But circuit boards are used not just in mobile phones, they are used in all the high tech equipment including air-con system, vehicles, alternative power, artificial intelligence system, missiles, weapons, outer space stations, etc etc.
And demand for the 5-7nm chips seems to be dropping (see video), whereas the demand for the larger nm chips is booming.
Eg BYD has a record sale for their NE cars last month and read that each NEV require as high as 2000 chips!
