- Removing and soldering big BGA chip WITHOUT any preheating tools. Experiments with Agilent Scope
I decided tryting to remove and solder big acquisition chip without any preheating tools. Only hot air gun! Lets go!
I'm sorry about terrible views with my hands, i'm so sorry , i did this operation in "live mode", i hope you will enjoy this.
Experiments with Agilent/Keysight DSOX2012A Oscilloscope
I did that with Quick 2008 Hot Air Gun anf Quick TS1100 soldering stations/
Best cheapest chinese soldering soldering stations in my opinion. - วิทยาศาสตร์และเทคโนโลยี
Omg it takes some extreme amount patience to place those BGA balls one by one by hand! Props to you!
The man has got "balls" 😉
Very Impressed 👍😎
thank you!
Thank you for showing us that for one off BGA repair in hobby, you do not need expensive tools!
i almost had an heartattack when he said "wrong chip position" after that time consuming reballing process. anyway well done.
haha. yea it so funny ))
I could watch all day long. Very impressive work.
thank you!
Well done. I hope you make more videos!
Well my friend that was awesome to watch
thanks pal
Without stencil?? Thats really tough one...Bravo dude..m
thank you!
Well done !! Perfect !!

Nice video! Good job :-)
How do you determine the chips alignment ? The ball grid array is equally balled, how do you know which way to seat the chip ? In chips interfaced with pins, there is a mark on the board designating where one (1st) pin is supposed to go and the pin displacement is recessed on that corner .
In some cases there is a special marks on the board to help you to align the chip correctly. If not, before desoldering the chip (when chip is soldered to the board) i usually make some marks that will help me to align the chip when i will solder it
You did a good job ! 👍👍👍
Thank you!
12:27 that is the happinesss!
patience lvl 👌👌
The pcb did not bended due to the lack of preheating all of the board?
what temperature and blow speed did you use for reballing? nice job
It is up to the thick of the board . In this case i set a 450 celsius
Thank you for making this video. Im wanting to get into electronics repair mainly game consoles. Im on a limited budget when it comes to tools because I don’t want cheap tools, I want tools that will last. This video saved me money on stencils and an RBG station. Now that I know it can be done by hand I will just do that. I have a lot of time on my hands so I don’t mind. But your video has given me confidence to do it! Thank you for showing us this!
Before worrying about repair you need a sound understanding of electronics.
If you understand the basics you will not need to ask questions like you did.
@@greenpedal370 this is all part of the learning. You learn by asking questions and growing your knowledge with books along with experience.
@@elijahwolter9235 That's where you are wrong. You need a good theoretical understanding of the basics first. If you jump the gun you will pick up bad habits and get confused with pseudo science.
My advice would be to join one of the branches of the services and train there.
If you are up to it they may even put you through university to do engineering.
You get my like just for the soundtrack.
Wont heating the chip for so long damage it???
500 degree is to much . Thinking using infrared will speed the process,??
dude, you got waaaay more patience than me. lmao good job
Nice work. The heat makes me nervous but then I read that it's not just a heat gun. What do you think Agilent used for bonding heatsink to chip in this product?
Thank you. I'm pretty sure it is a thermal glue.
What's your hot gun setting?
❤thank you so much ⭐️⭐️⭐️⭐️⭐️
That's an impressive experiment!
Mind to share, did you replace the chip, or just reball it?
Just reball. It was an experiment to see if it possible to reball big IC without preheating table using only hot air gun . Yes , it possible but better don't try this :)
Ótimo trabalho... parabéns
No it's not good to use products that har parabens in them.
You want to get a preheater when soldering on these boards , and ramp the heat slowly , then add the air to the chip at around 130c
doing it just buy heating it up with hot air is way too brutal and ceramic caps can break , glass diodes break and you can get popcorning of the board and flexing ... meaning the board wont work at all.. great vid non the less
Can this be compensated by distance moving?
Thanks lot
When you use Rose metal, doesnt that tend to corrode? It looks like you use it sparingly, & remove any left over solder with flux, wicking cable, & iron. Thanks 🤓
No it doesn't. As you said just remove left rose metal and that's ok. Rose metal is super helpful for many soldering operations such as connectors removing or preparing IC's for reballing. The main point using the Rose metal is to reduce the temperature of soldering.
@@fixthetempo7276 yes, thank you again 🤓
Temperature setups for soldering? Edit - found it Thanks
Nice
thank you!
How do i know which solder ball size i need
which temperature do you used to solder the ic?
