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.
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.
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...
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
@@SuperDikabraz nand flash chip of mobile phones? Are the balls small enough to fit in the pads of a cellphone nand chip? Any idea? What hot air reflow station do you use? Thanks 😃
@@zahinhossain9055 For mobile phones, better use Solder past+ stencil, specially for paste) If dont want to use paste- you can buy a lot of different balls from 0.2 to 0.6mm) My station- Quick 857DW+, one of the best)
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 🤣
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
@@fixthetempo7276 I have never myself tried to reball without stencil, as a matter of fact I have never done a reball lol! However, your video gave me some sort of confidence to try your method and I will. I like people doing complicated jobs without help of lots of fancy stuff. Thank you and keep up the good work! I will subscribe to you channel. =)
@@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.
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
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?
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.
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 🤔

Isn't there a way to blow the heat under the chip?
@@tricky778 The problem with that is that the amount of pressure needed to get sufficient air under there would blow chip off the board.

i think reball with solder ball best than ever, because solder reball had high temp thank solder paste. so this make long life for phone/devices

Craftsmanship in electronics repairing. Reballing worlds Picasso....
What was the device that you tried to fix? Was the FPGA from there also?
Mmm. I think it was E4980AL LCR meter. Yep, the FPGA was from another defective E4980
What if you used a string to organize the balling in lines. Then you do it tilted 90° again. Would it work?
i don't think it'll work because of the flux. the balls will get stick to the string rather than stay in each pad. but i could be wrong though..
Normally you have some stencil for that purpose. He didn't use one.
