電磁兼容性是指電子設備在各種電磁環(huán)境中仍能夠協調、有效地進行工作的能力。目的是使電子設備既能抑制各種外來的干擾，使電子設備在特定的電磁環(huán)境中能夠正常工作，同時又能減少電子設備本身對其它電子設備的電磁干擾。

1、選擇合理的導線寬度由于瞬變電流在PCB電路板印制線條上所產生的沖擊干擾主要是由印制導線的電感成分造成的，因此應盡量減小印制導線的電感量。

2、采用正確的布線策略采用平等走線可以減少導線電感，但導線之間的互感和分布電容增加，如果布局允許,最好采用井字形網狀布線結構，具體做法是印制板的一面橫向布線，另-面縱向布線, 然后在交叉孔處用金屬化孔相連。

3、為了抑制PCB電路板導線之間的串擾，在設計布線時應盡量避免長距離的平等走線，盡可能拉開線與線之間的距離，信號線與地線及電源線盡可能不交叉。在-些對干擾+分敏感的信號線之間設置-根接地的印制線， 可以有效地抑制串擾。

電路板主要由焊盤、過孔、安裝孔、導線、元器件、接插件、填充、電氣邊界等組成，各組成部分的主要功能如下:
焊盤:用于焊接元器件引腳的金屬孔。
過孔:有金屬過孔和非金屬過孔，中金屬過孔用于連接各層之間元器件引腳。
安裝孔:用于固定電路板。
導線:于連接元器件弓|腳的電氣網絡銅膜。
接插件:用于電路板之間連接的元器件。
填充:用于地線網絡的敷銅，可以有效的減小阻抗。
電氣邊界:用于確定電路板的尺寸,所有電路板上的元器件都不能超過該邊界。

Electromagnetic compatibility refers to the ability of electronic devices to work harmoniously and effectively in various electromagnetic environments. The purpose is to enable the electronic device to both suppress various external interference, so that the electronic device in a specific
It can work normally in the electromagnetic environment, and at the same time, it can reduce the electromagnetic interference of the electronic equipment itself on other electronic equipment.

1, choose a reasonable wire width because the impact of the transient current on the PCB circuit board printed line is mainly caused by the inductive component of the printed wire, so the printed wire should be minimized
The inductance.

2, using the correct wiring strategy using equal wiring can reduce the inductance of the wire, but the mutual inductance and distributed capacitance between the wires increase, if the layout allows, it is best to use the well pattern network wiring structure, specific
One side of the printed board is wired horizontally, the other side is wired longitudinally, and then connected with metallized holes at the cross holes.

3, in order to suppress the crosstalk between PCB circuit board wires, in the design of wiring should try to avoid long-distance equal wiring, as far as possible to open the distance between the line and the line, signal line and ground and power line
Can not cross. The printed line is set up between the signal lines that are sensitive to interference and can effectively suppress crosstalk.

The circuit board is mainly composed of welding pad, through hole, mounting hole, wire, components, connectors, filling, electrical boundary, etc. The main functions of each component are as follows:
Pad: A metal hole for welding the pin of a component.
Through holes: there are metal through holes and non-metal through holes, and the middle metal through holes are used to connect the component pins between each layer.
Mounting hole: used to secure the circuit board.
Wire: electrical network copper film connected to the | foot of the component bow.
Connector: A component used to connect circuit boards.
Filling: Copper coating for ground wire network can effectively reduce impedance.
Electrical boundary: Used to determine the size of the board, all components on the board can not exceed this boundary.
