@@perkulant4629 Don’t think he was disputing that. He was calling Sorin a legend for doing so. I repeat what you said because I think EarthSouthside is doing exactly that -- not disputing the first comment, but just agreeing that Sorin is a legend and appreciating his skill
Lol yeah I suppose owning 3 repair shops 20yrs experience i wasted that $ 6000 dollars per bga rework station ? No they paid for themselves over and over, Sorin just doesn't have experience in bga to use one.
I soldered a USB 3.0 controller once in the same way. The chip I bought came with the soldering balls but I had difficulty soldering it right, I think I made bridges. But after ironing the chip solder balls and the solder on the board, and after using the hot air and a little bit of pressure with the twesears at the end it worked fine. Thanks for the video and the tips Sorin.
I watched this, got amused and reflowed RAM BGA chips on two Raspberry Pi 4 that I failed to fix earlier 🎉 Thanks a lot, all of it really works - no need to be afraid of pushing BGA chips down a little, now I know 🙌🏻. Best regards from Kyiv, Ukraine 🇺🇦
Soldering skill is something so overlooked. My father taught me building a home computer in the 90's, and I've been able to keep my kids laptops running and up to date for years.
About 2 years ago, I replaced all the ram chips in a Dell notebook without reballing and it still continues to work fine. And then I have other chips the same way you do, without any problems. Why make it difficult when easy goes too 😉😁
you are sharing secrets of this job[things we are doing every day]and i can say thank you for not repairing other kind of job than laptop repair😇😇😇 we learn this on a hard way years of hard work and no one to tell us......
How I did this in the past, I used solder iron to mix the balls with leaded solder on chip and on the PCB. This decreases the heating time of the chip and reduces the risk of baking it. Also I tried to leave the balls larger like you did it first time because if the chip is too close to the board you can get cracked joints or broken pads because of cold-heat cycles. To be sure you will have a lasting repair leave a little space between chip and PCB and always use leaded solder, it's much more flexible
@@lela8714 Not sure what is the perfect solder, I am using Brofil 60 type 2.1 Sn60Pb40 0.5mm for small stuff or 1-1.5mm for larger stuff. The thicker ones have more flux inside. The point is to have Pb content, the rest is based on experience using it. And remember: rosin is your friend
@luminousfractal420 What fancy packaging kester solder arrives in little cardboard box. It went to quality and thin wire you know how thin is kester solder like very thin thin wire get lucky try to find that in china.You know that the tinner the wire faster you will solder.And it will make you solder joint like mirrors.Here are some properties of kester solder. Industry standard for decades Excellent solderability to a wide variety of metallizations High activity rison core formulation Leaves bright/shiny solder joints after reflow Standard Core 66 (3.3% flux) Dont be stupid if you don't have money or you're cheap to buy quality stuff dont spread misinformation.Dont assume give me facts.You think people like Sorin and Luis Rossman are ignorant and they are buying these types of solder for nothing.You will not get similar results with that cheap shit.
Omg I didn't know this, thanks alot sorin, I used to reball and do all sorts of crazy stuff, I didn't know I could just push back down, I always thought I would get a short
I agree on small BGA like in the video that works. No reball is required. Very practical. But go bigger, like PCH or CPU/GPU and you need reballing. In addition the original solder balls are mostly lead free and susceptible to cracking.
I love how genuine you are Sorin 👍. So much bs on TH-cam but listening to you has restored my faith in humanity. So grateful for your channel ❤. I believe the best fix is the simple fix. I have tried to reball a chip before and it was near impossible without a scope. The only reason I did it that way was because lots of people just say you must use 0.4mm balls and a stencil. Listening to you explain it just confirmed what I was thinking in my head at the time. The pad will only hold so much solder if it's from my soldering iron or fresh balls it won't make any difference. Thanks again for your videos I loved this one please continue 👍.
I got a load of knackered boards with various smd chips on and just practiced taking comonents off and on, and of diffent sizes, also while learning managed to get alot of components to reuse, saving a lot of money.
I agree. The 2nd method is my favorite; literally you have 1/2 ball on the chip + 1/2 ball on the landing. Melt them together with flux and whalla. One thing I have wondered, though, is the connection. Most will not care because if it works, it works. However, I am a quality-oriented person. Properly soldering means using the solder not as the connection, but rather the material that holds a good "mechanical connection" in place. I sometimes wonder if the terminals are floating with the solder between them making the connection ... and is this type of connection less-effective due to solder not conducting at the same speed/quality that a true mechanical connection would. If you know and feel like commenting. Thx.
I was always told the solder balls create a slight gap between the chip and the board, which aids in heat dissipation during the chip's operation. Directly soldering without spacing can lead to heat buildup and reduced chip lifespan.
No. Air does not conduct heat very well. The longer the solder, the less heat transferred to the motherboard. The motherboard helps spread the heat out. Now if the motherboard was hotter than the chip, and there was a fan blowing across and under the chip, then that would be true.
As putea multumi pentru video asta, majoritatea spune ca daca nu faci reballing ca la carte, adica cu bilute nu va tine prea mult timp, curios! Nu sunt din domeniu dar imi plac videouri-le tale si-mi place ceea ce faci, te urmaresc cu drag desi nu stiu prea multe din acest domeniu, deaia sunt si foarte curios, zi frumoasa !
That no lead stuff anneals after time and cracks, flux and reflow usually works fine except when the pads lift... and knowing that only comes from experience... And Sorin is a master of "if it ain't broke don't fix"... Thanks for easy pizza
Hi Sorin. great stuff. What if we have bridge under the chip? does it cause the chip burned when get voltage? And can you do one more BGA soldering for chipset/cpu ?
YES! Been doing this for years.... Just wasn't gonna share me secret because the strident "know it alls" go beserk and just didn't want to deal with it. They won't argue with Sorin, as he always does dodgy repairs.... ;)
So you are saying I didn't need to order these 415 reball plates? I also don't need these ten jars of 250k solder balls of different sizes? OOOOOF! I should have seen this first. lol Got them if I need them I guess. Great video Sorin.
Hello Sorin, thank you very much for the video, very good content. A question about USB testers, I have Fnirsi FNB58 connected to my laboratory source, the tester turns on but I can't get the USB-C output to power the laptop to negotiate any voltage with it. If I put the USB tester through the laptop's original power supply, it does. Any ideas? Thank you
This is a very small square chip. The reason why you should reball chips is the curvature of the pcb and the chip. They are not ideal line , the are both more or less curved. The bigger the chip the bigger the space between the pcb and the chip. You need solder balls to take that space. They also give some protection when pcb bends. But the reason why your repairs work is that all products are after warranty / end of life and noone cares if they work 1y or 5y more.
90% of repairs will be like this one. Of course it would be hard if not impossible with larger chips but that's not something you'd do in the day to day repair business.
Will not work when raballing CPU or GPU. Smaller chips why not, I was swapping them without new solder balls, but with various success rate. Then you are wandering if the chip is faulty or you didn't do your soldering job property. Also some IC are more fragile then others. Just an opinion, interesting point of view Sorin.
Ha ha NF few days ago did one when he showed reballing and EC chip using stencils and so on meticulously. Another method here but I sense there is a bit of competition between you too in a subtle way. May be rivalry 😊. Soap opera 😂

