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 :)

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.

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

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

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

Thank you Kris for great tutorial.

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 😁

Vielen herzlichen Dank aus Kassel für deine informativen und lehrreichen Videos !

Very nice technic, pretty simple but quite professional procedures.

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

thx from spain,.,.nice work

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.

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

Nice technic 👍 I will try this, thanks

interresting method. thanks for sharing

excellent tutorial

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.

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

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

@KrisFixGermany

2 жыл бұрын

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.

what kind of stencil is it? looks flexible!

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

so you have to get all kinds of stencils for each type of CPU?

Hello how do you align the gpu at end?

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

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

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! 🙏🏼

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.

In früheren Zeiten haben so viele Sockets neu gebaut.👌

What fluxe are you used?

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.

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)

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

гуд !

neat

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?

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.

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

Жыл бұрын

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.

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

Is that a blank board?

just savede me hahaha

Geil, GPU muss gar nicht erhitzen. nur Board. vielen Dank.

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

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.

Aluminum foil tapes are more useful on Reballing.
