Phone bad book gud

Don’t think I can solder on plastic, plus it would create new thickness and I don’t think that would help some sandwiched membranes, but I’m going for double sided copper tape, that should help I hope.

I was thinking about using thin copper tape, it’s cheap and it should be better that some graphite ink I hope,

Unfortunately the shipping fees would kill me since I’m in Europe, I really wish I could buy a new membrane but it seems like I need to do the repair myself.

Would copper tape suffice as a low resistance trace?
