Is that music or a hearing torture device?

So this means most gpus dead due to broken connection on bga or chip ?🤔

Looks like minutes are actually hours! Thanks for the tip... now I need Cramolin!

How do you know if the chip is aligned?

Where did you get the heat stencil?

I'm still learning this discipline, however, though my ignorance, I can recognize the great amount of attention and meticulousness put into the job. Congratulations! Yes, actually I would like to ask some questions: 1) what if the board has twist or bow? can you suggest a strategy to straighten it before soldering back the chip? 2) you said that the cooling system of that motherboard is inefficient: which temperatures cause the joints to fail over time? can you tell which laptop is? (Maybe it is a Compaq Presario or something similar, because I recognize the board, I have this model, and suffered of bad cooling system, improved by making the heatsink contact on the CPU. And I needed to isolate the capacitors surrounding the die with thermal pads, because the contact with the heatsink caused a shorted CPU)

can I shoulder it with some kind of glue?

I don't have a temp sensor but i managed to repair an MXM graphics card for an Asus X70 series, really cool tutorial for all to try (August 2024)

I got a flash light I'm going to try to fix but I don't have any tools. Could you list everything I need to get started. I'd really like to start repairing stuff like this

how to test if soldering is good without assembly?

my LC100A for some reason is concerningly inaccurate above values of 200uF

Within seconds of opening it up, how could you tell it was the lm311 to blame?

I don't think there is anything like that spray available locally. What is the alternative which is easily available?

Nik, i hope you can still reply, i have a ps4 board and the ps4 has been sitting for 6 years, i don’t have a available oven to bake it in, except for the one we use for food but i won’t use that as fumes may come from the board, can i place the board in front of a heater that is probably 60 degrees celsius or maybe slightly more, and leave it in front of the heater for a week? how many days is my questions and if this is viable method. Thankyou

You need to put a bit of solder at end of the sucking heat tool , it works better

Pls provide a full schematic to how to make . Bga machine like this?

Still working bga machine? 😊👍👍??

No to conducive tape

hello, thanks for the tutorial, do you know the name of the micro usb port? there are many different models and im trying to find this one. thank you!

I've been known to just remove the old micro usb port and solder power wires to the pads. The postts are trash and break to easily.

Very good

Did it ever happen to you that after fixing with reflowing a graphics card that had artifacts or even no screen to show image again but VRAM size is 0 MB and memory bus frequency is UNKNOWN? It indeed happened to me, so i am going to reball the graphics card, however i think i will need to replace the chip. Am I right or it's just an issue with the balls below?

Could you tell me what temperature you have your soldering tip at please?

use liquid flux and put some on it on the gpu chip side to side

Nice work, but one question, why would you need to remove the flux from under the chip using IPA? What's the risk or danger of leaving it there? Most BGA issue are dry joints so if you had flux residue remaining under the chip it will help the joints not dry out I would assume?

Do you do BGA with that hot air station?

Do you use magnification to do all that?

Excellent work in a time when almost everything defective is trashed, and replaced rather than repaired, refurbished, and serviced.

ОТЛИЧНО!!!

Hi, I am going to use mesh instead of hot air station, is it ok?

great demonstration of the concept, though a poor man's (me😂) version of this is to simply use a lighter on a safe part of the pipe, if there is condensation at the region where you test then definitely it gets cool fast.

What about if glue under the chip?

Is this also possible on my snes mini? USB micro broke after a few hours of use. Would love to keep playing on this one instead of emulating the games I want to play. Thanks in advance!

I gott this exact same model from the Nvidia HP class action settlement, should have just kept my media center laptop with the borked wifi and the oven temp GPU. I see why they settled the suit with this laptop, it was just as bad if not worse than the system they got sued for.

Hi, where did you get the needle syringe thing from for dispensing flux?

Can I use a 30-watt soldering iron?

Wow you made your own hot air station and put it in old receiver box 🫡👍🏻

You focused all the heat on the chip. Would this imply that it is unlikely that the open is occuring somewhere else on the board? Would heating the other side of the board be effective at all? Also, if the solder becomes fluid wouldn't the little components just fall off the bottom sde?

hi nice video do you got the blue print of creating the bga station

what happened if we did not pre-heat the whole board before start soldering ?

Thank you for the nice tip with thermocouple!

I've always burned the board 😅...

😮❤🎉

Thanks for the video. My Sony Vaio came back to life. I followed the procedure completely and everything was successful the first time. All recommendations for your work!

Very very good

awesome :)

Wow thank you so much for this and the 2nd video with the upgrades. Out of all the DIY solutions out there this is the most affordable one I've come across. Hoping to try and build one to use for PS3's

Or drop some pure acetone with a needle along the seal line and thanks carve it with a sharp hobby blade, it'll directly melt the ABS plastic.

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?
