that flex ribbon looks completely modular. you may want to look into the more simple answer of replacing the ribbon. since no large components seem to be mounted to it, you can likely get the part for between 2$-15$ from a source if you have access to suppliers for camera parts. you would likely be putting more value of labor into repairing it at that point.
i appologize, but i do not have a meathod to do this repair for you, but i hope you take my suggestion under consideration
