That's why i don't replace chipset/cpu/gpu :((((((((((((((((((((

This is something I'd like to try someday: change a chipset or SOC with a very basic pre-heater and hot air. You have done it beautifully, Sorin! It's a real shame that it didn't work. I feel that most people won't ever realize how hard is that that you have done in this video. Well done!

Easiest way to cleanup pads without risking ripping pads is put super low melt solder on the pads with an iron, then use flux, low temp hot air and wick to dab and lightly brush the pads with tweezers.

After chipset replacement, you should almost always clear the ME region in the BIOS. But it probably won't help with the crack either.

[tomaszstarling]

An Epic try brother, you did everything perfectly but sometimes no matter how much you try it just won't work. Amazing video.

[Drottninggatan]

If you return the chipset then they will sell it to somebody else. 100% tested by Sorin.

[idelintodorov]

You can try reflowing the chip with the hot air station directly pointing to the chip. Add lots of flux. Lower the speed of the hotair station, lower the temperature to about 300C and do it until the chip shifts. You also may need to reflash the bios.

Simplest thing would be to find a same motherboard from used market like broken laptop and get the thing replaced. You are an expert and I don't need to tell you. But it is for educational purpose and thank you for making the video

[ericjarvie]

I hope people appreciate your hard work Sorin as its one thing repairing the customers beloved but broken laptop but faulty or inferior manufacturers supplied parts well thats another that just adds to an already heavy and overbearing workload...I swear i get physically tired just watching this and its no surprise to me to see inferior goods come through the post and you forced to work with them...but you always prevail and get there and you never accept failure so for that your an hero...!!

Just a tip on using wick whithout ripping pads: cut down small pieces, and use a larger tip.

[antonioveloy]

An infrared machine can be obtained second hand via eBay for not that much money... Ofc it won't be easy to get into reballing with infrared and using stencils etc. but it's worth it if someone would like to learn the process and always better than using just hot air. Everyone hates desoldering chipsets and CPUs and the only way I do it is with a reballing machine, the risk to fail is to big even if our hot air station is a good pump. Love your vids btw., keep it on!

[jonathaningram]

I think I can speak for many, changing a chip set is very stressful and many won't even contemplate doing so. I personally wouldn't do it. Top marks for effort.

[аватар-дт]

Sorin, don't be sad! You done great job! the videos like that are also need. it is not always win in our work, all good. at least it is a practice and expirience. you are good

[ratos]

Sorine, ai facut totul impecabil. Deh, asa e viata ...

i've been doing bga soldering for many years, and i noticed that if the corner of the silicon is cracked, that doesnt necessarily have to be a damaged chip, since the circuit on the silicon doesnt reach the corners, thats why it might still work fine, happned many times with my long years experimenting with those chips, but generally, if the board have a bad chip that means the board reach a bad level and many components might already be badly damaged and finding whats bad takes a lot of time to figure out which makes the whole thing not worth it,

one more advice, dont try to solder the chip with small nozzle tip when using a small heatgun, heat will be concentrated on a small spot, and might cause solder to not be soldered evenly or cause the board to burst a bouble, use the blower without a tip and try to heat the board around the chip a little

i miss the old days before the BGA technology started, every thing was much more simple and it wasnt hard to change big chips

[steveb]

Thank you Sorin for another entertaining and interesting video. I never really trust any items as tested working. If you take your chip, surely it cannot be tested after it was re-balled as it would surely need re-balling again etc. It's the same as people selling phone screens, unless there is some device I have not heard of that will test any screen out there you would need a open phone for every model you sell a screen for. If I am doing an injustice to the sellers then I apologise.

[marksutherland]

As others have said, cutting smaller wick pieces not only makes it easier, you can hold the hot air gun in the other hand to keep the board temp up to make the whole process alot easier. Don't get me wrong, I wouldn't attempt this, unless I have 2 identical boards to see if it worked, I'd replace the board but great skill without question.

[anthonydenn]

Unlucky Sorin, nice job reflowing it though 😄 I think that damage on the side is from a chip holder that was used to reball the chip. Maybe one of those traces next to the damage is broken, couldn't really see it on the video well enough, but the damage looks pretty close to two traces.

[berberger]

I would recommend preheating from the back with a boardpreheater and use a square nozzle in chipset size for the hotair from the front, so you can be more save that you didnt burn anything

[francisjah]

I like the way you handle failed attempts. you're the MAN

[ppv_gh]

Please get another chipset.
And a tip for BGA chips: use leaded solder to clean the pads before using the solder wick, it lowers the melting temperature of the board pads and has a waaay lower chance of cold solders when installing a leaded ball BGA chip.
