The integrated circuit board is a carrier for mounting integrated circuits. But it is often said that the integrated circuit board also brings the integrated circuit. The integrated circuit board is mainly composed of silica gel, so it is generally green.
The integrated circuit board uses a semiconductor manufacturing process to manufacture many transistors, resistors, capacitors and other components on a small single-crystal silicon wafer, and combines the components into a complete according to the method of multilayer wiring or tunnel wiring electronic circuit. It is represented by the letter "IC" in the circuit (there is also a text symbol "N", etc.).
According to the functional structure, the integrated circuit board can be divided into two categories: analog integrated circuit board and digital according to its function and structure.
Analog is used to generate, amplify and process various analog signals (referring to signals whose amplitude changes with time. For example, audio signals of semiconductor radios, tape signals of recorders, etc.), and digital is used to generate, amplify and process various digital signals. (Refers to signals that have discrete values ??in time and amplitude. For example, audio and video signals for VCD and DVD playback).
According to the manufacturing process, it can be divided into semiconductor and thin film. Membrane is classified into thick film and thin film. According to the integration level, the integration level can be divided into small scale, medium scale, large scale and super large scale.
