1. integrated circuits (integrated circuit, abbreviated: IC)
2.
3. Special electronic components.
Broadly speaking, it also involves all electronic components, such as resistors, capacitors, circuit boards/PCB boards, and many other related products.
IC according to the function can be divided into: digital IC, analog IC, microwave IC and other ICs, of which, digital IC is the most widely used in recent years, the fastest growing IC varieties. Digital IC is the transmission, processing, processing of digital signals IC, can be divided into general-purpose digital IC and special digital IC.
