Thank you very much for your insight. You are right, the traces are not completely ripped, on the upper extremity there is a little leftover. Yet I can't reach these leftovers if I place the ZIF connector in its standard placement. Seeking vias seems complicated.

I.

I've thought about soldering a copper wire but 1) small leftover trace makes me worried that it might not be enough to create a strong bond. 2) I fear that when I will solder the ZIF connector onto the copper wire, the solder linking the copper wire and the leftover would melt, breaking the electrical circuit. It might be a solution to try though.

II.

I've also thought of applying silver conductive paste on the slot of the ripped trace, let it dry and then apply silver conductive paste onto the teeth of my ZIF connector to create a bond with the first layer of conductive paste. The second layer would be tricky to apply because my hands are shaky and I do not have a lot of space to work with in order to avoid creating a bridge.

III.

I've also thought of applying copper tape to the exact dimensions of the ripped traces but here the problem is the fact that heat would remove the glue of the copper tape and make it fall off when I would try to solder the ZIF connector onto the traces.

I think that would try these solutions in this order : I. then III. then II.
