How to reattach LCD flex cable to LCD
I am operating a phone repair and lcd refurbishing center. I currently replace backlights, polarizers, and top glass on the displays but sometimes i am dealing with a fully functioning lcd that has the flex cables removed. How do I reattach the flex cables to the lcd and what kind of equipment is used? It would be a shame to get rid of a good lcd just because of the flex cable. Right now this question is centered around the iPhone 6 but any answers will be helpful.
