Nintendo Switch, repairing damaged or lifted pads on USB-C port !

hey!

the measurements were made without battery and not mounted, but I did some measures on a different board without battery etc.. and it has got the correct values.. so I guess it's really the cpu.

okay.. I removed a CPU in the past and I got off more or less smooth, but today I tried it on a differend board, I heated at the CPU with 400°C and some air flow and it didn't got off after 15 minutes! completely crazy, was a water damaged board. I'll try some reflow with flux. can you recommend for how long I should heat up the cpu?

thanks!

 

thanks a lot for the detailed description, I'll try it tomorrow :-)

In the meantime I continued with the other (water damaged) mainboard, just for practicing. I wasn't able to get the CPU off the board again. I already got the CPU off of another board, just that you don't think I'm crazy, but I was able to get CPU off the board only by sheer force. I had to use tweezers unterneath it.. I guess there was some kind of glue, or the chip itself melted onto the board because of the water damage. Were you ever facing this such an issue?

As already mentioned I'll continue with the other mainboard tomorrow.

 

@FXDX

I did a reballing today (took me the whole afternoon :-D) but still the same issue on these pads. I also checked the pins on the CPU itself, but there was no short. So can this issue be caused by something else?

thanks!

 

thanks :-) the switch won't turn on. I reballed the CPU because of these problems:

or please check out my post from Apr 26, 2020

 

hey!

I replaced both, but it won't boot or show anything on the screen even with a charged battery...

cheers

 

thank you this is really helpful .... i fixed one yesterday by this method

 

i HAVE the same.... maybe is the MAX17050 chip?

whats a good battery voltage to boot the nintendo switch please? @seidolino

 

hello, I am curious as to why you left out SBU2, RX1, and TX2 from the pinouts. I found where they go, but are they not necessary for anything (docking, usb bluetooth dongle, etc)?

 

Hi ,
dreds here
Just joined and am interested in this sort of thing ,
Done a few repairs a while ago on 360 s and a few PS4’s but I like the intricate work done on Nintendo switches ..
have a question for @FXDX
I have a switch with 3 pads left lol !! I tried to run wire to pads but not successful, I get 0.17- 0.20 where as before I got 0 ..
I have a feeling I’m going to have to run jumper wires from front pins and back ones also .. I have 0 pads left on the hidden pins ..
I see you put a bit of connector cable and soldered to that , could I solder directly to the pins , I know this is not going to be an easy task but I like a challenge
You did an amazing job on this port , !!!! Really amazing work !!
I’ll upload some pics

thank you
Dreds
