We looked on Amazon but looks like the adhesive side is not conductive.
Can you suggest us the model of copper tape you have used ?
Take care anche thanks again Alberto

I used this tape from Adafruit. The adhesive is claimed to be conductive, but it wasn't conductive enough to satisfy my continuity tester, so what I ended up doing was to cut the tape into squares with a tab (see crude diagram below), then remove the backing to expose the adhesive, fold the tab under the square, then press the square onto the PCB, so the copper surface of the tab makes direct contact with the pad on the board.

Hope that made sense. Good luck!
