I'm a junior student, and now my teacher give us students a task to write a report about the printed circuit board(PCB). I choose the FPCB, and I want to write "The Classifications of the FPCB". I have looked for a lot of related information, and I found a relatively detailed article, which mentioned that it has two kinds of classification methods: "Classification according to the Combination of Substrate and Copper foil, Classification according to the Structure of FPCB ", from http://www.kynixsemiconductor.com/News/71.html. I don't know whether the two methods are correct or not. Hope you guys can help me to judge it.

Thanks firstly.:):):)
I got to know that there are various classification methods of FPCB, the article I referred just is relatively comprehensive. I want to adopt these methods but I'm not sure that it's right. Or can you suggest what the correct classifications of the FPCB are?
