The USB trick is neat but do not ever use paste like this. This creates tiny beads of solder balls underneath BTCs like these and adjacent components that can cause shorts if they were to ever come loose or even on initial start up. I have plenty of x-ray images of assembled boards that failed as a result of improper cleaning of solder paste on a failed print. Though the cause is slightly different, the result is the same. When using solder paste for BTCs of any kind, apply the paste to the individual pads and do not add additional flux as it's completely unnecessary and can cause the mix to activate improperly. When using hot air, it's quite easy to get the flux in the paste to become quite "runny" also potentially causing the same issue. It's best to heat paste slowly to prevent this. You may have done hundreds or even thousands of repairs like this, but it only takes 1 to ruin someone's day or worse.
@@dannefan_senshi perhaps a couple times. Lol. I work in a facility programming machines that do this kind of work automatically. But I also do rework and minimal electrical designs myself as well. Helps to know all sides of the trade.
@@robertheintz8017 Surface tension keeps it in place unless you lift it or accidently bump it. It's always best to practice over and over again with junk boards and hot air to get use to lifting, moving and resoldering until you get the hang of it. Also flux is your friend, the more the better...
@robertheintz8017 for the most part, they do, however each individual component is REALLY light, and liquid solder has some surface tension to it that the component's metal pads stick to. You can actually see this when the new component is soldered back down, as soon as the solder paste melts, the component melts, the component shifts slightly to align its pads to the boards pads. If you use the correct amount of paste (which the guy in the video almost rarely ever does) then the chip will almost perfectly align itself (granted it started close enough aligned already)
This is *not* the way to do SMD rework. Using solder paste in this situation, without a stwncil, AND THEN going in with a soldering iron is possibly the worst way to go about this. Just leaving the original solder in place wouldve been better than this. Wicking and adding more solder using solder wire would have been best.

I watched the video several times in magnification, especially the part during and after attaching the chip. Because when I first saw the video I thought that there must be extra solder all around. Yes, the circuit board and the tracks on the circuit board are protected. But of course the SMD pads are not. Otherwise it would be difficult to solder anything on. And despite the fact that they are working with hot air, which doesn't seem to be particularly precise, I didn't see anything that would indicate any additional solder on the pads. I'm really fascinated! Yes, air is a good conductor, which is why the side winds (I'll just call them that) of the air flow cool down quickly and don't reach the necessary heat for the solder to connect somewhere other than where it should. I'm really "blown away" by it! Soldering is really cool! Good job by the way! 👍
I build electric guitars and im meticulous about solder and precision joints and this just blows my mind lol i would think a circuit board would be much more fragile
Ive been soldering various piping systems for 23 years and i know nothing about circuitry so using copper wire as a sponge for molten solder may be a typical technique, but to me its friggin magical
Solder wick is braided and made specifically to remove solder. I have always marveled at how well it works...the more flux the better. Not sure about using those solder beads, seems extreme...I'd just add a little solder to the pads and solder it down

There's no reason to have those solder spheres rolling around in the case you missed them on cleanup. Most people watching don't realize the skill lever for even this chip replacement.
This flux will stay under the chip and corrode the connection. No good! Dont soak it in flux like that! Better to just ramp up and cool down the rework temperature to melt the solder properly with minimal flux use.
That's a lotta paste and flux, but also looks like there's conformal coating, so might be fine. But get a needle dispenser for both and you can cut that out.
I never repaired electronics like that. You just don’t need that much flux and you don’t let the solder just flow all over the board. Now you’re going to spend time figuring out where it’s shorted elsewhere. And replacing additional components. If you keep doing this laziness you’ll never actually fix the problem. Is using a soldering iron really that difficult??
My god I hate that solder wick braid stuff it always takes me about an hour to get all the solder off. The last time I needed to solder a wire to a PCB as the negative battery cable had pulled. I spent ages trying to get enough solder wicked off the pcb so I could stick a new wire thru the hole, and this is a tiny pcb probably about 1" square. In the end I had the genius idea of just using a really fine drill bit to clean the hole up, which worked a treat.
You didn't actually need to remove the flash. You can upload UEFI firmware by connecting an external programmer to the connector on the side of the flash, which you covered with a metal piece. If there is no fault in the flash chip, there is no need to bother removing it.
Can you link the solder and flux you’re using here, and the air and iron temps you used? It all seemed to run exceptionally well and turned out better than my last few repairs 😅

