Is the 6 Pin Socket of the NFC-PCB solderable

Toniebox Hardware Repair
1

Hello everyone,

I got a broken Tonibox from my brother which only gave a sound when I pressed down hard on the maintenance slot at the bottom. After taking it apart I quickly found that one pin of the 6-pin socket of the NFC-PCB is broken off (and only connects if pushed into it).

Now, I thought of soldering it back onto the PCB, but the connection does not look like it’s solder at all. Its more of a gray powderish paste. So my questions are:

  • Can I solder it, or is there a better alternative (e.g. because the area is heat sensitive and thats why the gray paste was used?)
  • Would you recommend removing the socket completely, cleaning the connections, and soldering every pin?

Thank you in advance,
Best wishes.

This is solderpaste. It could be enough to heat the pads to reflow it.

I could not get the paste to reflow. However, with a bit of flux and solder, I got a strong connection.

Thanks for the help.
