Huawei's current lack of 5g chips is mainly due to capacity constraints.
Due to the lack of chip foundry, Kirin chips can not achieve mass production. In addition, due to the restrictions of the Wassenaar Treaty led by the United States in 1996, China cannot obtain the latest foreign technology in many fields such as chip design and production. It is also due to this reason, at present, China can not import the lithography machine that can produce high-end process chips, and Kirin chips can not realize the possibility of domestic factories, leading to the interruption of applications.
In addition, although Huawei and Qualcomm reached an agreement to import its latest Snapdragon 888 processor, it is only limited to the 4G version, so we can see that in the latest Huawei p50, the whole system is only 4G version.
This is the general situation of Huawei's lack of 5G.
The current shortage of Huawei's 5G chips is mainly caused by Apple's use of unfair competition and sanctions by the U.S. government.
Another aspect is that because none of our domestic national enterprises can design and produce advanced performance lithography machines, they do not have the ability to produce more advanced 5G chips for the time being, so it has caused a shortage of 5G chips.
