Can You desolder an eMMC chip without soldering it?
ADDITION: Here is your other option without soldering the chip back: You just need to clean your eMMC thoroughly. The big danger, regardless of your method, is getting your chip too hot for too long. You don’t want to pump enough heat through your IC to heat up the PCB beneath it. One good solution is in @AliChen’s answer.
What are the different read / write commands in eMMC?
The JEDEC specification defines different data read/write commands for use with eMMC. The single block read/write – the host reads/writes a single block after issuing a “single block read/write command” Pre-defined multiple block read/write – the host sets the number of blocks to be read/written followed by the multiple block read/write command
What do you need to know about eMMC devices?
It summaries the basic specification that all eMMC devices follow including device architecture, bus protocols, modes, data read/write, and production state awareness. The white paper also lists the criteria decision-makers should consider when evaluating the effectiveness of their Universal Programming equipment.
What is the single data rate of eMMC?
Single Data Rate (SDR) Legacy eMMC devices support a 0-26 MHz clock speed with maximum data transfer of 26 MB/s. They use Single Data Rate (SDR) mode to transfer data. In this mode, a single bit can be transferred on each data line per clock cycle. Later eMMC devices support a clock speed of 0-52 MHz. Dual Data Rate (DDR)
Can a eMMC controller work with a SD card?
The controller can be configured to respond exactly like a standard SD card. The hard part is getting a tiny 153 ball BGA package to fit into an SD card slot. [Trochilidae] accomplished that by cutting open a microSD to SD adapter. He then carefully soldered the balls from the eMMC to the pins of the adapter.
How did Trochilidae hack an eMMC to SD adapter?
[Trochilidae] accomplished that by cutting open a microSD to SD adapter. He then carefully soldered the balls from the eMMC to the pins of the adapter. Thin gauge wire, a fine tip iron, and a microscope are essentials here.
Do you need to desolder a BGA 153 eMMC chip?
For data recovery I need to desolder a BGA 153 eMMC chip from a dead phone. I’d like to maximize my chances of NOT destroying the eMMC chip in the process (the other remains of the phone do not matter since these are dead already). I’ve already watched various instruction videos and I’d say I have an idea of the general process.
