Cracked logic board, possible repair?

Hello everyone,

I wondering if it is possible to repair the logic board by soldering the two severed connections.

The phone was in my pocket during a bike accident and appears to hit a sharp rock in the back. The dent is pretty significant and destroyed the screen. After a screen replacement, I noticed the power button nor front/back cameras work. After some more investigating, found this crack on the board.

Anyone have any schematics for this part of the board? Curious if I can solder the gold connection on the back and the silver bridge connector? Anyone have any experience with this? Thanks

It's not as simple as soldering top and bottom.

There are very small traces going through the board itself, and everyone of them would need reattaching, and they are the width of a hair.

So I'd say this job just isn't possible sorry.

It's not possible to solder a broken board. More than 10 layers of ultra thin PCB traces, there is no hope to even begin with.

Just transfer all chips to a replacement board.

I was going to supply a sort of fix but I'm only an 'expert' on the 5.. ;d

I'm not entirely sure, however, I assume the 6 and above use multi-layer circuitry in their mothererboards which.. well, is less than a 4th of the width of your hair. ;p

Looking at that part though, that shouldn't affect the camera or the things you've mentioned, though judging from your event, I'd say there's more underlying breaks and afflictions to the device than you've found.

If it was old school tech then you could fix it. But as the rest above state there are layers in the new circuit cards and the traces running through the layers in your broken boards have extensive damage. The first image has small IC chips to the right of the break and the leads to that chip were probably running through where your crack is. Just looking at that one alone I would have to say that that board is non-repairable.

The second one shows damage to the plastic connector which might still function but it has a lot of damage.

I hope you paid for the Apple Care or Can Get Apple Care and then get a Replacement.

The only chance to save the Board is to literaly transfer Every chip and Capaciter onto a new, empty board. You can get these from iFixit at ~$10

Hi! By saying“transfer every chip on to a new board”, what do you mean? Does this mean I can get my photos back??? Logic board of the phone is broken and I lost my data