I see alot of people using this solder paste...I hate using that stuff, it makes such an unnecessary mess most of the time...I guess as long as you clean really well it doesn't make a difference, but I have never had issues just using a roll of solder wire to put a bit of solder on my iron tip
Congratulations!! if you know how to do this stuff. When I try I burn and things don't look pretty. 99% of it I don't understand. Normally replace circuit board and not worry about it
Do people in factories for every board made put all the hardware onto the boards like this? I would imagine high tech machines do it to meet production deadlines.
Too extra on this. Too much heat vs time and the thermal shock of the alcohol on the surrounding hot SMD parts like that ttransistor and regulators. Reducing chip life. Clean the pads and use wire solder instead of solder paste. Too much of a mess to clean up after. I cant spend a lot of time on a repair like that. I have too much work to do anything that slows me down. If you hear hissing when alcohol is applied or it boils off, its too hot. Yes it may work fine but reduced chip life
I will never understand why you guys use solder paste. I mean, it gets the job done but I could do it much faster with a lot less clean up with 63/37 leaded solder. And the biggest part about it is you don't have to worry about a solder ball getting between two tiny components and creating a short.
What a terrible way to use solder paste. Pieces of solder are everywhere now. Use it with a stencil when reballing a chip, cleaning up the excess away from the board you're working on.
The copper mesh is supposed to stay on the spool, you cut off what is used and bad AFTER USING IT because keeping it on there removes almost nothing, as you have to wait till you grab another tool to take it off, where I just saw so much nasty shit just go right back in… not sending you my shit
what is that glittering thing that seems to be used to clean and weld in the same time. Same for that gel...used before and after.. You heat it, it come out, you heat it again, it stick... wtf...
Makes it look easy doesn't he folks. Remember not to burn a land, or loosen those resistors right next door. Oh yeah, by the way, he's working under a microscope.

Tak nie stosujemy pasty lutowniczej, bo jest dużo czyszczenia potem. Zobacz jak ziarenka litowia się rozlazły. Ale pomysł dobry.❤
Can you make a video of explaining each process you did ?
Why do ppl push down on these chips. The excess solder on the bottom would make contact with the other traces when it's pressed out, wouldn't it?
I know these vids are extremely zoomed in, but I still feel it's too much flux
Too extra on this. Too much heat vs time and the thermal shock of the alcohol on the surrounding hot SMD parts like that ttransistor and regulators. Reducing chip life. Clean the pads and use wire solder instead of solder paste. Too much of a mess to clean up after. I cant spend a lot of time on a repair like that. I have too much work to do anything that slows me down. If you hear hissing when alcohol is applied or it boils off, its too hot. Yes it may work fine but reduced chip life
I will never understand why you guys use solder paste. I mean, it gets the job done but I could do it much faster with a lot less clean up with 63/37 leaded solder. And the biggest part about it is you don't have to worry about a solder ball getting between two tiny components and creating a short.
What a terrible way to use solder paste. Pieces of solder are everywhere now. Use it with a stencil when reballing a chip, cleaning up the excess away from the board you're working on.
SMD repair is so satisfying to watch. Especially since I suck at it, lol.
😂....yeah man, same here!
I can teach y'all how to perfectly fuck it up, step by step....(every step)
@@aazraelsnachtschicht LOL!
I would not trust all that excess solder floating around. Adds to cleanup time and if you miss anything it could cause shorts later on.
How are those small components still holding? Do you have a nozzle to direct the hot air? Thanks
I feel like I just watched something primitive yet advanced at the same time
The broken USB cover as a shield... genius !!!
oh the joy of having equipment that works well
This is beautiful 👾 this is therapy for me to watch
The copper mesh is supposed to stay on the spool, you cut off what is used and bad AFTER USING IT because keeping it on there removes almost nothing, as you have to wait till you grab another tool to take it off, where I just saw so much nasty shit just go right back in… not sending you my shit
I like how the copper wire absorbed the old solder
PC repair - Do you want some motherboard with your flux?
Customer- fuck no, more flux
I never use solder paste in those situations! It is bad practice.... also too much flux!
Impressive what can be done with the right tools and method.
The solder paste is all over the place. Not recommended practice.
what is that glittering thing that seems to be used to clean and weld in the same time.
Same for that gel...used before and after..
You heat it, it come out, you heat it again, it stick... wtf...
Bga soldering flux, low melt solder paste 183c or 138c, IPA 99 for cleaning
So you have to be sure that the new chip will remain unburned (undamaged) after the soldering process..
This is the worst thing someone can do , leaving solder balls flowing like a river around
I swear the extra flux is used on purpose just to get us all to engage more in the comments
Weekly at work on average, 0402 are big, bga/leadless normal
Masha Allah may Allah give you succes in your business.
Wow MXIC the company when im working for 16 years 🎉❤
Him: years of hard work and knowledge
Me: ahh yes more gloopy
Makes it look easy doesn't he folks.
Remember not to burn a land, or loosen those resistors right next door.
Oh yeah, by the way, he's working under a microscope.
My luck: the flux would have allowed a solder bb to stick the usb shell to those "pico-sized" components 🤭
Boss: why my accessories cost is more then the repair cost of earning 😂😂😂
This man has never heard of FOD before.
@@Raccount100 what is FOD 😮😮😮😮😮
Electronics Alchemy. So satisfying. 😊
And then I melt every component on the board, but the solder is still perfectly solid.
This is so hard to watch. Lack of concave fillet, uneven solder application, dirty workpiece, wicking took out solder to other SMDs, where to begin...
Great ! What kind of paste do you use ?
What flux is used? Tell please
It looks great
The swan looked like it contaminated more than cleaned 😂
