It's really a good idea to heat the area of the PCB on the underside of where the IC is located to about 50degC below the solder melting point, and then use hot air at 30-50degC above the solder melting point on the top side of the IC. This causes the solder interface to reach the melting point much quicker dramatically reducing the stress on the IC. If you don't it takes considerably longer for the PCB side of the solder interface reach the melting point.
Try to put the IC on PCB not exactly in its place, but with a minimal angular or axial bias. It helps to detect the moment of balls melting - then IC 'jumps' in its exact position with the help of surface tension forces of molten solder in flux puddle. This 'jerk' is a good, well noticeable marker which allows not to overheat the IC. Thanks for video, +1.
Meticulous work - I'll tip my hat to ya. But generally with a square field chip you can use a generic square stencil. Even if the stencil pattern is a larger field. Just mask the stencil down in size with tape. Saves a ton of time and can save an aching neck. Keep up the good work.
yes i know it can be done that way. I used it with iphone s ICs. It just a demonstration of posibble way to fix something when you don't have special tools
i reball intel hubs(h61,z87,z170) GDDR5,GDDR5X, Nand flash, GPU 1050ti-1080 without stencil, first 5 times was wery slow, but now i make it really fast(sometimes i need to reball rare chips, that i have not stencil). You need just good flux paste and wery low hot air flow

I used to do it 20 years back. In those days balls and stencil was not available. Making balls manually was not very successful. We could not achieve uniformity. How I used to do was put small dots using soldering iron. Then file it away. Then again heat it and file away the excesses.
ive done similar soldering projects on my quadcopter flight controller, my friends thought i was insane and told me to spend the $50 for a new one. i didnt necessarily have the right tools but about 2 hours and some nervous hands later it flew like new 🤣
The chip in my plasma TV needed reballing. I was told that I could try reheating it with a hairdryer and may get a few more months out of it, if I was lucky.... I put a large chisel bit in my Metcal soldering station, and pressed down with lots of pressure on the chip. I also put solder on top of the chip to try and help transfer the heat. It worked and has been fine for over a year...

@@4X1000 Thanks very much! I worked with iphones motherboards for a 5 years , it was much more difficult, cause the size of the components. For example the balls on the iphone 6/6s is 0.25 mm . And of course the size of the chip is really matters. That one i rebolled in the video is not so big, it is about 400-500 balls only . And i can say that this type of work is all about the practise. All you need is a good soldering station , hot air gun , balls, flux paste , solder wick , flux cleaner, some hand tols and practise pratctise practise. I have some troubles with the shooting of the video cause i dont have a camera, i record with my phone, but i do my best to make more videos. You can watch the video about fixing the oscilloscope, sorry for bad english, and the foreshortening is not good at all, but it was a reaaly good repair. Thank you! :)
Are the vias under the BGA untented? I heard this can result in the vias sucking up solder from the balls, which could then lead to some unconnected pads.
Thank you. You need to put on a very very thin layer of flux to the chip. In this case your align tool will not take so much flux paste and the balls will stick to the chip. Then you should to solder the balls using hot air very low level. It is very important, because high level of hot air can easily blown off the balls. And finally the most important thing, you will never understand the process until you try it by yourself 😊
By the way i see you are a repair engineer. I used to be a iphone pro master up to 6s gen iphones and air 2 ipads. I have counted , i fixed approximately 3000 iphones and ipads logic boards during my 4 years career)))
Won't the chip get damaged with 390°? I've never had such a particular welding experience, but isn't it better heating the back of the PCB like a reflow plate?
It's better to heat it with a plate, yes. Sometimes you don't have that so you can use air. 390 is the temperature marked at the tool but I doubt the rework station is actually outputting that temp, and, if it is, the air is how the temp is delivered, so, you can control the tip height and take the air off the chip at the solder melting temperature
@@DciMaluko that's the point! The contact point may be at 300°C, but the chip (between the contact point and the tip) is much hotter due to its thermal resistance 🤔
4:40 - It’s better to use gloves when doing this, or use a lint free foam swab to spread out the flux. Doing it with your finger might transfer oil and fats onto the BGA footprint area which might compromise the reliability of the solder joints.
Unfortunately no. I tried to fix an LCR meter, so it is absolutely another kind of electronics. No schematics or something else. In case of 1080ti, let's hope it not a main GPU defective)))) did you perform MATS testing to check its GDDR memory? Your 1080ti has error 43 during driver installation?

Shouldn't have left the pads like this. Take a look at the assembly stencils, they all have holes on the BGA pads, as chances are too slim the balls will just solder to the empty ones. If without one nor any paste I'd just manually tin them slightly so that the package would have the on-pad solder to connect to. Also not pre-heating the board is a very bad idea, especially with the packages this large.
It is likely to cause bridging and cold solder joints due to insufficient material. And this process is generally good for mass processing due to its reliability.
Maybe yes it is. But i reinstalled it with the Plumbum contained balls , so the temperature to solder it is much less . So yea, it may be an option, but you can solder it without underheat, of course with propper equipment
Reballing is normally not needed the whole trend started with the ps3 and it was never the problem on that it was caps and if it comes to the point of reballing anything might as well replace the chip not just resolder it

NEVER use Rose's metal for clean bga. You cant full delete it from pcb, after time, starts metal degradation. If you have no way without Rose's, after Rose's use usuall 60/40(61/39) solder wire 2-3 times on pad

Great manual reball! Is there a type of flux that has a tiny amount of glue in it so the solder balls stay on better before heating? Were those lead-tin solder? Thanks, sorry it didnt fix the problem! Also, is it easier using a stencil & solder paste?
For the big IC's is better to use stencil+balls. For the small IC's (mobile phones , tablets etc) better use stencil+solder paste. I use Flux plus 6-412-a. It us one of the best non active fluxes. Yes, it is some kind a very light glue. But you should use your hot air gun in light air power mode

But i stiil have some tools and i sometimes do some repairs for friends old iPhones such as iphone 6, 6s, 7 and previous. Also i have idea to buy some old defective ipads for very cheap price and restore it just for fun)) Two months ago i bought ipad 3 in perfect condition with rebooting problem. There was a GSM flex cable problem. So i restored it and liked so much , now i use it as my ipad instead of my ipad air)))
