I have a couple Interphone F3s bluetooth units that I use with pillions, but one of them has packed up.

It turns on fine and connects to other devices, but has no audio or microphone signals when connected to the helmet speakers & microphone.

I've taken it apart and the connector's soldering has come off and doesn't make a connection to the circuit board anymore. It was probably done by a robot that solders a tiny pin sized piece, but this one was defective.

Does anyone know how I can solder this back together? A standard soldering kit will be far too big as the connections are litterally the size of a pin head.

Can upload pics for clarification if needed.
