Hello guys, I have an Iphone 6s that was dropped on the sea, and has EXTENSIVE water damage, the board itself is a mess beyond repair. I want to know if its possible to move the key components to another board ( maybe those that you can get on ebay with bad EMEIs or ICloud locks) and maybe get the phone to work again ( using my original chips in it). I have experience on soldering and have done some research on how to proceed ( using hot air to get the chips out, etc etc), and I think that with some trial an error I should be able to do it. Thoughts?
Technically speaking, this is possible. You would have to move all of the paired components over to an otherwise functional board. That would be the CPU, NAND, Baseband, EEPROM and maybe some other bits. I don’t know exactly because this is not a repair I typically offer so I have not researched it fully. Realistically speaking, this is essentially an impossible repair unless you are a very advanced micro-solderer. The CPU is a dual-layer IC (CPU/SDRAM) that has ~35x35 grid of tiny solder balls underneath a 1/2 inch x 1/2 inch die. Considering the amount of heat you will have to blow across the logic board, this is not really a trial and error repair. You will have to try this multiple times on dead boards and then eventually on a good board to see if the process actually works electrically and digitally without blowing out solder balls all over the board. Only then do you attempt the repair. Now, educationally speaking, this is a fantastic project and I encourage you to do it but start with smaller IC’s first to get a feel for your gear and skills and move your way up. Report back too so we can all learn from it as well.
