If you solder 2 balls before , the alignment will be easy and perfect. I'm a small notebook board repair and your videos are helping me a lot...Thanks so much for sharing.

[@Vexcenot]

Heh 2 balls

[@Multimeter1]

More GPU fixes. Amazing! Cheers from the USA 🇺🇸! Right to repair saves the earth!

[@KrisFixGermany]

Thank you. Repair and recycle ♻️ is the right way.

[@maraisl]

Great work! First time I have seen reballing done this way. Very clean!

[@KrisFixGermany]

Thanks! 👍

[@paolomonai9511]

Good evening. I am really impressed...never seen this before! You can spare heat sensitive semiconductors from being shocked by too much heat. Congratulations for this smart approach. Regards from Italy.

[@kamikazekk-df4vz]

To be honest I never thought to reball the board and not the IC as I did till now...... However when I see something new I would try it as soon I can, so I could try to use this method monday morning when I go to the lab, I'm really curious about what (disaster) I'll make........ Anyway thanks a lot to share your skills, very appreciated.

[@TheKoodus]

how did it go??

[@kamikazekk-df4vz]

@@TheKoodus I prefer to reball the chip instead the board.

[@freemanmed5009]

i don't have a reballing station, so it's very useful for my situation, thanks a lot, very nice technic.

[@Se7en20082008]

Wow, this is amazing work! I've never saw a reball done this way, and didn't think it would be possible. I must admit throughout the video I was wondering how the hell you remove the stencil and when you whipped it straight off I was like 😮Fantastic video and I learned a lot from it 😁

[@Guraba_AzE]

Gute Arbeit! Für ein erfolgreiches Ergebnis muss man unbedingt eine gerade Stencil und frische Paste haben.

[@user-qy7cv9rd8m]

Excellent buddy, thx for video. I did reball of my 1060 directly to pcb using 0.45 balls a week ago for experiment. it seems to me best way not to overheat gpu.

[@BucifalulR]

May I ask what tool you used to solder the GPU? (brand and model)

[@khirobey6261]

Hallo ! Interesting technique to reball, can you show us the other part of the precess ? I want to see how can you align the gpu perfectly on the balls if possible :D, great job

[@danielsatko-]

it selfalign just like with normal reball. cleaned pads sits on balls

[@RetroRepair]

I'd really like to see your process for installing the new gpu, did you film that?

[@TechnologyHive]

Thanks for the information, Kris! You are helping me develop my skills in this area. Watching your videos is like being in a classroom with a cool teacher :)

[@trouble_maker023]

Love it, that's actually really smart since the PCB is not as heat sensitive, brilliant work man

[@chauto5987]

For you guys to know more this is the way to reballing phones chip like, nicely done sir/ p/s: you promised me to explain about Micron memory faulty situation remember :)

[@KrisFixGermany]

Thank you. I have the perfect example for Micron problems now. The video will be uploaded soon

[@Multimeter1]

Is this related to GDDR6X or micron DDR5/DDR4? Some context please as that’s super concerning for my 3090

[@KrisFixGermany]

DDR6 - D9WCW in 2000 series cards

[@chauto5987]

@@Multimeter1 I have no clue either, I think we have to wait for him to enlightening us. But I do think that the DDR6X or/and DDR5X Micron problem,cause not long ago I've successfull replace 1 DDR5 1GB Hynix Vram chip to a faulty 1050 Ti with 4 Micron memory chip(3 Micron and 1 lonely Hynix chip after repair cause unfortunately I don't have spare 1Gb DDR5 Micron chip), it run perfectly fine about a year now without any problem.

Excellent video once again! Really cool to see a clear reballing video. Thanks a lot!

Very good! Gratz from Russia!

[@user-p2p]

Hi. Can you tell me what model of pre-heater you have?

[@larryrodriguez1977]

Well I know what I am gonna be practicing later today on my donor boards! Awesome tutorial!

[@classmaster]

Very nice technic, pretty simple but quite professional procedures.

[@cota0036]

why would you do that? if to solder balls to a pcb first, it will be difficult to fix any troubles on it because pcb has a lot more thermal conductivity and you will have to preheat it first. it also heats the pcb twice (first on ball soldering and the second on gpu soldering)

[@Podi0620]

very smart this inverse way of reballing :D Cheers from Hungary !

