I have a set of accutech strain gauge electronic bathroom scales. The lcd
started behaving erratically recently (scales are a several years old). As
a matter of interest I pulled them apart to have a look. The lcd is
connected to the pcb by a clear plastic? film with fourteen carbon? tracks
about 2mm wide. It seems to have been glued to the pcb which has
corresponding copper pads. When I went to replace the pcb in the case I
noticed that the film had completely come away from the pcb.
There seems to be no way to reattach it other than regluing it.
I was thinking super glue but is there a specialised conductive adhesive
which could do the job?
Or some sort of edge connector which could clamp onto the film?

Is scart now defunct? Does new equipment still use it?
