hi am a huge fan of what you are doing i wich to have contact with you if you have facebook or instagram in order to improve my self in rebaling thank you for your vidéos and i wich you all succes :) ps: sory for my bad english
I'm impressed that you came up with this system at home and it all works. I work in the electronics industry, may I give you some constructive criticism? 1. Consider using a grounded work station. 2. Find yourself the datasheet for whatever solder (balls) it is you're working with to better refine your reflow profile. You want to ramp up and hit your peak solder temperatures within the specifications of the solder (more so when re-installing the BGA), this will increase reliability and result in a better solder joint. 3. Be careful as to not get solder into any open via holes (if not tented) under the BGA while cleaning the pads. You don't want solder wicking out during reflow causing a bridge. 4. Mask off any nearby components using solder masking or flexible heat shielding. Additional heat cycles on some components (electrolytic capacitors!) can reduce their life expectancy. 5. Don't touch the component once it's aligned on the PCB and you're applying heat. BGAs, as long as they're close and not bridging pads should generally self-center during reflow (to some extent). 6. Generally when performing rework or heating up components and circuit boards you want to bake out the board to remove moisture. Moisture can and will expand when heat is applied and can cause permanent changes/failures at the PCB and component level. I'm not sure how you would do this at home, but a few hours at 90 or 125C (IPC/JEDEC J-STD-033) would greatly reduce the stresses on the board and it's components. 7. When reflowing, it looks like you're preheating the assembly from below which is great. Professional rework stations tend to use smaller nozzle tips (the aluminum tent above your component) to apply heat and at a lesser distance. The nozzles are usually only slightly larger than the part. They tend to be channeled internally to help distribute heat to the top and underneath the component. You generally don't want to get most BGAs over 245-260 (it varies depending on the part). These channels help prevent the top of the component from getting too hot while still applying heat to the bottom terminations. I enjoyed the video, I hope you continue to refine and improve your process. I think you've done really well!
Thank you for your advice, i build this station 3 years ago and i'm still modifying it, i also try to learn as much as i can about reballing, as you saw i'm not an expert :) , i also hope that other viewers read your comment and benefit from it.
Thanks for these advices. I'm slowly getting into (precise) soldering and want to get into BGA repair. One thing you mentioned on number 5 (don't wiggle once aligned): I think he wiggled to make sure solder pads make bridges with the board properly. I can imagine that it increases the probability of making a bridge, if you wiggle it a bit.
Dude this is awesome I´f seen other youtuber do this with professional equipment but you just made it your self and it works! This is a real display of craftsmanship and you got balls align the GPU and PCB without any tech just eyeballing it. Grate work Keep it UP!
Thank you very much, i made this rework station 2 years ago and i'm still modifying and upgrading it. I'm not an expert you know , i learned reballing by watching youtube videos and searching the internet for information, btw aligning gpu and pcb is the easiest part ;)
It's not that big of a deal. When i was 18 i was put straight to uBGA soldering without no training at all. The only difference in tech then was the fact that we had a bigger heating station than this, we still had to eyeball everything.
This man has got a cool Setup going on here. I wish I had something like this. I’m big in to computers and components, and I have been for years. I’d like to perform more extensive repairs like this.
Dude you are amazing. I’m seriously considering buying all the tools and watching tons and tons of these video then just go for it. I have tons of broken Motherboards and Cards. BUT can I make one suggestion???? You should do a voice over after you edit the video explaining what you’re doing and why your doing it. Maybe explain where the memory controller is, etc. GREAT WORK MY MAN!!!!
I've seen too many others who use the braid well past it's capacity to hold solder. Once the braid turns silver, it's full. Time to move to a new section. You did that and to top it off you fluxed the braid!!! As a man who has been an electronic tech since the early 80's. I am very impressed. Finally, someone does it correctly. Well done!
You're so creative and brilliant, those tools are improvised but worked perfectly like an expensive tools in the market. a new fan here, liked and subscribed...
Was expecting equipment people might actually hope to DIY themselves, then I see your equipment is still essentially professional-grade. Impressed and disappointed at the same time! Bravo.
men you are a real pro, no high end tech, all craftmanship, you are awesome, men you must become a teacher or something, we need a real pro like you, on our schools, please continues with you work, looks amazing, i going to see your video of how you build you own workstation, i want to build one
Reminds me of when I had to replace the I/O controller on my Intel Mac Mini, except all I had was a soldering iron, hot air system and had to bake it in the oven to set the chip! Has not given me problems since, I bought it broken, realized nothing could communicate and that was why it would not boot, bought a new I/O with solder balls attached, removed the old one "took forever with a hot air gun", cleaned the board, removed old solder and had to use screws to level the board on glassware baking dish! Had to set the oven at 420F and bake it until I saw it completely drop, but it was a fun experience! I saved quite a bit compared to buying a used intel mac mini and it works without issue, with the money I saved I maxed out the ram, replaced the cpu, replaced the 80gb hard drive with a 500gb one and had an unused extra DVD burner that I installed! Most of the work I am used to doing is with car audio, so I figured it could be no different than repairing an amp!
