My understanding of electrical engineering is pretty much non-existent, so please forgive any obvious oversights on my part.
I am currently trying to recover the data from an eMMC chip from a dead phone through soldering direct connections from the chip to a microSD adapter. This example shows in pictures what I am trying to achieve. As I cannot afford an eMMC socket (cannot post more than two links so you can find it on Amazon with product number B01LYUHB33) and the data I'm trying to recover is of sentimental value for my partner's grandmother, I am very keen to try to do it myself.
As it is one of the few times I'm actually soldering my questions are:
- Is this wire that I bought appropriate? If not, do you have any recommendations?
- Do I need to somehow strip the (possibly) very thin coating? Could I use a knife to do this?
- It is my understanding from the example above that the VCC and VCCQ pins should be connected to each other on the chip. Is this necessary? I'd like to avoid as much soldering as possible (lacking both microscope and steady hands), so I'm already skipping connections DAT1-DAT3.
- I'm assuming that I do not need solder balls if the wires are directly connected to the chip (as this is a BGA chip). Is this correct?
If there's any other tips that you can give me, they'd be greatly appreciated. Many thanks in advance.
