Question Alternative soldering points for the mx chip relocation

[Jason59430]

Hello, I’m a little annoyed. I wanted to move my MX chip, but the connection corresponding to data line 14 is torn from my Wii. Is there another connection point?
You will find the line that is torn off on the attachment, thank you for any information
(The Wii works, I’m playing it right now.)

You can just scrape the trace of data line 14 with an xacto knife or something similar, being careful not to scrape any ground or other traces, then just tin that and solder to it. You want to scrape it further down so you have room to try again if you mess up.

Thank you for your response!

Just to make sure I understand before we proceed: is the remaining exposed part of data line 14 still connecting somewhere internally, even if visually it looks like an open circuit?

From what I can see, the trace seems to stop after the damaged area, so I want to make sure that scraping and welding of the remaining trace will always restore the connection.

Well if you're going to get it working at all, this is your best bet. I'm hoping that the damaged area is just on top, because otherwise the connection is completely severed. If the trace still has some small connection to that via, you should be good. But other than that, you'd have to dig down into the via or something similar.

I will try and come back to say if it works, thank you for your help in any case

I'm afraid if you ripped up the entire accessible part of the via, then there isn't anything you can do. The other side of that via is under the CPU/GPU dies, which is not accessible.

Maybe if you used very thin wire like 38AWG magnet wire, it might be possible to salvage, but it's likely that you will need a new Wii.

I still have a pewter ball soldered inside the via, it stays well in place and I believe that a small part of the Via’s ring has survived, with caution I think it can catch up and if I don’t succeed, never mind at least my ashida is still functional

Better than 1 of the wifi vias.

It’s good, I managed to solder the MX chip and my RTC battery the first time , the internal walls of the Via were well intact, I consolidated everything with resin.

Thank you all for your help
