from this world. Hats off!

[@3mariusx]

True

[@louf7178]

I did a similar attempt of this bridging with much more crude tools on PCB (traces got eroded and I wanted to bridge them). It was very difficult; the heat would often move the previous wires. I eventually did get most traces bridged. I can see similar techniques, and those are the best for control and placement. I also had to develop a technique to keep the hand steady - the slightest movements are big at this level. Excellent work! I wanted to make a soldering laser to alleviate the motion problem. I think it should work, but I never got to making one.

[@RutgerJGroen]

Incredible work, Alex! Could you keep us updated if the client was able to make the flex-cable work, please? 😊

[@alltechrepairs1495]

Lovely job Alex. The echo's of my screams are still in the air months after I tried to repair a ribbon with only 5 wires. Tacking one lifts two that are completed. Ahh!

[@tuntona5133]

I am glad you did not send any UV light through to us Alex 😉 Amazing job !

[@alantorrance6153]

What an incredibly "fiddly" fine job. Congratulations.

[@marcs9068]

Thank you for not blinding us with the UV light. :)

[@ashleybignell2366]

excellent repair. Looks the prototype cable will be getting a revamp before its final installation.

[@kensgold]

I do micro soldering as a full time job for a company that designs ic's. Let me just say your repairs of the pads, and traces under gpu footprint, as well as this flex cable showcase an incredible level of precision. Thanks for sharing your expertise. I have always replaced torn flex cables, I might have to give some of the broken displays at the office a whirl.

[@BigNiqEnergy]

Big Salute and a true display of skill. I salute you o7

[@rittol2365]

Jeez can't image the panic when that ribbon ripped the day before a presentation

[@donaldokpara286]

You are the Man Alex

[@shank3111]

it would be good idea to test the connectivity before applying mask. Anyway great job indeed. Keep it up

[@x-fix]

Very well done! From my own experience I can tell how difficult it is to work on these type of cables.... Fantastic result!

[@TallyTechandTroubleshooting]

Pretty amazing, Alex. Fantastic job!

[@jonas0937]

You ve got surgeon hands. Very steady and precise. I'm jealous of it, as health issues left me with shaky hands. It can be overcome with tricks to microsolder properly, but no tricks can replace steady hands. Thank you for your amazing content. Learning a lot here. Cheers from France

[@nickolaswilcox425]

ive come into possession of a prototype device with a similar sort of damage on one of the custom cables and am debating sending it in for repair.

[@dinkc64]

Master at work.

[@achilledepoitiers4462]

VERY impressive work! I fixed one flex cable myself by splitting, lengthening, separating, and rerouting the individual wires, it was quite nerve wracking, and that was only 4 wires with far more space, after practicing, using an inverted prime lens as a magnifying glass. Again, VERY impressive work, and VERY steady hands. I see that 'I did it' grin; well done!

[@MJPilote]

Oh my, that is insane precision! To be able to solder so tiny traces without making a solder blob out of that tiny flex! Respect!

[@jakapratama2590]

This thing here, this is not something people would want to do as a regular repair service. It's an emergency repair, and it is suggested to replace the part ASAP with replacement part after the emergency comes to pass.

[@TheDanielSpies_Arcades]

Beautiful work, I was shocked how small that flex cable was compared to your finger. 😮 🙌🏻

[@theftking]

This is some legit soldering.

[@JKEYAUTO]

Long time viewer! Did a ribbon cable repair today! Much more basic than this, only a partial tear with only two broken wires but succesful! Thank you for making these great videos!

[@ejeckk]

I could barely watch this. I was stressed out the entire time. When you started scraping the cable with the blade, I was getting woozy. But you pulled it off, Alex! Outstanding work.

[@billg7813]

Better than factory 👍🏻

[@Micharus]

Impressive work. What I want to know is.... did it work? I mean, it probably did, but we didn't get to see the 'prototype' it belongs to working with the cable in it.

[@Arokhantos]

That customer should have spares of that cable for a prototype

[@RestoreTechnique]

Usually when i try this I'm constantly accidentally desoldering the previous wires I've done 😂

[@dilukshajayaruk8553]

You are a genius 🌹

[@lezen106]

Man that’s literally as precise as heart surgery … you probably picked the wrong job 😅😅

If this electronics repair thing doesn't work out for him, he can always be a brain surgeon.

[@Dwedit]

When I saw the solder go on about about 6:00 into the video, I got a tad worried about adjacent lines getting bridged together.

[@Mike-ss1ju]

Man, I've been doing microsoldery repair on the side for a few years now and I love it. Just recently started buying monitors that have vertical dead pixel lines. The problem is always the COF which is nearly impossible to replace because of lack of parts and the way they're attached is with a 1 time use glue with an expensive heat+press machine. The only alternative for a lasting fix is to do this and repair the bad trace. Been impressed with your work so far, but I didn't expect to see you repair a flex cable in a similar way. This is stuff that nobody in America really does and you only see it on the streets of India. Very cool stuff. If I lived in your city I'd quit my apply for a job in a heart beat. Woudln't even have to pay me. Just feed me scraps so I don't pass out.

