For those curious about the price, this is roughly a $3300 card.
Dayuuuuuuuuum so what does it exactly do?
@@krnzzang84 probably used to connect NASA Supercomputers.
All of these caps near the PCI-E connector are AC coupling caps for the PCI-E differential pairs (data lines), they go to the main IC of the card. They always come in pairs, 1 pair = 1 lane of PCI-E. On modern cards the data lines operate at GHz speeds, and it is critical that the electrical properties of the two traces in a pair are as closely matched as possible.
Is this a repair or will this fail?
@@Splaterson92 due to the wire and the microscopic difference it gives in electrical flow i'm affraid this is a no fix...
I wouldn't be so quick to consider those mellanox Asics down for the count. In some competing products that I am more familiar with a signal to noise ratio of many millions to one is no problem. They are far more tolerant of electrical noise than they were even a couple of years ago. As I understand it it is less a question of "how much noise" than one of "how random is the noise"
@@mauzzz2418 Given that multiple PCIe extension ribbon cables have been shown to still work for a GPU at Gen4 speeds even when daisy chained together, I'd say there's a fair chance this works just fine.
@@Splaterson92 Typically in the industry, they extend via out using tiny wire to jumper to part; then secure bond the part to board surface.
That was one of my favourite repairs if I'm honest, it looked a no fix all the way to me with so many missing pads on the vias. Different level of repair at the micro scale of this card, such a clean and tidy repair when finished to. Great job Alex.
Today I didn’t see that coming as I once denied a repair of that type but I’ve just realized solder paste makes the magic. I had it even then but I didn’t even think about it, great job I’ve advanced again through almost everyday I advance. Thanks n thumbs up
I'm new to this. How does paste make it possible vs just solder?
I have been watching your awesome repair videos for about a month or two, I am really impressed by your hard work, your way of identifying the problem easily, and many of your motivating words. Many thanks for you. I am from Ethiopia and I am thinking about starting a repair business but I need the basic and amazing tools you use for repair like the V2 microscope, hot and soldering stations, thermal camera and so on... One day I will have a business like yours in my own country. Anyhow thanks a lot!!!
Good luck!
If i ever need micro surgery..... I'm calling Northridge Fix! Alex that repair was next level. 😁
Better than Factory (God)
It's a pleasure watching 'The Master' at work...👍
I can't believe how steady his hands very surgical and professional amazing so satisfying to watch 👍
These videos are teaching me so much more about PCB repair than I ever thought I needed to know. Thank you very much for posting these videos, the information alone is super valuable, way more so than any college course can provide. I guess experience trumps all huh?
Thanks for getting my order packaged up today and says its going out tomorrow with USPS. You taught me alot and I thank you so much for it Alex.
Your website should use a PID controller to calculate the *next* orders expedited shipping cost as the target variable based on the current price and the amount of expedited orders in the queue.
After some amount of time you’ll hit your steady-state equilibrium price.
You are both the repair man and the hype man. You do the repairs with the same tools you sell. Genius!
Also, I'd almost be in moral panic grinding away at those microscopic traces. You approach the task at hand with such confidence. Every time I've worked on small traces I get completely stressed out.
Great job!
Stress will diminish with lots of practice. You have to make mistakes to learn. Practice on donor/scrap boards.
On my way to work here in Ireland so i can't watch right now. But just want to thank you so much for all your videos.
They've helped me more than you can imagine to learn and start to open my own business
this recovering circular trace that i am talking about, thats why i loved micro soldering! this video absolutely perfect sir! Masha Allah!
You really have me sold on all the the tools and repair accessories. I almost want to buy it all and have zero experience with electronics.😄 But I like tools! You and your experience make it look so easy.
Pad length of a 0402 component is 0.6mm. He is able to grind a pad/via with a precision of at least 0.1mm and you can hardly see his hands shake at the end of a 10cm long tool under a microscope where a cotton swab fills the field of view. Incredible steady hands and skill!
You are a surgeon! How you do what you do is absolutely fascinating.
