•An easy to understand method of removing an IC Chip from a stencil once the Job is done.
•Tips on making sure your IC chip is in PERFECT alignment with VISUALS.
Clenaning iron before putting it to stand will significantly reduce tip lifespan. Rather leave it dirty and clean before next soldering or tin it before putting it to rest. It looks nicer, yep, but clean iron will expose metal alloy and it will oxidate quite fast. Great balls though, it is hands download best reball guide.
Clean it and tin it is fine then you have to repeat that before soldering
Really great overview, Justin! Thanks for the clear explanation.
Thank you Kyle! Glad to get support from the Teardown and Guide master of the Repairiverse! IFIXIT!
Thank you, this is great stuff. Really building my confidence watching these, can't wait until I get home
You've just made me stop procrastinating reballing an SMC. Just fixed an old 820-3462 board that has been sitting on my desk for a while... haha
Thanks for the motivation and the good tips.
Thanks, Justin. I love tweezers and really don't know how many that I have. I love the bent tip tweezers the most. Some of my favorite tweezers are vintage Dumont Dumoxel tweezers.
So many! But... SO MANY MORE TO BUY! hahah am i right =D I cant stop myself, Always trying to find new uses for the ones i have too.
@@TheArtofRepair Yep, I'm always looking for new tweezers.
Thank you very much about this video.
Thank you Justin. amazing information as usual.
Please which type of smd rework station is good for ic reballing
Helica or vertical type
Can you recommend any european location that can do reballing of NVME memory controllers?
What is that mesh surface he has the ic? With the mat i use, the silucon rubber lifts up due to the heat
i just can’t explain how much happy i’m right now
i’ve been looking for this for long
now one explains this better and no one in my area will teach you too bad
That means we are together on this. I've been searching this too for days now. I was like "that's what I'm talking about!"
I apologize for the late reply, 6 months late actually, I have just been out in the wild doing repair things and not focused on youtube. Im glad this video helped you =) Hope to see you in the comments section again =)
beautiful work Justin ! if possible make a video over taking some important reading/measurements on a dead board please? Thank you
thanks for the video. i have universal stencl but i only can reball emmc and some other ic. but still i cant reball cpu and power ic may be because i don't have microscope or stencil not fit for all ic
Hi Justin! Did all the steps you told, and my reballs are getting perfect. The only hard time I'm founding is with bigger chips, like PMIC's, EMMC's and CPU's from Samsung, Motorola, etc., and it`s worst and they have some "empty" balls and I do not have the correct stencil for them.
Is there any trick to help with this? I'm using a small piece of glass to help out, its working, but it tooks too many tries to get things to work :(
Thanks for the excellent video as always!
Hi, thanks for the video. It was very good tip, when you said to apply flux and 140C to lubricate the stencil. Now the balls didn't get stuck like they used to before using this tip. It took only 10 min to reball IC. (steps: Clean IC pads with wick, apply stencil, apply balls, heat 370C from corner angle, apply flux, heat to 140C, remove stencil, apply heat 370 to get balls self align.)
Heck ya! Glad to hear it worked well for you 💪💪💪
Just curious as to why you do not clean the old solder from the chip with wick after you run the ball of leaded solder across all the pads? Maybe it’s because of the style of tip you are using on your iron ?
useful video brother. thanks for sharing your guide....
can u tell best bitmap software for samsung and other android phone ?
Just stumbled on this video and 1st time watching you. I have been searching if it's possible to reball with the simple tools i have & I've seen very clearly that i can.
Subscribed without waste of time.
Heck ya! Very glad to see you join the channel! A lot of new videos made in the last year that are on the way! Pay attention in September/Nov!
@@TheArtofRepair Ok. I'm tuned in.
I like your setup with the greenscreen behind you, and your setup visible, and not just your head... nice!
Thank you Justin.
Thanks for teaching
Your intro was superb. It hooked me up!
Yay! Thank you!
This is a gem!!!!
What do you recommend to do when the stencil lift itself up while pressing with the tweezers on the edge of the array?!
Not all the time this is happening, however with larger ICs, that tends to happen often.