I can't understand how you're desoldering a bga chip in 20 seconds with no flux and no pre-heating. Sometimes it takes me more to take out a freaking capacitor. What's the trick?
@@charanebot6423 My hot air station is not a fancy one, but I checked and the temperatures are as expected. Seriously, when I see YT videos of people desoldering stuff I always feel like they're speeding up the footage.
@@IlBiggo OK. I get your point. Sorin has showed in his one of his previous videos how he uses max temp and max air to remove it. And I've seen Louis Rossman suggest similar in one of his old videos too.
So now we are finnaly ready to reball the cpus and gpus ofcourse only with proper calibrated wires. Do not overcomplicate things by using expensive hot air machines, preheaters, stencils etc
You can't do bga soldering without expensive hot air machine, stencils and etc. Sorin: hold my beer 😂
The drag solder with sorins thin liquid on both the chip and board works. It’s like half a ball on one side and the other half on the board ❤

What can I say besides it makes perfect sense its simple it needs to be soldered so solder it
helpfull and loved it
Nice video Sorin.😊 One quick question.Can shorted screen kill motherboard and CPU.?
Steadiest hands on the Internet, Great craftsmanship!
At times Sorin's videos are the real life version of those iffy looking electronics repairs in Star Wars!
Hi Sorin thanks for this. What is the flux your using for this texhnique. Do you think the liquid rosin on your shop would be acceptable? Thanks!
morning sorin I have watched you reballing a VGA before. But all is Good 👍
NIce , Just Nice Sorin .. The Best
Hi Sorin. great stuff. What if we have bridge under the chip? does it cause the chip burned when get voltage? And can you do one more BGA soldering for chipset/cpu ?
one off the beast video 🥰
Thank you boss
Hmm, what about new phone circuit boards? which are 2 to 3 inches in size 😅
yeah probably if you are doing a iphone cpu you need to reball since too many balls but the space in between so close to each other
Stating the airflow too could be useful.

Yes, not on phone chips too!
What about bga chips where solder balls can be trapped under the chip?

I always called the EC chip Super IO (or SIO). Is that wrong?
Closer to motherboard beter cooling 😀
Hey sorin have you tried this with a cpu + pch combo?