Superb repair as usual, I had feeling this was not going to be repairable with those missing pads but as always. you made the job look easy and looks great! :)
man your work is amazing. I just deal with ef amplifers ... smallest component is a 10 ohm 1/4 watt resistor. Such amazing craftsmanship....I just recently subbed and can't get enough.
Hi, I'm French and your videos give me a lot of satisfaction to watch them. That said, I think your videos would be best viewed with a neat and tidy artboard. Keep going like that.
That was tense! Crazy precision work!
This was one of the finest fix attempts of this channel, IMHO. Even if it is, as some are saying, a "no fix". I think it will work just fine. Great work!
Seeing that solder paste under the microscope and those impossibly small little balls was super cool.
Those kits with replacement pads are really useful. Other channels I watch don't use them.
This is literally surgery but on electronics. I love it.
Man, you are a wizard working with those tiny components.
I initially believed you were an electronics technician, but it appears that you possess extraordinary skills in electronics akin to those of Houdini!
I have watched a lot of your videos but I think this one is on another level. Manufacturing level.
I love hearing him tell it like it is thanks for the video
A work of art by a wise head and skillful hands.
Yes jitter has gone :D The amount of information people neglect to provide you astounds me
Well, I haven't seen this yet, that it fixes missing tracks in a very interesting and unique way. I like it
As usual you’re a legend man ! Good job 😊
Sir i love the way you explain your job deeply, Love you from Pakistan.
The Witcher of Repairs, amazing job.
micro component repairs are hard. props to you.
no wonder every next soldering-noob is trying first himself... you make it look so easy, its ridiculous! well done
Excuse my ignorance. Been watching you forever and I don’t do any repairs at all. But I’m always like “he’s going to use solder mask on that”. 😂. My question on this job is, why bother putting a pad? Kinds of seems pointless since it’s just floating in the solder? Again excuse my ignorance. Thank you and Merry Christmas!

Alex, this one is beyond better than factory...It Is Amazing!!! I am really impressed. Well done. Merry Xmas to you and your Family. Regards from Italy.
Master surgeon at work. Fun watching you work, habboub
Great job, that grinding pen is amazing 👍
Coolest PCB repair I have ever seen!
Simply amazing work
That was some very delicate work, you have a great touch. Nice job!
Wow! Very impressed about your workmanship!
Wow for me that's the most impressive soldering work you did since a long time on this channel. So small
after video private 😂 thanks for this video alex ❤️
I told they would . It has to be like 1000$ for expedited. Most won't pay maybe some but if they do you might want to do those first. Just for the cash . But 95 $ still is a bargin. So they will pay it. To many expedite to many to do in little time. Good luck brotha. Thanks for the content and keep up the good works.
Happy holidays days sir thank you for all your hard work you need break every now and then !
wow, a true craftsman. Excellent repair job. I can't wait to afford one of your microscopes. Almost impossibe to do a neat job without it. Nice tweezers too.
I always wondered how to fix pads where the traces are in a layer in the middle of the board. Thank you for the video.
You're a great guy, you have the advantage of good explanation
Did you test the card before and after? I know the problems were pretty evident and no doubt needed done, but I have to wonder what the issue was. For instance, was the card detected by the OS? Or just not able to bring up the connection etc?
I'm inclined to make sure it fails consistently first, then make then fixes, then do the same test and watch it work. Beyond satisfaction, it's nice to demonstrate in a video for the customer, etc
A line test would probably need a specific spf connector, a suitable cable and another device at the other end.
Personally I ask customers for any additional bits if I don't have them and not too onerous for the customer to bring in/mail in.
I am entirely impressed 😮 this I figured would be a no fix.
That's amazing pads restoration! Good job, impressive
That was a awesome job. crazy tiny. That microscope is worth its weight in gold.
when i saw the board first thing came on my mind that if i have to fix this board how i am going to fix it (no idea)
after watching repair then i know how it should be done
i like your repair and learn a lot form you thanks😍😍
Merry christmas Alex to you and the family. Thanks for the great videos this year
Another breath taking repair. 💕
That is something new! Thank you!
