  • Today we are at the GIGABYTE Factory in Nan-Ping, Taiwan

  • to show from beginning to end, exactly how a GIGABYTE motherboard is made.

  • A motherboard uses a lot of components, all of them are assembled on a PCB

  • PCB means Printed Circuit Board

  • creating the motherboard you will recognise from inside your PC.

  • The PCB arrives from another factory and the first process is to solder on the board all the SMDs

  • SMD means Surface mounted devices.

  • SMD is a term use for all the components that don't have pins going to the other side of the PCB

  • but have their electrical connections on the edges.

  • like the resistors, bios, audio and sata chips, as well as the chipset itself.

  • Every part of the PCB that will be in electrical contact with a component gets coated with a special soldering paste

  • The solder paste acts like glue for all these chips before going into the reflow oven for definitive soldering.

  • In that way every small component is in the right position before soldering.

  • As you can see, the solder paste is applied on the PCB space only in places where you will have components.

  • All motherboards today have dozens of very small and thin SMD components that are directly placed on the board.

  • The high speed Chip Placer can place from 5 to 10 components per second. It's incredibly fast.

  • Most of the components mounted by these machines are around a millimeter wide

  • and must be very precisely placed on the PCB.

  • Today's motherboards have components on both sides,

  • the first side that goes into the factory process is the reverse side.

  • Once the reverse is done,

  • a machine switches the motherboard to the front side

  • and the process starts again on the SMT Line.

  • After the small components, it's time to mount the chipset

  • CPU socket and all the other chips that will made your motherboard work.

  • Before being placed on the motherboard,

  • each chip is first verified by different sets of lights to check if there is any problem

  • with the soldering points or alignment of the chip.

  • You can see that chips like the chipset, audio, SATA and USB ICs

  • are placed on the board by this machine The same goes for the CPU Socket.

  • For example, all chips that are bigger than your finger are placed by this machine.

  • Now that your motherboard has SMDs on the board, it is ready to go to the Reflow Oven for the soldering process.

  • The soldering paste is melted at very high temperatures, sticking the components to the PCB.

  • Temperatures reach as high as 245°C as the motherboard moves through the different levels.

  • At this point electrical and mechanical connections are made.

  • Now that your motherboard has all the small resistors as well as the major chips and the CPU socket

  • it's time for the visual inspection.

  • This inspection ensures there are no misplacements or missing parts.

  • Components smaller than 2 millimeters cannot be checked by visual inspection, but this is why we have the AOI machine.

  • The Automated Optical Inspection machine checks if there are any missing or misplaced components.

  • It also checks all the components that have visible soldering point, like the audio chip.

  • And finally the ICT, or Integrated Chip Tester stage, can verify that every chip that has soldering point below,

  • like the chipset, is well connected.

  • It tests if the chip is well-soldered electrically to the board,

  • but does not test if the chipset itself is working.

  • This factory floor is dedicated to additional verification, especially for server components.

  • Some boards are tested by X-Ray to verify the quality of soldering.

  • This inspection is a high quality service that allows very high-end and server board to be checked in more depth.

  • And server board to be checked in more depth.

  • Once these last tests are made after the SMT stage, it's time to go to the DIP or Dual Inline Package stage.

  • The DIP stage is the second major process when making a motherboard.

  • First you have manual insertion;

  • with all the small components and ICs has been already added

  • it's time to place all the other components that have pins going through the PCB.

  • During this stage all the components are manually inserted.

  • You can see a long chain of employees inserting the I/O connectors

  • power sockets, PCI-Express and ram slots

  • also the chokes and solid capacitors around the CPU Socket.

  • Before being finally soldered on to the PCB

  • each inserted part needs to be in the right place and well positioned

  • this is the goal of the inspection before the wave soldering.

  • The principle of the wave soldering is easy

  • the motherboard has components on one side, with pins going through the PCB

  • The Wave Solder touches the back of the PCB

  • and these pins are soldered to attach the components to the board.

  • After the Wave Soldering process

  • you usually have residues that are cleaned with a large brush

  • making the back of your motherboard shiny.

  • Another inspection is made, with manual touching-up with a soldering iron if needed.

  • Then heat-sinks are mounted on the board before another inspection

  • and check-up by the ICT or Integrated Chip Tester.

  • Your board is now fully functional,

  • but the biggest quality control still needs to be done.

  • Employees are testing everything. From component connectivity, to the all important burn-in test.

  • The Function Box allows easy "Switch ON / Switch Off" of the components

  • as well as peripherals for testing purposes.

  • As a part of GIGABYTE's rigorous quality testing procedure, 100% of the boards' components are tested

  • with basic to advanced functionality fully verified.

  • Once the board has passed all the testing and quality Analysis,

  • the boards are sent to the next process: The packing.

  • This is the final step for your motherboard

  • where it makes its way into the box you'll see in the shop.

  • At the factory the boxes are just flat cardboard

  • The packaging starts off as flat packed cardboard boxes that are quickly fashioned into retail boxes by an automatic machine.

  • Employees apply barcodes and references numbers on the boxes,

  • as well as on the board, then scan the different serial numbers.

  • Your board is almost ready.

  • The bundled accessories that include the manual and drivers DVDs are added,

  • Each motherboard box goes into larger boxes ready for shipping (These are then weighed and strapped up before being send to distributers and retailers).

  • This ends our video detailing how GIGABYTE Motherboards are made.

  • We hope you enjoyed this OverClocking-TV video and look forward seeing you again soon. �
