Tape Repair: Fixing Burned & Damaged Tape Paths - Soldering, Magnifying Glass, IDC Plugs

Question

Hello

I need advice on how to repair damaged tape, such as on a photo.
There was already an attempt to solder but as it turned out one path burned out.
Under the magnifying glass you can see three damaged paths but I do not know what it is made of because tin can not keep these paths.
If anyone has an idea, please help. I have already thought about IDC plugs but they are double-row ....

What's on the other side of this tape? If some piece of print with solder paths then maybe it is not worth playing flex regeneration but soldering directly to the print and plug?
PS It could be glued, but once I tried to regenerate such tapes from the cash register keyboard. It is very difficult to remove the film layer without damaging the path, it seems that the toto is sprayed and very delicate ...

Hello. Could you try with a thin aluminum foil and glue, for example?

It would be possible but the problem is that this tape is made so that between two layers of foil there are these unfortunate paths, that's how it looks

Pedros050 · Answer

And show the plug of this tape does it have one strip or two? And is it covered with foil?

marcin.koz2910 · Answer

More photos. And the tape itself has a layer of foil on both sides to protect the paths against abrasion.

Ok, yen ribbon for 1 pin. So what's the problem that there are still some broken paths on the tape? Are you sure

marcin.koz2910 · Answer

Yes sure. I can't capture it in the picture but one of the pictures shows a mechanical impact that caused damage to the tape.

And this one pin is burned by soldering irons and I do not know how to fix it because you can't solder because foil melts and here the dog is buried.

Those cracks would stick. And if this loss is done as I wrote # 2, fasting can be patience and my idea will pass the exam?

marcin.koz2910 · Answer

As a colleague wrote, the paths are sputtered and very delicate
Each attempt of mechanical interference caused damage to the conductive path.
The infusion for me was that I cut off the damaged fragment and then gently cut the place where the paths run.
Then, in these places, I put on an average 16pin stand for a chipboard
Pins from below were bent, which improved contact.
The keyboard came back to life.
Thank you for the tips and interest in the subject Regards

For posterity I put the keyboard diagram for CEMB C65 which I came across in the network:
