Integrated circuit board: refers to the original IC that integrates electronic components such as transistors, resistors, capacitors, and diodes onto a chip. It is usually those electronic products that in order to save space, electronic products that use lighter and more durable printed circuit boards are also a good choice.
BGA, also known as BALL GRID ARRAY, is also a packaging method for organic carrier boards used in integrated circuits. Advantages: small package area, large function, high reliability, good electrical performance and low cost, and can be scaled up.

According to different functions and structures, integrated circuit boards can be divided into two types:circuit boards and digital boards.
Analog is used to generate, amplify and process various signals (referring to signals whose amplitude changes with time. For example, audio signals of semiconductor radios, tape signals of recorders, etc.), while digital is used to generate, amplify and process various digital signals (Refers to the signal with discrete values in time and amplitude. For example, the audio signal and video signal of VCD and DVD playback).
