Sd card reader plug thicker

Hi everyone,

I'm looking for some advice or assistance with a Nintendo Switch SD card reader repair.

I originally had to replace the SD card reader, so I purchased a new replacement unit. Before installation, I compared the original reader with the replacement and noticed that the solder on the pins of the new reader appeared noticeably thicker than the original.

I've taken photos of:

• The original SD card reader pins.
• The replacement SD card reader pins, showing the difference in solder thickness.
• The motherboard connector where the SD card reader plugs in.
• The damage that occurred during the replacement attempt.

Unfortunately, while attempting to install the new reader, one of the pins on the motherboard broke.

I'm trying to establish what may have caused this.

Could the thicker solder on the replacement reader have prevented the pins from seating correctly or caused excessive pressure during installation?

Alternatively, could this be a manufacturing defect with the replacement SD card reader, particularly given that its pins appear different from the original?

I'm also open to the possibility that the damage was caused by my installation technique.
