This video is great; thanks for sharing this with the world. I've found that good flux, patience, and a light touch with the iron and braid is the way to go. Here's an extra tip - clean the flux off with alcohol when the surface is still warm. Makes it much easier. If the part or board cools and the flux gets gummy or solid, add more liquid flux and rub lightly. It will help soften up the hardened flux, allowing you to get some alcohol and clean the area easily. Thanks again for this video 👍
Thanks for this turorial! I've never done BGA rework before, so your tips and explanation were very helpful. Will definitely be watching your DIY flood light machine video
Interesting video. Technically, you are at home yes. But my definition of at home is not with a BGA remover machine, more DIY sort of thing. The mistake is mine. Still a cool process though, thanks.
I have a video where I build the machine, amd also explain the cheap option how to build one using halogen flood lights. Have a look on my channel for this video, it explains how to use different options from cheap to expensive and on of the options is floodlights to build bga station
@@MaxELECTRONICS i want to erase the memory on the bga chip so its rest and ready for reuse i heard that if i use this device it might help esp8266 version
Remember it is impossible to tape unused patterns for every chip so many times you will need to order the exact stencil if Tape of as much as possible although all ball will reflow they will not stick to the non tinned pads so simply Clean off non sticking balls and clean and Reflow again without the stencil on the Jig. If the stencil is to low the balls will not release correctly if the stencil is to high then the balls will go underneath the stencil . Important to heat at 300 degrees with low air and start at one corner then the whole chip. Good Tutorial. Another good tip is to prep your bga chip with Rosin and Solder and a Hot air Gun then TIN the pads with 183 degree Solder # Very important if it is difficult to tin a pad it will have issues accepting solder paste also. Use 3D Stencils if you can find Them higher Success Rate. ! Pro Tip.
Very intresting, absolute good explained - now i know the difference between reflow and reballing completly. I will watch more videos from your channel.
Excellent video, you explain the process very well! I'm keen to do an upgrade of the embedded CPU in my laptop soon, and this vid has been the most useful-info-dense one I've come across
Thanks for the tutorial, this was very good! I've got an upcoming project where I need to do this, and your video was a HUGE help! Side note: At the very end, after you removed the tape, it looks like you have a nearby capacitor that desoldered itself... hope you saw that. :)
With 183 Lead Solder the Chip will self align as long at it is Close to the Correct alignment then once it reaches Liquid State - Specific gravity of the Solder will hold it in place and if you budge it slightly with your Tweezers then if will return to the correct position and you can be assured that the Chip is aligned properly also when you are watching reflow look for the Chip to drop and the solder Flux to overflow just a little then you should allow to heat for about 5 Seconds and then Test with the Tweezer for self Alignment this Technique is important because the DIE of chips is different and therefore the amount of heat that is required to reflow chips will vary so you must use Drop - Flow and Test Technique if not you run the Risk of Overheating certain Chips and damaging them and components around them by Exceeding the required Heat Dwell Time for that particular Chip . also there is a Phenomenon called Pseudo Soldering where components on the back side of the board are flowed so every effort should be used to reduce temperature on the back side of the board and surrounding components . Proper rework Technique is Entire board should be heated to 150 degrees and Even Heating of the Component to be removed should flow up at 2 Degrees per second never exceeding the Manufacturers Max TEMP Specs. by using the Drop -Flow and Test Technique you will never exceed Manufacturers Dwell or Sustain TEMP Max which WILL DAMAGE CHIP.
Thank you so much for this tutorial. Free information like this is what makes the internet great! One question: can you use isopropyl alcohol instead of paint thinner to clean the chip? Thank you.
Thank you for the informative and detailed video. I just invested in a more basic reball station gotten inexpensively from a console repair shop (T862++) and it does not have the automated processes like yours does. Would you happen to have any advice for the careful use of a more basic machine? Ive never done a reball before and will definitely practice on some junk boards as youve mentioned before any attempts at a dead ps3 but any other advice would be welcomed and appreciated. (Prep, machine temps, graduation of temperature, max temperatures, times and proper care of not burning the chip itself)
Best advise I can give is don’t rush it, be patient, don’t crank the temperatures up, it’s ok for the board to be heated longer, it won’t hurt it but it’s not okay to raise the temperature to get it done quicker. It’s a time consuming work, so just be patient and take brakes in between tasks. And add flux if old chip still doesn’t pop off.
