What are the Foxconn Assembly Lines?

I'm doing a school project on the iPhone being Made in China, and I really need to know what the "Assembly Lines at the Foxconn Factory" are in order; do they start with the motherboard, or the housing, etc, etc?

Actually the entire design and some parts of it are made in the US, its mostly the assembly and some parts that are done in china.

  • Where can I buy an Iphone 5C LCD assembly?( not online)? I need one in the next few days and shipping isn't fast enough anywhere due to weekend and holiday, so I'm looking for advice.
  • What would happen if assembly line wasn't made? If Henry ford didn't invent the assembly line what would be happening today? Like how much would famous products cost be? Like iPhone, how much more would the price for iPhone be, or any other famous products? What would be cars prices? Would there be less cars? What would be the situations for employment would there be less people or more? How does assembly line help the daily life for all of us?
  • Rainbow lines across iphone screen? I got my iphone 4s about a month ago and i've had the lifeproof case on it since day 1. I have never dropped it, or gotten water on it etc. Today i was in the midst of typing a text message, when i noticed some multicoloured lines going horizontally across my screen. When i went to my home screen i noticed that half of my screen is completely like that. Everything is still fully functioning for the time being, but its really annoying! How do i get rid of this?
  • My iphone screen cracked and now has black lines going through it I dropped my phone and the screen now has this fuzzy look with all different color lines on the screen. The touch censors still work. So will i only need to get the screen replaced or is the phone destroyed?
