I have split and hand reballed the new 15 Pro Max (eSIM model). Some interesting findings:
1. Since it's a USB Type C device, I didn't find a CD3217 chip, like we see on MacBooks or iPad Pros.
Instead, there's possibly a different chip from Texas Instruments (see pic), that could be responsible for USB charging and communication
2. This is still using the same BBPMU as iPhone 14PM. Which is all same look and feel as 12 and 13 series. So expect more broken BBPMU causing shorts after hard drops
3. There's a lot of large ground pads on the interposer. I measured them all and confirmed they're ground. Very interesting change..
4. And of course, they're still using high temp solder for the sandwich/interposer pads 😅
I can't wait for some reballing stencils and i2C T20 heat plate for this model, cuz it was a pain to hand reball 😅

If you have a Seek Thermal Cam, you're missing out if you don't have a VCC Seek Stand: https://www.vccboardrepairs.com/buy-seek-stand
Injured Gadgets just got these back in stock, so get them while you can!
It can take us a while to build these out sometimes, so they're sometimes out of stock for a while, but we're working towards always having inventory ready to build more as they sell out.
This stand makes using a thermal cam so easy. So much better than any other thermal solution on the market.
It allows you to get real close up (using my Macro Lens), and easily find where the short is coming from.
Plus it's hard free, so you can have your hands free to try to boot the device from DCPS, while having an image that is in focus & not moving around.
You can even record a video through the app, while you inject voltage into the short, so you can go back & see exactly which component was it that was heating up.
Save yourself lots of time by getting a Seek Cam, Stand & Macro Lens! ...
Anyone who is doing game console repairs, knows how many screws you need to remove to access the motherboard.
Especially the PS5, with the 5,000 screws or so.
If you don't already have an electric screwdriver, GET ONE ASAP.

🌟Extended T9 Bit: https://amzn.to/3c4YJac
It's rechargeable through micro USB and allows you to easily swap the tips out. You can also fold it to be straight or L shape.

I was surprised this one was successful...
Hope you guys enjoy all the detail I provide in the videos!
These cloths are amazing. They're soft but don't melt when you heat them.
They're perfect for reballing ICs. Just fold it in half twice & place the IC on top.
While you're reballing, the chip will sink down a bit & allow you to reball much better than if you were to reball on your workmat