Once that happens, the paste/balls will merge in the center where the stencil is lifted the most.
Just put tweezers across balls, apply pressure directly to the chip. its gonna be fine, trust me.
Thank you for this video, sir. I had fun reballing watching your vid.
Yay! I’m glad to hear that you were able to learn from my video :) I hope to see you in the comments section of other videos in the future 😀
Is it possible to reball without the appropriate stencil like if i found a stencil with the same ball arrangements can i use them?
Yes
16:18 it's me
Who is thinking same..
Why a historical video is playing!
Did I pressed next button!
haha yes! XD best to watch it all for the full effect =D
Good learning bro.congrats.god bless u.
Thank you Justin! I am a total microsoldering noob coming from screen refurbishing because of the touch ic . Please do jumpers next !
Jumpers! This would be such a good idea to do on its own! Ill put it on the whiteboard right now!
How long are those grand pappy tweezers he’s talking about?
Thanks Justin! Great video as usual
My pleasure! I appreciate you commenting and watching! Hope you learned something today =D
Great explanation
I'm using a aoyue 968a+, what I can afford now is it a problem when reballing chips and removing components
great job! thank you!
Thank you, I will use your techniques next time that I attempt to jailbreak my nintendo switch
I dont even have to reball anything and I found this interesting
Thank you so much.
Awesome really helpfull Thanks!!
great job
Thank you sor
How to temove pested (black white pested IC )
Thank you so much Justin, I’ve always had reballing issues , it gets stuck etc. But the flux and low heat nails it !!!!!
Great to hear! I know that sticky chip thing freaks people out!
Where did you buy those tweezers, any link?

Very good video. Congrats.
Great video
Thank you bro
great video. I really feel comfortable giving it a shot. As you know I don't really do phone so I am outsider on this but any suggestions on boards I could grab off ebay for cheap to practice on? something that they still sell stencils for? It doesn't have to be fixable just something to practice technique. If you want to sell me a bag of parts/boards I'd be happy buy especially if you had a stencil to go with the stuff.
Just get iphone 4 with stencils, 20 bucks for working phones and stencils are like 3-4 bucks for basics.
I've found a large stencel kit on eBay, something like 100pcs for cheap, came with 4 different leaded ball sizes. Many of them are universal, can do anything from TV arm MCU, consoles, ram. I used one for a Chrysler radio gpu chip and LG tv main board.
@@jeffescortlx I see you have found me haha.
@@FixedUntilBroken yep I like Justin's videos, especially re-balling. He makes the process look easy when it typically ends in fits of rage for the average techinition.
@@jeffescortlx same. I've I'm here trying to learn some mobile electronics to make me a little more well rounded. Not looking to do mobile electronics as a business but I see more of out automotive electronics getting BGAs and Screens on them. I feel like one day automotive electronics and mobile electronics are going be very similar.
Is the Cleanroom cloth Kimwipes or something else?
They are available under cleaning supplies on Shop.Artof.Repair, but they are just basic microfiber cleanroom cloth, the same used in the factories in china every day. Thats why i started calling them that haha. Lint free n such =)
where is the best place to get the solder tensile??
Yea, just happens to be my personality. It’s the price we pay for when something is free 🤷♂️
Do the AOR-V-004 tweezers magnetize?
Yes, they are made of 304 steel.
@@TheArtofRepair Thanks. Do you sell similar that don't magnetize?
Keep it up Justin! Not all can do the hot air thing. Phone guys and smders can. It as on the list. Kinda picky about tools, you know! Real good video. Stay safe mates!😊👍🏻😷
Well the good news is, the next method does not require the hot air at all you’ll see that method debut in 102 I’m pretty sure it’s kind of unique
Thanks bro
@9:30 Whachya doin' down there, buddy? hahahaa
youre amazing man
Man, I miss having my shop and doing this work.
Theres always side hustle work!
What I'd like to understand is how you obtain the info from manufacturers for forming the profiles for reballing. Cameras which although might not be necessary, are beneficial when magnifying the chips during reball. How about using various laptop motherboards to reball cpu and graphics chips.
thanks!
great video!
Glad you enjoyed it Hope to see you in the comments again sometime!
