This is "not unlike" fixing a PCB trace. How would you do that?

What about globbing some eutectic solder over the traces (even though

it
shorts them), then using "something" to break the solder into

individual
"strands" while it's still liquid?

I'm wondering whether zebra strip would be conductive enough? It might
not matter over such a short (ar, ar) distance.

I wish you success. And if this happened this morning, please put it
aside and relax. Work on something else, something easy, and try to
forget about this problem for the time being.


Flexible pcb connector as in a ribbon connector? I've had some limited
success repairing these with conductive paint designed to repair
automotive window heaters.


Its a paper thin flexible pcb, golden brown in colour which I think is

made
from Mylar. Because of the narrowness of the tracks and their spacing I
doubt it could be done with paint.

If heat resistant then probably kapton tape. If signal levels and you have a
fairy godmother then anisotropic tape is another possibility , if you can
bare back to the underlying condusctors .
