Hardware About The MicroSD Card Connector

[DayVeeBoi]

Good idea. But it will take until the sun expands for it to get here.

Also, chances are they send the wrong bit. They don't have many schematics on their listings

I agree, there are many sellers on AliExpress and other than knowing someone or having a particular supplier that you deal with it is likely that it could be a headache.
There is a supplier that I buy console parts from that actually repairs/refurbishes/salvages consoles they are unlikely to send the wrong part if you send a photo and description of what you're looking for.

As far as shipping, I use e-packet for most things, but if I broke my Switch and needed a part asap I wouldn't feel bad about spending $25 on DHL to get it within a day or two. Realistically to get it fixed outside of warranty would be much more painful.

Well, everything is up and running! Thank you very much!!

I never did find the correct part. It isn`t a molex.

The thinnest BTB stacking connector they do is too wide (the central raised nipple bit)

So I chopped the ribbon just in front of the smoothing cap on the SD reader and used some AWG40 to go directly to the testpads, keeping the motherboard side intact. Can post a pinout if it would help...

Hey everybody, sorry for resuming an old thread, but I came across the same problem described and I found your solution which gave me hope.
Now, since I have no competence in soldering, I wanted to take my switch somewhere and explain this solution to someone who could handle it (like a cellphone repair shop), but it isn't clear to me what you meant for "chopping the ribbon in front of the smoothing cap" (no elettronic competence and not being english can harm my understanding skills haha).
Did you mean that you cut off the male connector's wire that is used to connect the SD card reader to the female port on the motherboard?

Also, does the red link mean that the capacitor has to be soldered to that pin?

Thanks in advance

The simplest way of thinking about it, is that the capacitor needs to be between the red and green trace. However you do it.

Connect the green trace, then piggyback the cap on to the green trace somewhere, and the other end is the red trace. Solder to SD reader side of the red trace.

Thanks for answering, I'm really sorry for bothering you
So, from what I'm understanding, this is the wiring I have to do for the capacitor, right?
The green trace just goes from that thing from the motherboard to that pin on SD reader, and the capacitor is connected to that other pin through the red trace, am I right?
I pointed out the capacitor to make sure that's the thing we're talking about.
Thanks again and sorry for being so noobish haha

Well, everything is up and running! Thank you very much!!

hey could you post a picture of your wires need to do this as its a pain trying to add pressure to the male cap every time i wanna restart switch

Updated my earlier post which is HERE <<<<<<<<<<<<<<<<<<

Better graphic. Hopefully.

Happy New Year Peeps!

Oh about that, I met someone who gave me a connector from a donor board he has so I have a proper connector now. Really sorry haha.

@Matius - the damaged points you mentioned go here on the flip side.

Thanks for the reply Matty.

The image I sent via PM, not sure whether it was detailed enough for the actual extensive damage, here's a much better closeup with a Microscope I managed to use.



From bottom to top:

1: Test point seems fine, actual pad for the B2B connector pad appears ripped
2: Test point appears ripped, actual pad for the B2B connector pad appears ripped
3: Test point appears fine, actual pad for the B2B connector pad appears ripped
4: Test point appears ripped, actual pad for the B2B connector pad appears ripped
5: Test point appears ripped, actual pad for the B2B connector pad appears fine
6: Test point appears fine, actual pad for the B2B connector pad appears ripped
7: Test point appears fine, actual pad for the B2B connector pad appears ripped

I really do have a hit and miss with these and it does look some some of the copper trace appears to be damaged from places. I was looking for something exactly as what you mentioned, do you happen to know where the other 5 would go to as I was hoping they would just align with the image you've posted, but it appears not. Thanks for your investigation in the matter.

That's not too bad. I've seen worse boards.

Yeah will put rest of points up tomorrow.

As long as the board is otherwise working, that is straightforward. Only one trace needs a pigtail running round the back. The rest of them, you will get away with

 

[Xyphoseos]

To be sure, the same green wire have to be soldered on the capacitor (with the red one) and on a pin on the motherboard ?

I may have misunderstood, are those two columns ( of test point pairs ) connected to each other. For example, can I use either of the points on the left or right (LIke seen in the image below). The yellow line on your diagram, the pad to the right is completely gone, so am I correct to be able to use the one to left? I wondering if they're both connected. Otherwise, I would then need to run 3 wires from the back them. I posted a diagram if it helps to show which are gone and are there.

Green = Available
Red = Gone



--------------------- MERGED ---------------------------

Connected as in the same trace I should have mentioned

 

[ShadyGame]

So I have these 2 pins missing

Which ones do I have to solder?

 

[tomsek68]

Follow the traces on the board/fpc. I cant make a diagram, as i am posting from my phone.

Also you can use pins from another connector, if you know what you are doing. I found that an iPhone screen female connector's pins will fit nice. I used one from a 5s. Desolder the connector with hot air (or tear it off the ribbon) and break the connector in half. This way two pins should fall off.
Pros:

• No need to replace the whole connector
• No wires to break when you start to fix the other issues on the board
• Eliminates the danger of soldering to the wrong breakout pin

Cons:

• It is hard to put the new pin in place (as it is so tiny)
• You can destroy your connector even further if not careful

I had the same issue with my first switch. but I ended up using it for soldering practice to hard mod my other switches. I have just joined GBA temp but I have kept my eye on this thread for pretty much 3 months sacked it off in the end, because I ripped the pads off, and dont know how to fix it. but I guess I could have a go at soldering to the alt points on the other side of the board. pretty informative post.

Hello mattytrog ,

Can you please help me pinpoint the alternate points at the back to the ones on the front? My nintendo switch has a broken point colored black front your image.

Thank you in advance!

 

[newgen2005]

Can anyone advise me which wires I will need to solder?

I am assuming looking at the images below I will be working with the pink and yellow lines, just 2 wires need to be used to make contact for missing pins?

 

[thebarraster]

I'm missing that pin. From the looks of the pin out it's a ground pin? If so do I just need to connect a wire to the ground on the card reader to a screw on the mobo?