Truly incredible.
Hello first of all I thank you for your work I love watching all the videos and all the repairs and I have taken a lot of things thanks to you and I am improving little by little thank you and I have a question please: I know what product you use to clean the motherboard after soldering? I await your response cordially good luck to you
"I'm sorry, patient, but I need to grind some more" - Every dentist :)
Great work. Amazing. I hope it will work again. Thank you for that video. Greet
What is the purpose of using a pad strip for these torn via vs just soldering component directly to the paste?
Genuine question, no smart remark intended, or implied. It wouldn't given more support since the via is still the anchoring point would it?
What am I missing? Or is it simply preference?
the circular pad strip provides more surface to solder on to and it's more likely to make a connection with the via when it's pushed over the solder ball.
@@NorthridgeFix Thank you
Just here learning and having a cup of coffee ☕ cheers... Great video bro.
impressive repair, good skills sir
Great video!
I think you need to train a couple apprentice so you can handle your work load more efficiently.
Hi NF loves watching your videos every day I learn something from you as I have a passion for this electronic world.
I have a question.
1: When you say meter in Diode mode it means meter in continuity mode or diode mode if so what diode mode does it cause I know diode mode is used to check diodes.
2: What if we don't have an LCR meter can we still check caps with a multimeter but yeah for the inductor we need an LCR meter cause there is no option in the multimeter for measuring inductance that's what I know.
Very good Repair. I wish u and your Family a Merry Christmas.
Work of art.
Feliz navidad amigo,un saludo desde España 🇪🇦 aprendo mucho con sus videos.Un saludo.
merry christmas to your and your family mate love all your video watch them all the time when new ones out thanks lee.
This man is sick ur videos give me the drive to learn how to repair tech again amazing skills an knowledge
Maybe you could remove certain categories of items from the ability to have expedited service. If it is something that they could go out and buy, it doesn't make sense to expedite it. But special purpose parts or data recovery does make sense.
If everyone is paying for expedited, that means you need to raise your price for expedited!
Merry Christmas to you and your family
Very impressive, as to be expected!
I've been watching for awhile now and one time you told a story about how you took your parents vcr apart. I thought that was a funny story, maybe your new viewers would like to hear about how you took it apart and then had to fix it. I watch everyday even though I have no back ground in this kind of work.
Precision work 👌🏻 Finest work done & still you will have to Refund, you will not earn out of it. This is business.
It looks like there's enough room that the manufacturer could have located the caps higher up the board, which would hopefully reduce the chance of the caps getting broken off
offcourse they won't do that, the more cards get broken the more they can sell new ones.
Super precision work!
what a masterpiece of work, i´m very impressed 👍
You’re a life saver. Ty
Very very strange order. This kind of product is should be under warranty this is not consumer product this is enterprise grade network adapter. Your rework was exquisite
long story and if they were under warranty, I wouldn't have gone through this process.
saya lama subcribe chanel anda
saya terinspirasi untuk tetap berkarya walau di usia gak lagi muda
When you magnify so much you can see the metal in the solder paste.. you know its small
You sir are an electrical surgeon! Also, it sounds like its time to make expedited service more expensive?
Great work. Thank you
Great job Alex
I have a few broken DC motors from electric toys. I use the coil wire from their rotating part as jumper wires. I can pick whatever thickness I want from those motors. Unwinding them is easy.
You Could test the card in a pci slot to see if its being reco in device manager.
I ended up with a similar network card, but even more damage to it. Why does these cards tend to loose their components? These are nothing you just take out of the system to play with.
You measured the cap whilst it was soldered on the board? I might have missed him taking one off but measuring caps whilst attached on a board often gives false readings
Always watching and learning thank you salam brother starting my shop just need some tools.....
good job
new tweezers look top notch
How about Testing it?
The only book that I really want to read in 2023 is the SMD resistor and capacitor book
Like a surgeon!
U'r realy amazing guys Alex.,very great
