I have a computer from the late 80's, the keyboard flex circuit is the culprit. I was hoping someone could advise the best way to try to repair it. It has broken traces visibly obvious from inspection. Some traces are "dim" and look worn away inside of the laminate. there is 1 trace that had a drop of something spilled on it and it ate through the laminate. I attempted to use a silver based circuit writer by CAIG. It did not repair the tiny hole through the single trace. (that is 2 times I attempted to fix broken traces with it to find out it failed)
I was informed by someone years ago that they successfully peeled the bottom and top layer apart. Anybody have any idea how that could be done neatly?
The top layer where the buttons make contact has a green clear color, with bridges of some sort? the bottom layer is clear like a license. The traces are silver, Im guessing aluminum?
I contacted many companies in China to get some reproduced, but they all wanted gerber files, and I have no idea how to make 1 of those files. The quotes without gerber files were ridiculous.
I would buy another computer, but it would not be cheap, and it would be difficult finding the same model. & the keyboard could be problematic with the duplicate computer.
Any help or advice is greatly appreciated. Thank you all!
EDIT: here are pictures of the circuit in question, I tried my best, but my camera is garbage.
