Beautiful work Livyu! I had a horrible day at work, was super stressed and then I watched this and somehow all my stress and worries melted away. Thank you for a moment of instant zen!

Precision of a deity - even after 6 years of practice I still can’t clean up as nicely as you - your reworking is absolutely insane 🙃

I've tried this very same thing before and came out as f***ing disaster that took WAY to long to do. He made it look easy. I almost suffered an aneurism in the process.

You gave me the confidence to repair a USB port. Works great! Now to replace the USB port that got ripped from my flight controller.

Great work. Thank you

WOW!!! Thats is trully amazing!!! And always 1 last ball is out of the line! ;)))

With H7 BGA chips coming. I think it's time I learn this too. Great Work !

Mesmerizing.

I'm speechless, that was awesome !

I don't know what that is, but you always grab my attention!!!

Nice! Have you tried a soldering skillet/soldering plate? They’re great mostly for initial builds, but in situations like this they’re awesome too

A mi parecer está bien si no hay el stencil pero sería mejor con una plancha con la que quitas y pones led y más seguro que no se vuelan la bolitas con la pistola de aire

I like to use this technique but I use a pipette , poor on the solder balls, and separate them with a probe needle. light flux, 250 reflow.

6:35-6:45... That’s some crazy visual ASMR man 🤣🤣🤣

Really well done!

Amazing work

a lot of people who are into FPV also get into electronics repair and vice versa. It's cool

Thank you so much for this method. Unfortunately, this method is quite time consuming especially if the BGA IC chip is a 153 that I'm trying to solder on properly and onto the board. It's also going to be even more time consuming if you aren't using a quality flux; cheap flux will not help you with this method unless you do research on their effectiveness. I'm using SRA flux #135. It's a great flux that can easily flow the solder balls even at the lowest Air speed with a relative temperature of at least 350 °C. Just confirming that a quality flux will make the job easier for this method on your behalf. I tried a different method by flooding the whole IC with flux in liquid form AFTER putting all of solder balls on. In my practice, you can move the solder balls by periodically heating the IC and the flux; this way you won't lose any solder balls unless tension from the tweezers are being heated where the solder balls can climb up on the edges of the tweezers. You need to keep the tweezers as close as you can to the IC where the flux is being heated where you have a low chance of loosing them in between the tweezers; if so, you just need to clean the tweezers and grab a new solder ball.

Nice job Livyu!

How if we heat the ic from the bottom

nice job man

how many mm solder ball did you use? and what is the air and temperature setting?

Good job 👍

Nice Job!

what ball size do I need for iphone repair?

I think can follow your steps with small chip but with larg chip, so need more more time to complete process. Good job

Please tell me what is your flux name😬😬

Its very slow if you must pickup the tiny ball one by one. Instead you can spread all ball on pads and arrange it from there

very good job! What kind and size of solder balls did you use?

which PCB was that in the end? cmon, we are still waiting :)

I tried doing this on a PowerPC processor from a powerbook g4. I put ALL of the solder balls on by hand with tweezers which only took me about an hour but when I got to the end of it I started to slowly heat up the chip and on a low heat setting but the solder balls just keep coming off. Wasted my time and effort doing that 😡. And I DID apply flux before putting the solder balls on, and I spread it all around the bottom of the chip but it made no difference. I was also keeping my heat gun a big distance apart, but when I heated up the chip, the solder balls don't stick to the pads!!!! What am I doing wrong?

Hi. What do you use to clean off flux residue?

have you tried 3d printing stencils?

Solder balls size also 0.8mm?

Wow very nicely done! Did you get a P1 IC?

Your eyes CCD camera placement die bonding machine 👍

Wonderful how did u make balls Please show me

Oh been there, done that

when we dont have any service , we can try this type , for making time pass

You are one crazy ....

Well that's my OCD (obsessive compulsive disorder) fixed.

I need video how to reball without those little balls. 😀

Not very practical for high pin counts.

Do it on 450 pin ic . I am sure you will never do it again.

long time

I am gonna have a punt on shark byte lol

good try

Ribet banget 😅

Best patience 💪 wow Exchange visit😜wow y2y 😜
