DAT0, CMD, and CLK values to check EMMC breakout PCB adapter install?

[ratgoul]

Hey guys,I have been practicing my BGA work for a while now and I'm ready to tackle the EMMC on my switch OLED to install a PCB re-ball breakout adapter. After I have mounted the PCB and EMMC I was wondering what readings (values and type of test) I should be seeing if all went according to plan? I have the 4 pad breakout adapter with breakouts for DAT0, CMD, CLK, and VDDF which I sourced from abal1000x on github.
Thank you all!

Hello,
I suppose it should be the same values as when doing the normal installation Diode Mode and between 0.6 and 0.9 volts
I would like to know how did you practice, which tools etc. Would like to try this at some point

Thank for the reply, I practiced on a broken switch but I saw a practice set on aliexpress called "bga practice BGA chip BGA153 welding machine practice planting ball and tin practice chip steel mesh board set" might be worth a shot.

these were the readings i referenced in diode mode, pretty sure rst is VDDE. either way it read the same and worked