[@MrSSB51]

Alex, you missed your calling as a neurosurgeon. mad skills

[@Prop-A]

Wow. Your experience and practice really shines through here. Insanely dificult repair. Often technicians will say: it can not be done, you need a new flex cable. Amazing man.

[@wesker89]

holy shit this is the most impressive one i have seen and now it makes me wanna try and fix the ribbon cable for my phone lol

[@pablonunez194]

Undoubtedly a master surgeon. What exercises do you do to have that pulse in your hands?

[@boppernostopper8598]

You seem to be heavily breathing from the chemicals you are inhaling

[@rafflesnh]

"...but of course we need a microscope for this". Yeah, and a very steady hand too! Great fix, Alex. Hope it worked out ok.

[@BrianB14471]

The microscope helps steady the hand. Your brain gets extra precision in its biological feedback loop.

[@oneandonlytyler1]

great work,would it of helped to stagger the solder points,by removing board covering at a diagonal angle

Master of microsoldering😊❤👌 Nice Job

[@hectortd4]

The real question is: Did it worked? I'm interested to know even more since this is a prototype which means probably whatever you was holding there, that was it

[@RectifiedMetals]

Wait Alex, we are not cured. You didn’t expose us to uv light. Oh the madness!

[@mechanoid5739]

Respect for the skill required to do this sort of work. I used to do similar work involved with installing microscopic strain gauges and routing fine wires throughout small components. All this work is done under a microscope. It is harder than it looks. I miss doing this work as once I got "into the zone" I could shut out the world and enter my Zen space where all is peaceful and I forgot all my problems! Sounds nuts but it was the best therapy I had! lol!

[@amrelsharkawy6701]

Amazing .. that's a very unconventional repair .. please update us after customer use it.

[@chateaumedia]

A better way is to scratch ribon cable at different un even locations so that you don't risk a short when soldering, or when it flexes later with customer using it.

[@cockneybrian]

Pure talent right there. Alex even enjoyed that one smile at end Golden

[@TechMDYoutube]

Btw your microscope link is not working. Thank you for the awesome video.

I attempted to do this on an iPhone battery ribbon cable that broke on me. I completely failed. I mostly just couldn't get the wires to stay in place. It was so painful! And that was just I think 6 wires compared to the amount here. Insane accuracy!

[@BipolarShango]

I would hate to do this😢 looks so tedious

[@chox2001]

How can a prototype be produced without at least one replacement flex cable. That is bad planning or bad funding. I hope you pull the developers out of trouble and a learning curve starts from this day on

[@RK_MOBILE_REPAIR]

it would be good if you wrap a some kind of tape around the joint to give the flex cable some extra protection and strength

[@TermitesRGood1]

The Flex Cable is a flawed design if it fails in a Prototype Think about the mass market production ... hope it fails this project so consumers have be spared.......

[@DaftdogUK]

Surely if you're building a prototype you'd either A: use off-the-shelf ribbons and order a few of them because they're cheap, or B: use custom ribbons and order a few of them. Setup costs are usually high, materials cheap. So you could have 1 cable for maybe $100, and every one ordered at the same time costs an extra $5. Not having a spare ribbon or two or three to hand sounds like excessive bean-counting or poor engineering. Excellent work repairing it though.

[@mohamedlanjri]

Let me know when you start doing surgery!!!! Incredible pulse, I guess you will pass the truth machine with no problems, your pulse won't fail. I'm thinking to give you a chip to do the wire bonding so I can save costs on the bonding machine. 🤣Great video, congrats.

Hey manufacturers and engineers... Don't glue your batteries or your flex cables! Don't do it. Just don't.

[@abuahmed210]

[@AlexanderSauerPlaysWithHeroJr]

cool. that knive tip is awesome..right now i feel like soldering has become a chore.. like trying to draw a portrait using a crayon the size of a baseball bat 😄 on a piece of paper the size of a business card..🤪 time to invest i awesome xmas gifts to myself. 🤗...

[@LM-bc7pf]

I've done this exact same repair on a keyboard flex cable. The repair is quite tedious, no question about it. The problem is the cable might break again in the exact same place if flattened, which is why it broke in the first place due to metal fatigue. Once flattened and "re-opened" it takes very little force for it to snap.

[@TheMatrix893]

Great job on the soldering of very thin wires, it's a nerve wracking, just a reminder note after completing soldering, you must always ensure that adjacent very thin wires do not touch, otherwise it will damage the prototype board when you connect the flex cable and make things worse, at least that what I always do.

[@RafalScrapper]

[@ageorgiev89]

I like using b7000 glue or just hot glue once completed. Adds to the strenght of the cable but won't break if you bent with force.
