Inside Chinese smartphone maker Oppo’s Shenzhen factory, the company is twisting, dropping, and tapping its devices to make sure they’re ready for primetime.
Shenzhen, a modern metropolis that has become a hub for China’s technology sector, is home to one of smartphone giant Oppo’s nine factories in the region, and we got a look inside.
It’s where Oppo builds its latest devices, including the Reno 2, the upcoming Reno 3 5G, and the Find X2, which have proved popular in Europe and India but have yet to hit the United States.
Inside the building, reels of resistors, transistors, and capacitors fed through expensive machinery that automates the manufacture of motherboards. Robotic arms, like those you’d find on any assembly line, put newly minted phones through dual-camera, antenna, and GPS tests.
At the end of the manufacturing process, the phones are put into two rooms: one made out of metal, which reflects radio waves and tests the average power of the device; and another, completely dark, which mimics the phone being used in an infinite space without any invisible interference.
That’s not the end of the story, though; before the phones are ready to be sent into the world they go through rigorous testing. Read on to see what Oppo devices endure before they’re shipped to consumers.
