You make it look easy. Thank you for all the details. Question if I may. Do you prefer all 90 x 90 stencils or do you use another holder for smaller stencils. Looking to buy and so many options out there. Great video.. Looking forward to learning more from your channel. Good luck with your channel. Best wishes.
I initially started with direct heating stencils but I really sucked at it. I used to make a lot of errors. gradually I moved to 90 x 90 and I felt more comfortable with it and over time the errors nearly vanished. I found the 90 x 90 to be more forgiving but it is a matter of getting used to it. For me, I got a better finish with 90x90 than with a direct heating stencil. That does not mean direct heating is bad. Some can get a similar or even better finish with the direct heating stencil. It's a skill you will build over time. 90 x 90 stencil and holder are more expensive compared to direct heating stencil and its holder. If you can try your hands on both direct heating and 90 x 90 and check which one suits you the best and whichever you feel comfortable with, invest in that route. For starters, memory would be a nice place to start. You will also like this video th-cam.com/video/iArDb1-2UvA/w-d-xo.html
Hi, thank you for the video. May I ask, what size solder balls are used on GDDR5X and what hot air temperature are you using when melting the balls to the IC?
The video is great, thank you! Detailed explanations. But where can you get suitable stencils? Each chip type has a different layout. I have some classic graphics cards here such as the 9800 Pro, 6800 Ultra and 5900XT with artifacts. I think the video memory is defective or no longer has proper electronic contact. And I'm trying to figure out how to get it back. The cards are too good to throw away.
I think the best place to find stencils for your cards is Aliexpress. You would also need a stencil holder.

I just found out, that GDDR6 stencil comes with many size versions, like 0.40mm and 0.45mm. The 0.40mm is not correct, but would work still. Samsung datasheet says the formed ball diameter is 0.48mm.
No I have not tried. I do have solder paste and the stencil for it. It's just that I got too comfortable with solder balls that I never tried. Someday I would give it a try.
@GraphicsCardRepairs-tk7ql It is less messy than having to deal with so many tiny balls all-over the place. Direct heat is applied to the small stencil. Not the 90x90. It won't work well with something that big. I like your videos my friend. Please keep them coming and slowly but surely your channel will grow. The more videos, the more you get out there. I stopped posting for some time and my channel suffered because of it. But I'm trying again. Wish you the best 👌 👍🏼
@@GraphicsCardRepairs-tk7ql Just apply a thin coat. Then wipe the surface with a clean cloth until there is no more paste over the stencil surface, only in the holes. Just like you did on the GPU reball video. Start with low air speed (@350) from one corner, air speed at, say 20. And stay there until you see the balls coming. Then slowly bump the air speed to 30 and move slowly up until whole surface has balls as you move. Remove stencil very very slowly while it is still warm. Don't wait for it to cool down too much. You're a pro so I think all this goes without say. I'm just sharing what I know :)
No when you say identical it should be the same model number and brand. For example, if the GPU has Samsung installed with the model K4ZAF325BM-HC14 then the replacement should be the same model of the same brand. Installing any other brand or any other model will not work irrespective of the BIOS. The same goes with Micron and Hynix. No BIOS flashing is required when you replace the faulty memory. Now if I have to swap from one brand to another i.e. if I am planning to replace from Samsung to Micron I would need to swap all the memory modules on the GPU and also change the straps to tell the BIOS which brand is installed.
@@GraphicsCardRepairs-tk7ql many thanks! Was trying to fix my 3070 with a faulty vram is there anyway to pinpoint the faulty vram? the NVIDIA MODS is not working it's always giving me 0000003 error code so i do not know how to pinpoint the faulty vram itself.
Man, I never understood this sport. Especially when it comes to memory. I just drown it in some good flux, take my iron and apply it to the chip and THAT'S ALL! Then I just fan it onto a cleaned and fluxed pcb, obviously. Yes, sometimes have to repeat, but so do "ball people". Sometimes even use sn42bi58, or that Mechanic 158 wire/paste to make it even easier. Anyway, I could understand stencil+paste, but man, I grew old watching your method. So many people died while you reballed that ddr. Why do you torture yourself that much? And, btw, this is no criticism against people who do "industry standard" while truly being part of the industry. Like, if you have a specialized repair shop in which bga is big part of your job (I also do repair, but mainly old, good, expensive audio equipment, mainly type A amps), then ofc you're gonna have a 1000$ microscopes, and a 1000$ fan mounted on articulating arm - TO BEGIN WITH. When you have million stencils on top of that, having bunch of bottles with solder balls is really no problem, though it would be, even for those guys, if they had your "calm" hands. Also, if you're, like - a robot, capable of placing 10 balls in 1 sec without any stencil to help you - I'd say, go for it, robot, you're doing a great job. But you're not, you have shaky hands, even my hands are calmer than yours - so there's nothing wrong with adopting the appropriate method for your hands. Calm hands are NOT a skill, this is simply a medical question. Look at Louis Rossman, that guy has his own company and is an influential repairmen on the national US level, but he has no problem adopting methods suited for his shaky hands. You could do that job in 1/5 the amount of time with just a stencil, pair of tweezers (or helping hand, just to keep it stuck to chip) and a heat gun.
😁 wow. Thank you for sharing your thoughts. I know this video was quite long but that deliberate for anyone trying to learn reball. I really had to be as slow as possible. You can take a look at my other videos as well. 😁. I do have other stencils and paste too which I use sometimes, it's just that I am more comfortable using the ball method and I am able to reball a larger number this way. It's just me maybe. Just to be honest I can do both 😁. I will think which ever method works best for you as long as you can you can get quality work done. Sometimes if I really have to save time I just use the bulk ordered memory which is already reballed from the factory. I appreciate your feedback and thank you for sharing once again. I hope you like my other videos. 😁

For all the balls not stuck in stencil when removing it, the four dial in corner must adjust in order for all balls sink in stencil holes
Hi, thank you for the video. May I ask, what size solder balls are used on GDDR5X and what hot air temperature are you using when melting the balls to the IC?
For gddr5x the ball size is 0.4mm. air temp is 300c

Have you tried reballing using solder paste instead? works real good!
No I have not tried. I do have solder paste and the stencil for it. It's just that I got too comfortable with solder balls that I never tried. Someday I would give it a try.

Welcome!
hi, just asking if i replace my VRAM with an identical one, do i need to change the bios or not?
No when you say identical it should be the same model number and brand. For example, if the GPU has Samsung installed with the model K4ZAF325BM-HC14 then the replacement should be the same model of the same brand. Installing any other brand or any other model will not work irrespective of the BIOS. The same goes with Micron and Hynix. No BIOS flashing is required when you replace the faulty memory.

Are you using the right mats version?
what was the size of balls for gddr6 ram
0.45mm for GDDR6 and 6X
