Although the Bank of China version of Mate 9 has not yet been officially released, some netizens have released the disassembly drawing of its real machine. Overall, the internal structure design maintains Huawei's consistent style, which still uses the main board+battery+secondary board, and uses a large area of flat cables to connect the main and secondary boards.

According to the netizen, the back cover of the real machine adopts the design of large-area nano injection+outer layer sticking plastic shell, and the specific process is not clear. From this figure, we can clearly see the large area of cabling between the main board and the auxiliary board.

The most significant change is obviously that the machine uses Leica tuned dual cameras, and Mate 9 adds laser focusing, so the flat cable between the back cover and the motherboard has been increased from one to two. The following is the disassembly drawing of Mate 7 and Mate 8, which can be used for reference by interested users.

The disassembly drawing of Huawei Mate 7 is as follows:

The disassembly drawing of Huawei Mate 8 is as follows:
