A new video has surfaced that gives us an extremely rare look at the iPhone assembly line within a Foxconn factory. Seeing one of these lines in action is a very rare occurrence as Apple is well known for keeping its production processes and products secret. The video is shot in Foxconn’s Zhengzhou plant where over seventy percent of Apple’s iPhones are now made.

The video which is provided by iFeng, shows a Chinese reporter with Foxconn CEO Terry Gou taking a tour around the extensive factory. The tour starts in a helicopter to give an idea on the sheer size of this huge factory. It covers 5.6 square kilometers (2.2 Square miles) with more expansion planned and employs around 115,000 workers.

The factory part of the tour starts off in the iPhone 4S production line where you can see the iPhone 4S frame and motherboard. The motherboard line is 148 meters long and rolls out 10,000 units a day. The tour continues into the camera assembly area which is all done in a clean room environment.

You can watch the video below, the dialogue is all in Chinese and we don't have a translation yet.
