There are many forms of matter, such as solid, liquid, gas, plasma and so on. We usually call materials with poor conductivity, such as coal, artificial crystal, amber, ceramics and so on, insulators. Metals with good conductivity, such as gold, silver, copper, iron, tin and aluminum, are called conductors. The material between conductor and insulator can be simply called semiconductor. Compared with conductors and insulators, the discovery of semiconductor materials is the latest. Until the 1930s, when the purification technology of materials was improved, the existence of semiconductors was really recognized by the academic community.

Nowadays, the automobile industry is developing towards intelligence, networking and sharing. ADAS and automatic driving technology are also advancing rapidly

PCB (printed circuit board) is a printed circuit board, which is one of the important components of the electronics industry.
