Is it PCB design or PCB production?
No matter which one, it seems to be more promising now, because PCB is still a sunrise industry. Due to the high pollution industry in PCB production, the number of foreign PCB factories has gradually decreased, and mainland China has become the mainstay of PCB production. A big country, but not a powerful one! Judging from the current development of science and technology, whether it is civilian appliances or large equipment, as well as automobiles, military industry, medical treatment, etc., they are inseparable from circuit boards!