Thank you for this great video😊 You were very detailed in giving the instructions, make me want to this myself now. I guess I have to look for some old board to start with.... In the past I have tried to reball a PS3 which was not succeful, hope to have more luck with you instructions. Thanks again, I will definitely subcribe to now channel ❤
Does it require the exact stencil for each component being worked? There are so many variations it seems it'd be difficult to find. Particularly if you have rows and columns that are vacant, and need to remain unpopulated by the balls, if using some universal stencil that has a full grid pattern. Seems it'd be a very tedious process to extract them without disturbing the adjacent balls, since they can't simply be left in for removal later.
@@MaxELECTRONICS is it worth doing so? I’m referring to the GPU chip of a card that was used in a 2010 iMac. All these computers had issues of faulty GPU cards after a period of working while being overheated.
hi... thanks for the video... i ordered the same reball station some weeks ago and just reballed my first bga chip... works pretty good but needs some exercise ;) thx
Very good explanation how to do a reball at home. Ill do that process on VRAM GPU and i have doubts but thanks to your video. I have more clear how to do the process. Btw, could you link the package of the support and the balls? I would to buy all that set. Thanks in advanced and cheers from Mexico !
I’ve been thinking of getting into rebelling as hobby but is it profitable as a business because I’ve done basic console and laptop repair but I want to get more advanced with it grow my skill
Would a modified toaster oven using quartz heating elements/rods make a suitable pre heater? Maybe 2 or 3 elements, sufficient space, controls...for pre heating as laptop m/b? Thanks does using thicker aluminum foil help with heat deflection? Where do you place the lower or bottom heat sensor?
Yes you can use quartz ir, you could use thicker foil but simple kitchen foil works just fine, you only creating temperature difference enough to prevent solder melting under the foil. Lower heater sensor goes in the Center of the pcb, right under the chip you desoldering.
i was expecting to see you tweeze the balls one by one lol... may have to come to it for me. i can't afford such a machine or even the service ($90+) for swapping a bios chip on a hard drive.. (sadly it wasn't an 8 pin IC, it is built into the bga chip). do you suppose tweezing solder balls is possible and then just using a heat gun?
Yes of course it is, it’s a very time consuming process but it’s doable, just take your time doing it, like jigsaw puzzle, don’t expect it to be done in 5 minutes, don’t rush and take your time, specially with soldering using heat gun, take your time heating everything slowly.
Using solder balls you’ll have even amount of solder over the pins, using paste you’ll have a big pool of liquid during flux warm process and some pins will have giant amounts of solder and some won’t have enough, everything will be uneven.
It looks scary but grab couple of old boards and give it a bit of practice, it’s not that difficult once you try, and I have a video on how to build a BGA machine, you can just use a halogen flood lights as a top and bottom heater. Don’t give up. If other people can do it, you can do it too.
@@MaxELECTRONICS Ha yeah, it's not so much scary, as it's not worth the hassle. An old free laptop I picked up could get some more performance, but the time and money put into it would be more effectively applied to a new computer. The laptop is more than 10 years old, and wasn't designed with upgrading in mind. It doesn't even take more than 8GB of RAM total. I really do appreciate your optimism though. If I ever had to reball a board, I know where to look for info. Thanks man.
First time I have a chip which is oxidized and pads on it are darker. I can re-ball the chips, but don't know how to clear pads on this one so that my 0.5mm solder balls can hold. Any advice?
seems like ancient technique ??? I seen the mask being used and then solder paste being pushed/ smeared onto it. "done" but what do i know :) nice vid.
If it’s a fresh ball that is dull then simply add a drop of flux and reheat it, if it’s an old solder joint you’d have to remove the solder, clean the pad and apply new ball.
