What is the meaning of a circuit board?

1. PCB (Printed Circuit Board), also known as Printed Circuit Board in Chinese, is an important electronic component, the support body of electronic components, and the carrier of electrical connection of electronic components. Because it is made by electronic printing, it is called a "printed" circuit board.


2, meaning: electronic equipment after the use of printed boards, due to the consistency of the same type of printed boards, so as to avoid the error of manual wiring, and can realize automatic insertion or placement of electronic components, automatic soldering, automatic detection, to ensure the quality of electronic equipment, improve labor productivity, reduce costs, and easy to maintain.

Extended Information:

Circuit board according to the number of layers to be divided into single panel, double panel, and multilayer circuit board three major categories.The meaning of the circuit board is also obvious.


1. The first is the single panel. In the most basic PCB, the parts are concentrated on one side and the wires are concentrated on the other side. Because the wires appear on only one side, the PCB is called a single-sided circuit board. Single panels are usually simple and inexpensive to make, but have the disadvantage that they cannot be applied to too complex products.


2, the double panel is an extension of the single panel, when the single layer wiring can not meet the needs of electronic products, it is necessary to use the double panel. Both sides are covered with copper wires, and the wires between the two layers can be guided through holes to form the required network connection.


3, multilayer board refers to a printed board with more than three layers of conductive graphic layer and insulating material between the layer is separated by lamination, and the conductive graphic between the interconnect according to the requirements. Multilayer circuit board is the electronic information technology to high speed, multi-function, large capacity, small volume, thin, lightweight direction of the development of the product.

According to the characteristics of the circuit board is divided into soft board (FPC), hard board (PCB), soft and hard board (FPCB).


The name of the circuit board is: ceramic circuit board, alumina ceramic circuit board, aluminum nitride ceramic circuit board, circuit board, PCB board, aluminum substrate, high-frequency board, thick copper plate, impedance board, PCB, ultra-thin circuit board, ultra-thin circuit board, printing (copper etching technology) circuit board and so on. The circuit board makes the circuit miniaturized and intuitive, and plays an important role in the mass production of fixed circuits and the optimization of the layout of electrical appliances.Meaning is everywhere.


Printed circuit board (PCB circuit board) is an indispensable part of modern electronic equipment, usually electronic equipment, whether large machinery or personal computers, communication base stations or mobile phones, household appliances or electronic toys will be used printed circuit board.


The composition of printed circuit board is mainly insulation substrate and conductor two kinds of materials, in the electronic equipment to support, interconnect and part of the role of circuit components. Integrated circuit and resistance, capacitance and other electronic components as a single individual is unable to play a role, only in the printed circuit board has a foothold and a lead junction to connect it, in this whole can play its function. The printed circuit board is the skeleton of the supporting components and the pipeline connecting electrical signals. In addition, some printed circuit boards with resistance, capacitance, inductance and other components, become a functional circuit, play a role in the tube.


The role of printed circuit board in the electronic machine equipment is: for the transistor, integrated circuit, resistance, capacitance, inductance and other components to provide a fixed and assembly of mechanical support; To achieve the wiring and electrical connection between transistors, integrated circuits, resistors, capacitors, inductors and other components, electrical insulation to meet its electrical characteristics; It provides identification characters and graphics for the inspection and maintenance of components in electronic assembly process, and provides welding resistance graphics for wave crest welding.


The printed circuit board is used in the electronic machine, which avoids the error of manual wiring, and realizes automatic fitting, welding and inspection. So as to ensure the quality and reliability of electronic machine products, but also improve labor productivity, reduce production costs, convenient maintenance.


The meaning of circuit board includes the above knowledge points. In this era of rapid development of science and technology, circuit boards, computers, mobile phones, refrigerators, headphones and other electronic products everywhere around us are all used circuit boards. In the future, we will always be with circuit boards.
