help: ribbon cable repair

[Ching Kong]

hi.
Does anyone know hot to repair broken copper ribbon cable? You know, the
flexible flat cable that consist of copper ribbons sandwiched between two
layers of orange plastic.

I was thinking either use solvent to dissolve the top plastic layer, or to
abrasive to sand it off, to expose the copper so that I can solder the
thin conductor together. However, I don't know what solvent to use, or
what is the best method... Please help me. TIA.

The best and most reliable method is to replace the cable with a new one.

I prefer to carefully shave off very thin layers with the edge of a razor
blade.
Careful not to cut foil.
Some flux, and a soldering iron at low heat, and a quick hand, you should be
able to resolder them without melting the plastic cable...

yeah, i know. But the ribbon costs almost as much as a new device (BJ
printer).

Download document 00-25-234 entitled "General Shop Practice Requirements for
the Repair, Maintenance, and Test of Electrical Equipment." Pages 9-1 through
9-9 address repair of kapton-insulated ribbon cables like the one you're
describing. There's a lot of other useful stuff in there too, by the way.

Good luck!
