Hardware Mulitple USB-C pads destroyed any rescue?

[w0nk1]

Hi guys,

I've currently a Nintendo Switch where multiple USB-C pads are destroyed, do you think there is any way to fix that? Even if HDMI-Out or smth. wouldn't work? I am kinda desperate actually :-/

You need microsoldering tools, a microscope or magnifying glass and patience to repair missing pads. Below you will find some videos on youtube where you can see how they are rebuilt....

Thank you very much FXDX, I will have a look!

It'll be an experience. A microscope may be recommended but if you can see the traces coming from the pads, you can sand/scrape off the coating on the PCB (don't breathe it in either, it can be made out of nasty stuff) to expose the trace, and then replace the pad with some very thin copper clad or circuit track.

All of the pads you ripped off but one are luckily going straight to vias. Solder them from the underside of the board if you are having problems.

Thanks for your help guys, I ordered a stereoscopic microscope and try to establish the connections again! Should be a nice lesson!

Which one did you order?

Damn that's a big investment for such a small job. Hope it's not just for this repair.

 

[w0nk1]

Yes, it is a big investment. No, I just want to push me to microsoldering, where such microscopes shall be mandatory.

Just for information: I wasn't able to repair the ripped of pads as a consequence of to less contact points from the vias (unfortunately the vias does not exit underneath the board). In result of that it was to flimsy with a tiny copper strain.

Nevertheless I was able to get the charging working again. So at least a partial success!

Did you scrape back the trace a bit for more to hold onto? I usually scrape 4mm and solder a wire down with flux and then cover all but the end with clear nail polish (alternative protective coating).

 

[w0nk1]

I tried that, but in fact there isn't much to scrape in this area. :-/ But I have to admit it is tough work for my 101 lesson. ^^ I guess someone else could had handle it.

The advice with clear nail polish is a good point! I will try that in the future. Thanks!
