- How to Reball Packard Bell TK81 - Acer Aspire 5552G with Homemade BGA rework station and low cost equipment, the laptop shows black screen, bad cooling system design caused the northbridge to overheat and fail, this laptop was previously repaired by repair shop but the repair didn't last very long, now i will reball it my way and hopefully the repair will last a few years :)
Why Reballing ? The chip is soldered to the motherboard with many small solder balls (BGA) and one or more solder joints crack with time due to the thermal cycle which creates thermal stress (contraction and expansion en.wikipedia.org/wiki/Thermal...) and the laptop stops working, old thermal paste-pad or paste-pad with bad heat conductivity and clogged cooler increase the thermal stress, with this procedure we replace the solder balls and resolder the chip to the motherboard and the laptop works again.
If you have any questions just ask me :)

Very pro procedure! Nice one!
Nice Sir. Thank you, for video. GodBlessing
Fascinating watch !
niko thank you good job
Excellent Job!
Great work man
So Cool! Thank You.
Great job man
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?
thanks for sharing! May I know what kind of soldering tip you use for desoldering? thanks!
Hello, the tip i'm using is this one
www.ebay.de/itm/SOLDERING-IRON-STATION-Tip-T12-1403-FOR-HAKKO-FM-203-FM-204-FM-206-FX-950-FX-951/261541688936?_trksid=p2060353.m1438.l2649&ssPageName=STRK%3AMEBIDX%3AIT
Great! Congratulations! Where do you sell this white infrared ceramic plate?
Very very good
beautiful
how do you do ball to ball alignment with this?
hello you good 1 respect bro Soldering station
how many watts thanks
Wow very good
Thank you.
how did you convert your DVB to BGA rework station !!?
How did you connect the top and bottom heating plates? Do you use some kind of dimmer to measure the temperature?
both heaters are connected on the PID controller and according the temperature profile it controls the heaters, it uses K-type thermocouple to measure the temperature, i'm also using a power regulator for the to panel
Very good! But I have a doubt. Can I connect these direct heating plates to 220v without damaging them?
yes but without a thermostat or some kind of controller if you leave the panels working they will get very hot even glow red,
high power panels need some kind of controller, low power panels you can leave them working for hours without problem
Would a dimmer be used to make this temperature control? It is only a temporary measure while the other pieces do not arrive.
yes a dimmer will reduce the power output of the panel and you can keep it under control
The video I didn't know I needed. I need this equipment. How do I make it?
but my question remains, how do you source your stencils? i am now in the proces of building such a machine and i want to firt try it out on an old graphics car for which i found a stencil. but i also have an old laptop with prosumably a bad pch bud i wouldn't now where to get the stencil. any searching tips?
Hello, i buy all my stencils on ebay, just search the chip code and you will find what you need
jonathan beibier you think you have the capability to reball a PCH on your first ever attempt lmfao 😂😂😂😂😂😂😂. You will fail, I say that with certainty.
aqib2000 haha never claimed it would be succesful xD, but it would certainly help the lerning experience if i have the right stencil hahah
aqib2000 heck i don't even know for certain whether it is the pch at fault xD, but idk i just want to reball shit for now
i reflowed my first gpu yesterday. before the reflow the board beeped "gpu problem" - after the reflow i got picture, install and run win10. on first glance, graphics good, hardware manager reports ok.
yet i cannot install the newest graphics driver else than whql.. detects no compatible hardware, and directX test (userbenchmark) fails, i suppose the chip is faulty.
thanks for the video!
Thanks!!!
Excelent !!!
Merhaba ben bga IR 6600 modeli kullanıyorum.Ekran kartı ve laptop anakartı tamiri yapıyorum çok başarılı bir bga makinesi tavsiye ederim her marka model çipleri rahatlıkla sökerek takabiliryorum.
Exelent
Mantap bro,dimana bisa dapatkan BGA seperti itu.
De la escala del uno al diez de doy diez
how do u know when to replace bga chip? is it short component near bga chip?
if you heat up the bga chip a little then the laptop starts working again and then you know that the problem lies on this bga chip.
