Is it possible to repair this type of FPC cable? I am a filmmaker and have just basic soldering skills and know this type of repair is beyond me. This is from a LCD Touchscreen. Is this cable repairable?
I've never tried this type of repair, but I have pulled apart plenty of FPC cables for analysis (to make sure they were manufactured properly) .
In the past I have been able to use an exacto knife and carefully scrape off the kapton layer (you'll need a microscope), after the power planes are exposed it may be possible to solder them together with another flat piece of metal such as copper tape.
The problem with this type of repair is it may be too high resistance for the current carried by the cable, or the repair could be too large for the space that the cable was originally in.
In my opinion, its not worth it. It will be a difficult repair. Try and get another cable from the manufacturer or buy a used or broken unit and use that cable.
My opinion only: this cable is most likely repairable IF the person doing the repair has the experience and the skills to do the work.
I would scrape the Kapton layer from the copper, then use either copper foil (thin, flexible) or copper braid (thick, not flexible if saturated with solder).
Be sure to insulate the actual break itself so that you don't short to the conductor on the back side of the flex strip.
Obviously, you will need to repair the conductors on both sides of the flex strip.
See if you can find someone local to you who might be able to do the work for you.