@@TheArtofRepair would love to see if you can do a video on lots of scopes that come from china and india and do a shoot out. Would love to find a scope one day that is very good yet very affordable
@@davidvalens3337 Scopes are easy bro 💪
Just depends on your budget
I can probably throw together some videos on picking a microscope would that work?
@@TheArtofRepair would love any videos but it would be awesome to see a comparison video and also a video on how to identify bad scopes. Or scopes that are not with buying
magic!
Keep going bro
Have you taken any PACE courses ? Industry standard stuff ?
Inspirational sure, there videos are second to none. But formally no. Iv had a few soldering mentors over the years including a few IPC guys.
Thanks for the question! I appreciate you taking the time to watch my video :) I hope it helped 💪
Hello Mr justin ....why is the chip removal temperature always higher from the temperature used to remount the chip back on the board after a reball...
Original balls are lead free and have a higher melting point.
Because the solder holding the chip on the board originally is lead free, and lead free solder melts at a higher temperature. He replaces it with a leaded alloy that has a lower melting point
I love this video
And I love this comment! Appreciate you passing through. Hope the video helped :D
ficou top meu amigo
Your reball method is great my only issue is your stencil, I would prefer a stencil with square holes not circular ones also I try to use cue tips instead of a cloth but that is just personal preference.
Same on the q-tips, I work on these almost every day!
Thanks♥️♥️♥️♥️
extremely Nice wrk
Hello sir..my speaker and microphone always good...but not working on INCOMING,out going calls..and also not working VOICE RECORDER permenently
( I am also changed Cc board and mic..but still have this problem....what is problem...plz tell me the issue..I hope replay this comment)
I hope you replay this comment and solve my problem..thanks
Model name :- REALME C20 / 2GB RAM
So nic working 👍
I don't have a problem with reballing. But I do have problem when the chip pads are oxidised and the balls don't like to hold to them. What's your advice on that? :)
Normally I don’t recommend smaller tips but maybe a smaller J tip with some solder on it and the pad has some flux. It would also help if the entire chip was at a decent temp. So if you could use a ic jig to hold it you could heat it up with the hot air and see if that will break down the oxidation.
I know the problem your having and it’s a common problem
Remember flux is a detergent and a barrier so that plus the right amount of heat and solder should do the trick. Let me know how it goes!
@@TheArtofRepair thank you. Might try to record it and observe the outcome. If will be worth sharing, will post in on my business YT and comment here.
If not, at least will comment what I did :).
Great succes👌
15:52 hahahhaha OMG that was so funny!!!!
haha im glad you caught that. =D
Hey Teacher (I hope you don't mind me calling you that).
I'm sorry but I've tried every single hint you shared in the video. By the way, thanks a lot for sharing. You rock!
But unfortunately, there's ONE CHIP, or THE chip that literally just laughs at me every time I try something different: CYW4356XKUBG or BCM4356XKUBG, it's a Wi-fi/BT chip for the Nintendo Switch. I spread 63-37 solder with my soldering iron, remove the flux using a cloth. Then, I proceed to line my stencil (similar as yours) up with the chip, apply solder paste, hot air @350ºC with very low air speed. I struggle a little with indirect heat (even after following your steps), but eventually all the balls are formed, oh and all of that while still applying pressure around the chip with my stencil. And I end up with 2 or 3 bridges on the chip.
I've also tried gluing the chip with the stencil using a tape behind the chip; Same result;
I've tried leaving some flux on the chip because a friend of mine told me some balls might not be forming or staying on its spot because of the lack of flux; No, still same result. Although it was only one bridge, but it involved six or seven balls;
I've tried changing the air temp to 365ºC and going up the air speed a little, but it rendered the ugliest result;
Maybe something is wrong with my solder paste, which is a Mechanic one. 63-37, melts @183.. I dunno.
I even tried changing from a steel spatula to a thermal paste spreader (I don't have a plastic spudger), but results didn't change.
I'd love to watch you try your luck with it. Maybe it's just not meant to be reballed?
