The English Printed Circuit Board is printed circuit board, literally translated as “printed circuit board”, and circuit board, PCB board, PCB, etc., is an indispensable part of electronic equipment in today’s science and technology era, the appearance of circuit board for many functions of electronic products and make circuit integration possible. It is mainly composed of welding pad, through hole, installation hole, wire, components, connectors, filling, electrical boundary, etc. The main functions of each component are as follows:

Pad: Metal hole for the pin of a welded component.

Through holes: There are metal through holes and non-metal through holes, wherein metal through holes are used to connect the pins of components between each layer.

Mounting hole: Secure the circuit board.

Wire: The electrical network copper film that connects the pins of a component.

Connector: A component that connects circuit boards.

Filling: The grounding network of copper, can effectively reduce the impedance.

Electrical boundary: Determine the size of the circuit board. All components on the circuit board cannot exceed this boundary.

Circuit board classification:

According to the number of layers, circuit boards are divided into single panel, double panel, and multilayer circuit boards. A single panel, on the most basic PCB, has parts on one side and wires on the other. This type of PCB is called a single-sided circuit board because the wires appear on only one side. Dual panel is an extension of single panel, when single-layer wiring cannot meet the needs of electronic products, dual panel may be needed. Both sides are covered with copper and have a route, and the line between the two layers can be guided through the hole, so that it forms the required network connection. The multilayer board refers to a printed board having more than three layers of conductive graphics layers and insulating materials between them, and the conductive graphics between them are interconnected according to requirements. Multilayer circuit board is electronic information technology to high speed, multi-function, large capacity, small volume, thin, lightweight direction of development products.

The basic design process of the circuit board can be divided into the following steps:

1. Design principle of circuit schematic diagram.

(1) It mainly uses the schematic editor of Protel DXP to draw schematic diagrams and generate network reports to display the circuit principle and the report of the link relationship of each component.

(2) Design the printed circuit board and generate the printed circuit board report. For example, generate a variety of reports, such as generating pin reports, circuit board information reports, network state reports, and finally print out the printed circuit diagram.

2. Design steps of circuit schematic diagram:

(1) Set the size and layout of the circuit schematic diagram, take out the required components from the component library and place them on the working plane;

(2) Connect the components according to the design needs, adjust the wiring components;

(3) EMC design of structural cables,

(4) EMC design of PCB

(5) EMC design of principle devices,

(6) circuit board manufacturing and function debugging
