BGA Chip Reballing (without a stencil)

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.

what ball size do I need for iphone repair?

How if we heat the ic from the bottom

long time

Please tell me what is your flux name😬😬

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

Wonderful how did u make balls
Please show me

good try

Best patience 💪 wow
Exchange visit😜wow y2y 😜

Amazing work

Not very practical for high pin counts.

Good job 👍

Solder balls size also 0.8mm?

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

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

Your eyes CCD camera placement die bonding machine 👍

You are one crazy ....

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

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

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

have you tried 3d printing stencils?

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

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

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

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!

Nice job Livyu!

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

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.

nice job man

I'm speechless, that was awesome !

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.

Really well done!

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

Nice Job!

Mesmerizing.

Oh been there, done that

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 🙃

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

I am gonna have a punt on shark byte lol

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

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