Thanks again for the vid and I'm sorry I'm 2 years late for this. It took me a while to find your vid. Keep up the great work (:
Email me a video justin@artof.repair and I’ll see if your missing something.
today tried reballing baseband
10 tries 10 failures
points missing and poping out
Is cleaning the chip off with copper wick before reballing pointless? I have always done it but I see you don't
I always use wick too
It would remove any oxidation on the pads ensuring a good connection (if that was the cause of the fault). Downside is it takes time and there is a risk of removing pads.
Mixing lead-free and leaded solder... Would lower the melting point and add lead to the alloy. I don't think it is a huge issue, especially if longevity isn't an issue.
Would love to hear Justins opinion on this though
This will be answered in next Monday's pre video livestream in more depth, but in short, If we are realloying with 63/37 which is 183, then applying the same as paste nothing else should be effected. Cleaning the BGA array flat IC side is pointless in our microsoldering context. cleaning the bare board with wic. yes, always, but yal know how i feel about that haha.
@@TheArtofRepair " If we are realloying with 63/37 which is 183, then applying the same as paste nothing else should be effected."
Since RoHS directive, everything should be lead-free, including the BGA's (Imagine the horrors in production if only a few areas has to bee leaded and others lead-free)
Lead-free is often SnAgCu alloys, so adding a bit of SnPb will 'only' add Pb to the alloy, though not in the normal 63/37 percent ratio.
My view on this is: Know what you're dealing with, clean it up if in doubt - always do it correctly (even though it takes a bit of time - it will save you time in the long run)
I figured the reason you want to reflow after stenciling the balls on is so you can flood it with flux and ensure the balls are properly bonded to the pads.
although it’s very very rare for that to happen yes that’s one of the reasons. The main reason being just to line everything up so that as you offset it with the pcb array it will grab properly across the array in unison 😎
I am a new beginner in IC level work i had started IC level work from last 4 days and i didn't understand what i am doing i messed up
I watched your this video and i am really excited to work step by setp as u teached.
THANKU 😊 JUSTIN BHAI 🙏
Bro,I did same
But my stencil as I put my blower near to it
The middle portion of it expands like a balloon and the contact with Emmc breaks
Is it a bad stencil!?
To much air and heat. Why not start right at solder melting point and find a good point you like with low speed.
Don’t blame the stencil, my favorite stencils are the cheapest :) lol
@@TheArtofRepair ok dude,let me try this and get back to you
Boom
He knows! Coming in hot!
Can I have lessons please

LFG!!!
Hello sir from India Telangana NALGONDA
I know you where trying to eliminate all excuses,but my puppy ate my stencils.
Weird enough I bet there sum puppies out there that would get a kick out of crunching a stencil. This almost passes… 😅 almost…
Haha good try! 😂
@@TheArtofRepair im going to try this, thanks. I have always used balls, but with practice I suppose😊
subs..clicked
It’s impossible to reball. When I do it, 10% of the balls solder to the stencil. Reballing is stressful. I exactly did what you did.
You might need to step back and revaluate your situation tools and consumables to make sure they are all good. As this technique does work. Maybe you can make a video to share with me so i can see where you are going wrong?
Please bro reball nand ic
i dont have the money to join..but soon sir.
Where is 102?
واقعا خیلی عالی هستی اما زیاد حرف میزنی!😌😌
Why all you guys put that sponges on the wall? I've seen it on many labs and dont get it why you need those soundproof sponges on the wall.
Its for sound absorbing to reduce echo and outside noise =)
Your logo is just begging to look like the Southern Comfort bottle logo. Was that your intent?
Too much corny personality and time waste.... "Gee I'm cute" pushing. Boring!
Пинцетом чип держать не надо ты его будешь колоть, делов на 1 минуту, а тут ролик 25, тля кого вы это записываете?
I think without hearing what I'm saying and why I'm saying it in your native language the video context might be a bit lost, which might be why you feel that way. Hopefully one day my videos will be in many languages. Thanks for your view! Hope to see you in more comments.
.......talk toooooooooooooooo much.
Well, at least you can reball now. Maybe play the video at 2x? 😎
Far too much waffle for my liking
I have no idea what waffle is 🤷♂️
Sir what's up number