It is up to the thick of the board . In this case i set a 450 celsius. Also i must say that it is an experiment. You must solder the BGA with preheating table
@@fixthetempo7276 thanks, yes i agree
How do those little balls stay in place after you drag them? I mean before heating them.
because there is a thin lay of flux paste on the chip i apply before gettin the balls
how did you line the chip up to the pads
There is a little marker on the motherboard
Can you work on Panasonic car radio for a VW car?
sorry , i can not, because i am from russia and i am in deep full of shit
How much airflow did you use? Thanks mate 😊
In the case showing the video - 450 Celsius with 100% airflow. But those numbers are much approximate. And it depends from many things such as the board thickness, the size of the chip, the room temperature and the model of the hot air gun. So it is all about practice, practice and more practice
@@fixthetempo7276 yeah. I soldered and reballed myself a bga chip this week 35x35mm, I got two hot air stations the cheap D636 I think it is (very low max airspeed) and the atten 862-D (very nice one) I used the cheap one, but only with way to low temperature. I will try again with ur settings on the atten, the chip didn’t settle down. Nice vid thanks
How much would you charge to "repair" an ipad? Thanks & hope you are fairing well these almost dystopian days 🤓 did I see right? You didnt use flux to help remove the IC? Also, what brand of heat gun or hot air rework station do you use?
it depends of the type of problem and type of difficulty. For example 2 years ago i took approx 50-60 USD to repair tristar IC on ipad mini
@@fixthetempo7276 by repair i mean replace the nand, give it a new s/n, & load ios version whatever will run on the ipad. Do you live in the US? Thank you, & no, i am not an apple spy. Thank you. Its taking a discarded but working ipad, that i found, & doing a hardware mod to make it so i can use it. REWA technology has a video, but they are more to sell the equipment to do that. Thanks the repair on the ipad mini, did your repair fix the problem? I assume so, & how long did it take?
@@j.lietka9406 sorry for late answer. Unfortunaly i am from russia(oh shit). For example i made an ipad 2 mini for my wife by replacing the nand and write new SN, for customer it was approx 80 USD. It was 5 years ago. Now in russia we cant say what will happen next day
@@fixthetempo7276 well I hope you don't get drafted to go to Ukraine!! It used to be possible to do that to certain models of iPads, but not sure about nowadays. I find PCs, laptops, Chromebooks, in dumpsters, and curbside stuff. I found 2 Mini Mac's still in the boxes in a dumpster I check periodically. Couldn't believe it! Unopened, unused! But they are 2018 models, but still like new! Thanks! Hard to hold on to, but be safe my friend! Your English is excellent!
@@j.lietka9406 thank you my friend. Unfortunatelly i am already has been drafted, because i had to serve a regular time in russia military in 2011-2012. But now i am living in another area, so right now i am free man. But it is unreal to hide in place like moscow for a long time, i do not know what will happen with me and my wife (she is a doctor and she is military used to) next day . It is not my war and i do not want to take part in this. Sorry , but now i am reaaly dissapointed and i checked all my old videos to like my subcribers and i want to thank you especially for you support
Fun to know there's another thing to use/way to remove & solder a CPU. I wonder how many Computer Repair shops/services actually know this lol (most don't know, don't have the tools, &/or are scared of computers/devices made before 2015).
I smashed a camera, the support told me I could try reballing the sensor so I guess I'll try that before buying a replacement, it's nice to know I don't absolutely need a heating station. How do I determine the size of the balls? Just the size of the pads=diameter of the balls? Also, I just have a no-clean flux pen as of now, is flux gel a necessity or will my pen suffice?
reballing the sensor?? are you talking about a CMOS image sensor?
When you arranging the ball to each tiny pad (4:00), it looks like the ball was attracted to the pad by itself? 🤔
It is because of speed of the video in this part (x7) ☺️
hey bro my laptop is giving error thermal sensor out of range and in dell diagnostic i have a error thermal sensor out of range the sensor i guess is faulty and is giving out of range error it is dell g5 secondly because of this laptop is not showing discrete gpu not even in device manager and it is running on intel hd graphics what should i do i have changed bios thermal pasted it and cleaned it but not solution video thermal sensor is giving like readings randomly even in negative do you have any solution?
model is dell g5
What was the fails before to do that?
No failure. It was just an experiment
what is that thing?
What is the danger of damaging the chip itself with the heat?
in the case like this video - no chance. Because of the package of the chip. Other cases is very individual and it is very difficult to recommend something
How can I send motherboard she is a bga chip problem
500 С????????? why so high
It’s better to keep it at 250 longer than to overheat the chip and board. How did the chip even survive at this temperature?
wondering How the balls were not blown away from the pads when hot air strikes
Sir i need stensels kindly help
I'm surprised that people panic when their CPUs hit 90 degress, but here chips are hit with 500C.
these chips also aren't doing anything when being hit with that kind of heat
nice work hahaha
big up! who are Your Favourite youtubers? Also, Let's be youtube partners Xd
Reballing without a stencil? I don't think so.
Is this called reballing?
Yes it is.
500C might have killed the chip but it survived this time
it is because that this BGA chip has a case like a faraday cage. I think that it had not been damaged with the temperature much more than 500 C :))
It seems like that but this may be the air gun port temperature. What the die sees is probably just above soldering temp when the balls collapse ... ouch.
Hello my friend. Do you think it is possible to make a powerful graphics card for mining digital currencies?
Well, Nvidia does... but if you’re serious about it, you really want dedicated chips; and cheap/free power. Look into ASIC-based miners, and a big solar farm to power it.
I'm trying to figure out how to make solder balls... wish me luck.
why? just buy it
@@fixthetempo7276 lol, I hear ya, I just wanted to see if it's possible to do.
Tell me about music
13:07 here is the music
high risk of failurre and to much effort, i prefer "half on chip, half on board"
500 c is fake temp max to 300c 500c will destroy you motherboard
hard work but not practical...sorry
It's practical for DIY home use but not for comercial.
