I have buy a switch with bsod and need help it is bent
what could be broken ?
Looking at the bend the worst looks slap bang in the middle, which probably means the SoC pads are tore and possibly the main PMIC, it’s unlikely you’ll be able to fix this, reserve the board as a donor.
You’d have to move the SoC (and possibly Ram) from the bent board over to a (good, flat) donor board.
Keep the EMMC module together with the SoC (theyr’e paired)
You’ll require, jig, specific SoC stencil and 0.35mm leaded balls.
When removing the SoC, first preheat the opposing underside of the board at about 150C for a few minutes so as not to expose the SoC to unnecessary excess heat. After removal tin the pads with leaded and wick the IC off, the proceed with reballing etc
There is a chance after all that though that the SoC has been damaged and this won’t work
btw if that image above of the board is from the bent switch frame, and if it’s missing the EMMC module, it’s unrepairable, use it as a donor.
So I have 2mainboards and 2emmc in the picture of one mainboard the connection for the Emmc is gone what does that mean when I pack the chips from one to another
and the other thing is I only have the two mainboards available, both of which are partly bent
tbh I think they’re too far gone… i’d just keep these bent boards and use them (and the components on them) as donors.
Keep the EMMC Module that originally came with each board together and matched up, don’t mix them up and don’t mix and match them.
When you eventually get another donor board, you can then transfer the SoC (and paired EMMC module) to it.
what exactly is soc can you tell me ?
Big chip in the middle, aka system on a chip is a Tegra ( ODNX02-A2)
