How Motherboards Are Made: A Gigabyte Factory Tour
How Motherboards Are Made: A Gigabyte Factory Tour - PCSTATS
PCSTATS takes you on a guided tour of Gigabyte's Motherboard Factory in Taiwan. There's a lot to producing and testing a single motherboard; a mind-boggling host of automated machines, people and processes. Gigabyte has several other factories in Taiwan and mainland China that each manufacture motherboards, videocards, and other products.

In-Circuit Testing and Visual Inspection

The motherboards now go through an AOI (Automated Optical Inspection) machine which will catch any obvious SMT or soldering defects.

They are then visually inspected by a worker using a plastic mask, so that they can easily spot any missing or misaligned components.

Finally the motherboards undergo an 'in-circuit test' which involves testing each motherboard's circuit paths, electrical characteristics and the chips that have just been added by applying electrical current to certain specific test points on the board. Each motherboard is placed on a special rack and a testing board is lowered onto it, making contact with the motherboard at specific points. Current is applied, and the results are analyzed by the technician running the station. The whole process takes less than a minute.