If you looking for temporary fix you can just flood the chip with rma flux and without removing the chip just go through the reflow process, but it’s only a temporary fix
@@MaxELECTRONICS It is an unsoldered BGA on faulty SONY TV. Even after cleanup or used desoldering braid, I still have dull pins. I still not tried to put balls on it before asking how to have shiny pins
Go over it with RA type flux and just standard solder, (as if you were to prepare to solder wire to it) after that clean all fresh solder you added with solder wick again
I recommend the MG chemicals flux, its liquid, and it’s the best, it’s expensive but it worth every sent of it. It will even make corroded wires solder together! (Not that you should do that but it just shows how good it is.)
Hi Can i run both heaters by one PID controller(and of course by one temp. sensor) ? Is the temperature of both heaters the same ? I have PID controller made using arduino and a circuit board with triac on it and the program that i'm using controls one heating elemt only.
Hi, no. You need to have a preheating and soldering element. The preheating is set to a steady temperature and stays same throughout the whole process while the head element follows the reflow profile temperatures you have to have 2 separate heaters, you can build them using a halogen flood lights. Have a look for “DIY BGA Station” video on my Chanel where I explain all this.
@@MaxELECTRONICS thanks. i have a 12cm*12cm IR element for bottom heater. If it should be steady i can make a pwm controlled circuit to keep the temperature steady.
What could be the problem if my chip slipped to the top-right corner of its site when re-soldering it to the board, instead of staying centered and snapping in place on its own ??? :|
Try using less flux and longer “flux activation” time in profile settings. Make sure all the balls soldered well to the chip and cleaned well before soldering chip to the board, make sure the board is flat and levelled and chip is sitting flat and not rocking, also make sure that before you solder the chip to board, all contact pads on the board are free of solder and flat and clean.
Hi bro. How are you. My gpu 3060 ti. Issue. Yellow tick in device manger. One Tec : say reballing going fix. One Tec : say need replace vram and module. But very expensive. What is exact issue. Bro. ❤
I have for 2 years but it’s an improper tool for bga reballing it takes forever to preheat the board with it and maintain correct temperatures and profiles, plus it may cause damage to the ic or textoite, that’s exactly why I’ve build BGA station.
@@MaxELECTRONICS For someone who just wants to do 1 bga job every few years and enjoys the hack farmer jobs I'd be interested to know how people fine tune the handheld way. Which technique did you use. Perhaps you could do a video and show how frustrating that method is but how it can be successful with low rates.
You asking me to build a chemistry lab with a garden hose and a bucket. You need the right tools to do bga, not just hot air gun. You wouldn’t use a piece of wire heated by the candle to do soldering would you? I mean it’s possible but you can imagine the result. You need to have preheating for bga no matter what you do.
If you enjoy working with incorrect tools please do, I have nothing against your choices, each to their own, you prefer hot air gun, I prefer BGA machine. Let’s just enjoy the tools we prefer to use
It’s actually home made gear, you need those tools to do bga, can’t do without them. I have a video on how I built the station and how you can do it too, from low budget to high.
@@MaxELECTRONICS i konw it but homemade for me " u can do somethings with what u have at home " . if i buy somethings and build at home , ita not homemade for me. maybe bga with hot air and flux and some basic tools meaning homemade. Anyway good work even not homemadenfor me but good.
I was expecting a reball with tools found at normal home like a heatgun etc, i mean title implies reball at home. This is a professional setup, maybe a semi pro, pretty misleading title. But thanks for the effort and video anyways.
You have to use the reballing machine, you can’t use heat gun for reballing, there’s a very high chance that you will damage the chip, this is a home build reballing machine.
@@MaxELECTRONICS that i understand. larger chips need bga machines or it could cause damage, unlike reballing a 2x2cm or 3x3cm chip which can be done with a hot air station. I just said the title is misleading, this machine maybe built by you at home but it is a semi pro level DIY bga machine and requires significant investment both in time and money. When a title says 'reball at Home' one would expect a much simpler setup. Anyways. Bye
I did describe how to build budget reballing machine using 500w halogen flood lights. You have to use proper tools for the task, even small IC’s need preheating, flux activation period ect.
This is a home built machine, I didn’t buy it, there’s a video on my channel on how to make it, and you could use normal flood lights instead of heater and preheater head

@@MaxELECTRONICS But the stencil should allow you to spread the paste evenly, shouldn't it?
