Xiaomi company a few days ago invited the media to visit the industrial technology

Foxconn complex in Langfang. It is here that most of the Xiaomi Mi 9 smartphones are produced. The media managed not only to learn in words how exactly the flagship assembly process takes place, but also to look at the production lines.

Production Xiaomi Mi 9

In the process of assembling Xiaomi Mi 9 passes a fewproduction lines. At the first stage, we work with the components of the main PCB, which are placed on the production line. Almost all of them use automated robots, but also living workers control and are responsible for checking and adding components.

Telephone chip, resistors and capacitorsare placed by the robot in accordance with the given coordinates on the main board, and then the entire motherboard is processed through a specialized reflow oven. The robot can very accurately and quickly complete the installation and soldering of the chip. Interestingly, one production line can produce about 8,000 motherboards for smartphones per day.

The next step is to add Xiaomi Mi 9motherboard, screen, camera, speaker, battery, wireless charging coil and other components. At the same time you need to check whether the components are working correctly.

The final step is to install the rearparts of the glass on the fuselage. Thanks to the exact location, the back cover fits snugly to the case. When the build is complete, the smartphone passes a stress test. If everything is good, then after that Xiaomi Mi 9 is treated with p2i, as a result, the phone body is covered with a nanoscale coating to make it hydrophobic. This will prevent the ingress of liquid, thereby achieving a level of protection against splashes. The whole process of p2i lasts 3 hours.

The last production line isdirectly packaging the smartphone. When Xiaomi Mi 9 gets here, the final tests take place with it, including the screen and the camera being checked. Further the license, a bar code and a screen film is put.

After production is complete, smartphonessome time stored in the warehouse of the factory, and then sent for sale. Since Xiaomi Mi 9 is very popular, it does not stay long in stock.

For reference, by the end of March more1.5 million Xiaomi Mi 9 series smartphones, including more than 1 million original Mi 9 phones. The factory is currently working overtime to produce more smartphones.

Also, Xiaomi explained that there aretwo main problems affecting the volume of production. First, the supply of camera modules was relatively small. Secondly, during the last month the level of skill of the employee has been constantly improved. By mid-March, the problem of limited production capacity was gradually resolved.

By the way, in the process of assembling Xiaomi Mi 9 participatethree manufacturers of smartphones, including Langfang Foxconn, Nanjing Yinghuada and Xi’an BYD. Among them, Langfang Foxconn is responsible for most of the production.