[@tonycstech]

As soon as I saw solder paste and stensil on the same table, I figured what you were about to do. But thank you for the details.

[@J.P.Tech.01]

Amazing method, thanks for teaching us. Can you make a 2nd part where you solder the chip an explain the method? You think this method is also great for video ram? Activate the suscriptions perks so we can donate and contribute with your job and channel! Thanks a lot again!

[@KrisFixGermany]

Thank you. I can make a second part, but the soldering process is simple. You can use this method for every PCB if you have enough clearance to place the stencil. You can also reball the chip with this method.

[@danielsatko-]

interresting method. thanks for sharing

[@orlandocarnio]

hello my compliments for the job , but i think the boards unfortunately not all has a big area without to have near smd elements around the chip . thank you anyway is a valid alternative.

[@skutterbuster666]

Nice, i'm going to try this on a spare card i have. It would be cool to see a follow up to this where you mount a chip after reballing this way. Anyway, thanks for sharing that method

[@roslavlskii6275]

Я делаю также только на гпу единственно что мне не нравится это размер шаров. Также делаю с чипами памяти.

[@drgpu7968]

Thank you Kris for great tutorial.

but , i heard that soler ball resiste heat more then soldering paster

[@solidstate90]

Where can I find the application tool your using ??? Is it some kind of underfill scraper??

[@cyb3rgh0st]

Hi! Nice tutorial! What should be do if the stencil starts bending over? Is because the stencil is bad quality? Apart of that, is there any technique that you could teach us? Thanks a million for your time! 🙏🏼

[@charlesnefdt7783]

you need to balls deep it from behind. sorry for my english.

[@sebastiandenenfeld9886]

You are my master! Im wondering how to reball chips , thank you Chris !.How to solder gpu after that,do i need bga station?

[@KrisFixGermany]

Thank you. Actually I’m using BGA rework station for GPU and RAM. You can use this method for every BGA chip if you have enough space to place the stencil

[@mikegaming4924]

There is risk that stencil would be stuck to the PCB ... put tiny kapton tapes under the stencil in every corner , then it is easier to pry off.

[@northwestrepair]

It will also allow paste to squeeze it's way under where you don't want it. For that reason, this method is unpredictable for large area like that because these stencils are warped.

[@mikegaming4924]

PCB prevents the stencil from warping that easily. You can also use lower temp solder paste and only use underheat to form the balls, which eliminates any warping. Krisfix also said in the video to not push the paste too much, otherwise it goes under the stencil. But yes, sometimes this method needs couple tries to get all balls to form properly. Also you need to check the height of the balls after first application&heat. If some are lower and smaller, you should reapply some paste there and heat it again.

[@mikegaming4924]

I once again tried to place the kapton tape pieces to the corners, and like northwestrepair said, this caused the solder paste to seep incorrectly. The stencil has to be without such corner tape pieces, otherwise it will be too high up from the PCB surface.

[@ritzh2908]

This video is something for gerrepair he has to learn how to do it like you. For soldering the chip do you apply lots of flux or yust as less as possible yelly or fluid?

[@KrisFixGermany]

I use Warton metals. Less is better

[@emindmail9648]

excellent tutorial

[@umpoucodetudo5983]

you are the best!

[@radius.indrawan]

great work! is there any advantages of reballing the board rather than the chip? or just a different approach?

[@KrisFixGermany]

Basically for GPU reball you need to heat the chip 3 times ( remove, reball and install). With this board reballing process you can heat the chip only 2 times. Decreasing the heat stress.

[@radius.indrawan]

@@KrisFixGermany i see.. thank you for explain me well.

[@user-nd2on6gd2i]

wait a sec did you reball the board not the chip, this is the first time I'm seeing this method. Aline the chip on the board after will be hard ,i think if it work for you the it mean it is possible.

[@carmelorossitto7084]

Why don't your ball solder to the stencil? When I reball, 20% of the balls solder to the stencil. I need advice

[@mira5751]

How reliable are the connections with the 138 degree solder after the board has been working?

[@pamdemonia]

Amazeballs!

[@Jason-zh7wo]

Nice technic 👍 I will try this, thanks

[@maziarrezaei]

Thanks for the great video! That application tool, where can I find it?

[@kakkoishonen]

I really like this method. Can we do the same thing with the RAM chips? directly to the board?

[@KrisFixGermany]

Sure. If you have enough space to place the stencil