Yes but when you heat it up it will become liquid and turn into one big pool of liquid because of the flux on the paste. It will not hold shape.

No, always cleans up really well.
@@MaxELECTRONICS why not 99% ipa?
Just personal preference. Thinner is stronger then IPA
when everything on the board are heated up to 200+ degree do you have ANY idea what will cause one slight movement of the tape or the aluminium ?
Thermal expansion?
The slightest move of the tape you used or of the foil because of the hot air will swipe everything on the board all tiny capacitors etc
That’s why you have to wait for cooling period to finish before touching anything
Plus the foil is there to protect other parts from heat.

@@MaxELECTRONICS the cavemen did it. I love the hack jobs. Anybody can get a job done with the right tools. The art is in the bodgy.
If you enjoy working with incorrect tools please do, I have nothing against your choices, each to their own, you prefer hot air gun, I prefer BGA machine. Let’s just enjoy the tools we prefer to use
Im so sorry :)) its so funny to me
The title: Reballing at home
First 6 minutes is my dude pulling up an industrial infrared (?) heater. KEK!
cool !!
are you using leaded solder balls? If yes, 300c is too high.
300 is an element temperature
What about temperature on fan? I missed it 😾
The fan is there just to speed up cooling process, it should be turned on after soldering profile is completed.
How much temperature 21:29
360
Celsius
Name of that device?
at Home?
maybe the fly is also soldered to paper
...is 300 c or f ??????????
C
Very neat, but almost certainly *not* an "at-home" type process. This is all very expensive professional gear, not apt to be found in a small shop.
It’s actually home made gear, you need those tools to do bga, can’t do without them. I have a video on how I built the station and how you can do it too, from low budget to high.
Fives warned us about the chips....
bro, u are insane.. describe clearly
why did you Reballing ?
Because it had dried out solder joints that I saw on x-ray.
@@MaxELECTRONICS will it solve no display output in my home theater
You have to diagnose the fault, it could be something as simple as broken pins on connector or bad voltage busses or something else.
is this at home? just funny video
Yep that’s at home, with home build machine. You can build your own, here’s video how: th-cam.com/video/CqqU1jwzgqw/w-d-xo.html
@@MaxELECTRONICS i konw it but homemade for me " u can do somethings with what u have at home " . if i buy somethings and build at home , ita not homemade for me. maybe bga with hot air and flux and some basic tools meaning homemade. Anyway good work even not homemadenfor me but good.

Well that was unexpected-

Cockroach infestation th-cam.com/video/cTfuaNqfPKI/w-d-xo.html? I guess he will have his boards bugged :-P
I think he said “there’s an ant there” 😆
Did you see that cockroches😆 crawling?
"at home" - equipment costs vs. device costs
The equipment is also home made, you can checkout the video on how to build a cheap bga station, you can use simple halogen flood lights as heaters.
I was expecting a reball with tools found at normal home like a heatgun etc, i mean title implies reball at home. This is a professional setup, maybe a semi pro, pretty misleading title. But thanks for the effort and video anyways.
You have to use the reballing machine, you can’t use heat gun for reballing, there’s a very high chance that you will damage the chip, this is a home build reballing machine.
@@MaxELECTRONICS that i understand. larger chips need bga machines or it could cause damage, unlike reballing a 2x2cm or 3x3cm chip which can be done with a hot air station. I just said the title is misleading, this machine maybe built by you at home but it is a semi pro level DIY bga machine and requires significant investment both in time and money. When a title says 'reball at Home' one would expect a much simpler setup. Anyways. Bye
I did describe how to build budget reballing machine using 500w halogen flood lights. You have to use proper tools for the task, even small IC’s need preheating, flux activation period ect.
not play this at home. all tools commercial use.
I’ve build all tools myself, it’s not a bought equipment, it’s diy. And you need it to do BGA properly
don't understand the title of the home rebaling clip, so 99 percent of people don't have this machine at home.
This is a home built machine, I didn’t buy it, there’s a video on my channel on how to make it, and you could use normal flood lights instead of heater and preheater head