Can't believe I watched the whole thing. Very nice dude. I just gave a little more life to my gpu that it started artifacting and freezing the system only while gaming, by heating it with a hot air gun. Don't know if it is going to last but it's something. Keep up the good work !
Hello, if you heated the gpu enough for the solder to melt (~230°C) then you did a good reflow, if not... the graphics card will start artifacting again or even show a black screen, use a good thermal paste to reduce the thermal stress to help the repair to last longer.
i am going to attempt this to my r9 380 today. Card is in pristine physical condition, I assume the problem lies within the BGA solder. Ill make sure to heat it up thoroughly. This video gives me hope.
This is a very cool process and something that hardware enthusiasts with older hardware could certainly take the time to learn how to do since the alternative is much more expensive solutions. This also provides the opportunity to add a rather useful skill to a resume! Personally, my only concern about this is the use of paper towels rather than something like a lint-free cloth.
I couldn't stop watching, I really enjoyed it. i was just doing some research because I have a specific PCB that I'm not getting a replacement for so it need to be repaired.
Very impressive video sir. How ever, none of this would be necessary if it were not for BGA. I am sure BGA technology lowers the cost of manufacturing circuit boards, but the failure rate is way too high. I would gladly pay more upfront for reliable pins and holes instead of those damn little balls. I currently have a Sony PS3 FAT and a Microsoft XBOX 360 FAT that have both quit working. In both cases, it is almost certainly a BGA problem. The cost of re-balling is more than the machines are worth.
Hello, i totally agree with you, because technology is evolving fast, electronics manufacturers don't care much about quality and durability, the thought is that we will buy a new faster graphics card or a new game console after a few years anyway, they make us buy electronics like they are consumables. And in many cases if one device dies, the repair is too expensive, we are left only with one choice, to buy a new one.
Hey epic video? But where did you get that reball sheet and do you have to get unique ones depending on model or are they universal? p.s where do you get those balls with lead are they legal?
Thanks, i buy the stencils and solder balls on ebay, each chip needs its own stencil (usually same series chips use the same stencil), i don't recommend universal stencils, yes it is legal to buy leaded solder :P
Hello, i didn't get notification for your comment :( www.ebay.com/itm/Direct-Heated-215-0807018-215-0807007-215-0807027-215-0807105-Stencil-Template/172333111211?hash=item281fda97ab:g:nc0AAOxy14VRMwKj
Good soldering work but before you went as far as re-balling did you reheat the chip to see if that cured the fault (albeit temporarily)? If not, chances are that heating the chip alone fixed it, not the re-balling. Without any form of commentary we are left in the dark.
Hello Steven, just heating the bga chip would probably in most cases make device work again but this is not a repair and the result will last only a few days or weeks, most people at home bake the boards in an oven to "fix" the problem but they repeat this procedure many times because the result does not last long and eventually this trick stops working for them, only with reballing or reflow you can repair bga cracks or if the chip itself is problematic then you have to replace the chip.
How does reballing last longer? When you bake a board and that fixes it, means that the internals of the chip have some kind of problem and will sooner or later die on you.
@Tiger White A lot of people cant experience ASMR, and gosebumps so it may look dumb for them. From my observation it works mostly for introvertic people. But calling something dumb and insulting someone intelligence because you dont understand it makes you look dumb also.
WOW That was incredible. Thank you for sharing!!!!! I think the comments below say it all on your BGA work Station. Looking forward to more videos on your BGA workstation....
if i knew your skills i would keep my favorite laptop chasis and just "fit" whatever motherboard and cpu and gpu within their sockets, voltage and whatever else, i mean, think about the responsible reuse and reduce of the ecological footprint this makes ;)
You can't, not just only because you can't swap between BGA cpu's and gpu's(in some laptops you actually can but they are going to give some errors anyway and isn't worth the risk), no one sells BGA chips, cpu's or gpu's, literally no one, you could buy a broken laptop motherboard and then repair it and fit it in your laptop chasis, but then, you will have to find a laptop motherboard that has your same laptop display connector
seriously man no words for your work just mind blowing.i have watched several videos on this but you are best.its really hard to stop or forwarding your video..Awesome work....
Kill the sound a little and mix in a little soft high paced audio. ;) You know what... after watching the video completely through... Dang. You did amazing! You sir are a true craftsman!
Hello, watch my new reballing video AMD HD7950, ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-HoprTmwKfDk.html i test the graphics card after reballing
Hi Nik Telio can you please help me... i have hd7770 that stopped working hdmi and DVI ports after i used bad hdmi cable for half minute...but displayport still working... i measure voltages on HDMI pins and DVI pins on cable end from gpu and i get 5volts on hdmi pin 18 and dvi pin 14... but on hdmi pins 15,16 i get sometimes 1,42v sometimes close to 2v and same on pins 22 and 23 on DVI where supposed to be 5v what should be problem?
