A factory where nokia phones are made. Currently there are 9 such factories around the world.
Well...Find out how your NOKIA phone is developed
Step 1 - All the electronic components in a phone, like memory chips, microprocessors, resistors, capacitors etc.. are produced by outside suppliers in mass scale. Then those are delivered to the factory, attached on reels of tape protected in circular plastic cases.
.
Step 2 - A circuit board which has a latticework of basic circuits, is inserted into a “paste printing machine”, which applies a patterned layer of solder paste on the surface—printing of circuit board.
.
Step 3 - The reels of tape containing electronic components are fed in to automated "pick-and-place machines” where those components are removed from the reel and pasted on correct places in the printed circuit board.
.
Step 4 - Printed circuit boards travel through a series of pick-and-place machines and after reaching the end, printed boards are inserted into an oven where they are melted causing the added components to attach firmly to the circuit board.
.
.
Step 5 - Circuit boards are loaded onto ‘tracks’ automatically. There, first quality test takes place and then basic software is installed into programmable components.
.
.
Step 6 - Circuit board are taken off from the tracks, by a specially designed robotic arm and are placed in a bay where low-level settings such as power settings are configured in electronic components. After this, a series of electronic tests are carried out in order to ensure, whether the circuit board is perfect, all the parts work, and that they have been correctly installed.
.
.
Step 7 - From this point forward, development is mainly performed using human hands/manually. Mainly, removal of some components, like expensive and fragile liquid-crystal display screens, from the reel and pasting them on a circuit board is done manually.
This picture shows a worker adding a digital camera module/component, which has been removed from a reel using tweezers, onto an assembled, tested, printed circuit board.
.
.
Step 8 - Completed circuit boards are sandwiched between front and back structural frames and then phone’s outer cover is applied.
.
.
Step 9 - Here, turning the phone into a usable model is done. This includes installation of set of menus, features and setting up of the start-up screen for each different phone type.
In addition, a serial number called ‘IMEI code’ which uniquely identifies the phone given.
At the end of this stage, the phone and installed software undergo a battery of diagnostic tests.
.
.
Step 10 - All the phones undergo a final inspection by human eye. Phones that pass the inspection/test are de-ionized to remove any electrical charge and dust from the surface.
.
.
Step 11 - Phones are packed into retail boxes by hand, with appropriate documentation and accessories. Then these are logged into a tracking system using a bar-code reader.
.
.
Step 12 - Finally brand-new phones are packed into boxes.
.
.
Step 13 - Containers carrying boxes of phones are transported and distributed throughout the world.