What is the exact model on the bottom Heater? and we're can I find it? Is there any chance u can make video tutorial on how to make on these genious machines
Hello, watch this video and in the description you will find a link with the parts i used to build it th-cam.com/video/yOoBdcpfc5U/w-d-xo.html
Hi thanks again for replying but the parts of list is not complete for example it doesn't say the model of the bottom Heater u're using and as well the top one
so you are saying that if you click on the link and you get automatically redirected to the sellers side, the seller does not mention the model ?
what number the air level for that 260°C heat, and what is the name of that solder tips for removing the old solder balls because i cant find it here in my local store
YOUYUE 8586 hot air station, T12 1403 soldering iron tip
i mean when you applying a new solder balls with the stencil you turn on the solder station to 260°C, and what about the air level of the solder station, what number on air level you are using?
i set it on max (10)
are you serious??? i get on other channel it must be set to the lowest level, mine is 1 to 8, so i set it to 1 air control and 300°C temp control heat and the result is my stencil bending or flexing, you remember right the first time i asked about that, thank you Nik i will try that, thank you so much 👍
it did not succeed Nik, my rework station is Quick 857D, i tried using 260°C and air level 8 (max), my stencil still flexing (ps3 rsx & cell be direct heat stencil) just the same result with lowest air flow.i dont know what caused it, maybe the stencil were too thin, i dont have any idea of it
Hello. You reballing chip what was the problem of the laptop.what the material you used Karim from algeria.thanks
Hello, the laptop powers up but the screen remains black, usually this problem is caused by overheating, reballing or replacing the chip is the only solution, i used 0.5mm leaded solder balls, some flux and desoldering braid
bro pls share u r diy bga rework station making video or docs
parts list etc
Can I ask you something about laptop, so I have a HP Pavilion gaming 15 with I7 9750H with GTX 1650, 1 month ago when I want to turn on my laptop it won't turn on, all of the indicator lights are on like battery indicator LEd lights, power button lights. All of them turned on, but my screen don't want to turned on, even the fan didn't want to turn on too, after that I go to the Service Center and they said I have to change the motherboard because they said that either my CPU/GPU chip broke or the ic, they said it happen because of overheating.
So is there any chance my laptop be fixed and worked again?
Sorry if my English bad, but I really need your help bout this😢
On such graphic bga ic there are also some smd caps which can easily displeased !!!!🤔🤔
@Nik Telio That[s a flip-chip, bro..Reballing doesn't work with flip-chips - you have to replace whole chip, because this failure is caused by soldder boalls directly under the silicon die... You can heat it up to 120 degree C. If it will work, chip needs to be replaced for sure. Reaballing is only a temporary solution, so it will fail soon or later... Usuially it lasts max. 6 months and fails again... Even Louis Rossmann made a video about that and it said that it doesn't work that way with flip-chips... It may help with singls bga chips like Vran,/SIO aka keyboard controlers.
Can you try doing a PS3 launch model reballing?
Do you have some good and not very expensive flux to recommand ?
Hi, for reballing ?
Nik Telio Yes
i'm using Warton Metals Future HF SMT Rework Jelly, cost about 20euros 10g, in the past i used Chinese Kingbo flux...did a good job and very cheap but not easy to clean :/
And a little question (might be stupid ) why don't you protect some of the components with kapton tape to protect them from the heat ?
kapton tape does not protect from heat well, you can use aluminium tape instead, sometimes i do use tape to protect other components like nearby bga chips or vrams but most of the time i don't, i never had any issues :/

Come si chiama il macchinario che fa il reflow reballing?
Where did u get the tip I can't find one
is the T12-1403
www.aliexpress.com/item/1005003096683649.html
❤
👍
what is your flux type?
i use the Warton metals bga rework jelly and liquid rosin flux
man that's a lot of work for a "disposable" laptop. Interesting though
HI NIK
show me plz how dit you for the spatula tip , iwant build one for me
thanks
Hello, watch this video th-cam.com/video/W5HECI1L3dg/w-d-xo.html and in the description you will find a list with the parts to build it
your station does not support T12 tips, you must buy the T12 controller the T12 handle and the T12 spatula tip
what is that cable for ? 1:49
This is a K-type thermocouple sensor and it measures the temperature near the BGA chip.
Can you please put subtitle on.. Thanks!
tools?
🎉🤗💯🙏🇧🇷
Fan fungction??
This is what happens when you let your teacher do the repair.
it is going to fail again , the problem not with the solder joints it is in the chip itself , so re-flow and rebelling both are not a reliable solution
So how to solve it if reballing failed?
Use flux "No Clean" .
all my fluxes are "no clean"
FC.
Unfortunately the repair has failed (the last portion of movie with the main board function is fake, you copy it), but I appreciate the work you put in it, and I like your rebelling station, I know that you put a lot of effort in it, even if the end result is bad, and for sure you end up disappointed after a lot of effort invested, sometime things in life does not go as we want (the chip was probably bad). I will give a like to the video, it worth it, the work done is really good, Thanks for posting it, for people like me that has never done such a thing, ...
that will only work for a short period of time. reballing is hard EVER worth the effort.