Hello, there are some small electronic components on the tracks that go from the gpu to the video outputs, they act like fuses to protect the gpu and you need to replace them (i am not 100% sure about this, never happen to me) i pinned your comment to the top, if someone knows more about this problem maybe he can help you.
@@NikTelio Thank you so much for responding, later i found out even displayport won't show anyhing with Displayport to HDMI adapter, but works normaly with Displayport to VGA adapter, and i found out if i connect to DVI port DVI to VGA adapter it show picture, but that is because it is using Analog legs from DVI output...so basicly all digital signal are gone from gpu and only analog still working... This is how gpu looks like without fan and heatsink... ftp.chinafix.com/forum/201706/11/194845iwpapymlarayum3r.png if you or someone else find spare time to help me, like circling what components to check i would really appreciated :)
Lol I thought this was a "how to" video... looks like more of a "See how I made his impressive rig that can do things you otherwise can do only in repair shops" video...
Dam....impressive man impressive. You just took all that high tech professional certified bga reball and made it practical and clean using homemade tools............ pioneer shit right here man...pioneer shit. I was trying to get someone to reball my PS3 without paying an arm or even do it myself, but since I don't have a work space, and aren't as skilled in handwork as you my options are limited.
Thank you, repair shops asking a lot money to do this kind of repair, but you have to think that this is a 3 hour procedure and requires a BGA rework station witch costs about $700-1000 and a skilled technician.
Nik Telio well I think I already may have reflowed the solder joints to their limits(I put the board in the oven 400 degrees for 11 minutes twice, first time lasted about 4 months, second time 30 minutes, and that was WITHOUT flux) board still works though no damage, just YLOD. Reflowing will still work?
man that was pretty impressive , the whole process and your own home made tools really nice, i only have one question , the components on the other side of the pcb , did they move while soldering?
really good man. I just know the soldering but ur video shows clearly what's reballing or how a chip with out leg is heated and soldered. I heated my GPU and it didn't work. I saw u r video once and put the soldering flux and heated again and then its working. thanks man .
i'm glad i could help, so you did a Reflow, if you follow on this video the first heating phase (235-240°C) and you don't lift the chip and let it cool down again it is a perfect reflow.
@@NikTelio LOL Anyway great job. You've made stuff yourself that even some of my fellow engineers at work don't know how to make. And I command you for that :)
I understand and it's really really appealing...but why? The choice of repairing items for one of the fastest markets in obsolescence. Really hypnotic btw...it's like a deep meditation.
Hello, repair shops ask a lot of money to do this repair and only if you have an expensive GPU or laptop or something worth repairing you consider the repair.
Man that station is amazing you inspire others like me to do the same, thats a good ides greets from Costa Rica. I have a question do you do your own flux or you buy it??
Thank you :) i made a new reballing video , you can watch it here if you like : Reballing Sapphire Radeon HD 7950 ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-HoprTmwKfDk.html

Yo I watch this and I'm really really intrigued I build and sell computers and repair various electronics. I am just 3 off from being a master auto mechanic just getting into electronics witch was pretty much my passion this is my first time seeing something this in-depth and I do nothing but want to learn. I was just making my own tools all this is just what I am looking for and I would do nothing but love to learn how to use them. I'll definitely subscribe but it would be really cool to here you explain more of what your doing and how to do it.
You're like some kind of Cyberpunk Goldsmith... your work is flawless my friend!!! 😯. I wish you worked in my city to send you a MBP with its crappy AMD Radeon to replace/resolder it... but.... Glitches and Overheating... 😔
It would be great 🤣 Jokes aside... I just found some tricks to boot up ignoring the AMD kext and force the OS to boot up using the Intel integrated GPU in my i7... so... temporary fix I guess... Thanks for the reply!
in some cases if the amd driver is not installed the os ignores completely the amd chip and works only with the integrated intel gpu, others just remove the faulty chip from the board so they wont have any problems with it for long-term solution and the system works only with the integrated intel gpu.
I found this article (apple.stackexchange.com/questions/267581/gpu-problem-boot-hangs-on-grey-screen) wich was like heaven sent to me because I'm in the middle of a recording session. In this article, beside the boot and kext modifications and scripting... there's another solution: lifting one resistor from the board. It cuts off the GPU supply, making it unavailable. So... maybe it could be useful for you. But my other question about de AMD GPU issue is: Is this problem due to a bad designed chip getting scorched or a "lead free" solder microfractuing the pins on the connection?. If so... my greatest fear is that due to the repeated heating and cooling cycles of the board this could lead to a bigger problem... This notebook was poorly designed thermally speaking... Shame on you Apple!!! Fans running at full speed for you! :P
Hello,in my experience there are many factors for this kind of problems, yes the chip was designed not to last for lifetime because we use electronics like consumables, they use now lead free solder to build the chips and lead free solder does not like thermal stress :P , computer manufacturers also many times on cheap laptops design the cooling system not to cool the graphics chip well to increase thermal stress to fail after a few years of use so you will buy a new laptop (you would anyway because technology is evolving very fast and your device gets outdated after a few years)
