Basic operation of drawing PCB board with AItium designer

1. Generate BOM table and network table through schematic diagram

1 、 GOOD 表

2. Grid table

Second, create a PCB project file

Three, add packaging

The PCB board is the physical product that we see from the schematic diagram. Therefore, to draw the PCB, you must first add the package of each component. The step is to select the corresponding device and find the corresponding component package in the PCB library.

Fourth, import the package to the PCB

Note: You must save the PCB before you can connect to the following operations. If you


find that there is no problem, then click to

join. After successfully joining, you will find the imported components in the PCB window

Five, layout

1. Select the appropriate area size to place these components

For convenience, first select all the components and arrange them around the board.


Check the area you want and select it to plan the shape of the board.

2. Put the components evenly into the area for layout

First, consider the distribution of large components. Due to the limited space, the distribution of large components must be planned first to prevent insufficient space. Then, because the PCB has two sides, the bottom and the top, the PCB is painted part by part, and one part has large components and small components. First place the large components on the top layer, and the small components can be While placing it, press the L key (English input method) to change to the bottom layer mode, and place it on the bottom layer. As long as there is no green between the components, it means that there is no effect.

Six, wiring

1. Modify the rules

When wiring, we will encounter a problem. When we are wiring, we will receive an error of less than 10mil between the two pins of the chip, which makes it impossible for us to wire.

Since the current of the wire connected to the power supply 5V is relatively large, it is necessary to separately set the 5V line to be wider and




keep the high priority.

Modify the required value.

In addition, the drilling hole is large by default, and it needs to be set smaller.

2. Automatic wiring

Seven, copper coating

1. The top layer of copper

Use the following tool to select the entire board to automatically pour copper.


Copper ground, remove dead copper and re-pour copper.
Select only the copper pour area,

select attributes, and



re-pour copper.

2. The bottom layer of copper

Select the top layer copper-clad domain, copy and paste it in the original position, select the attribute and adjust it to the lower layer.

Shortcut key: press the * key on the small keyboard to switch between the bottom layer and the top layer mode

Eight, electrical rules inspection

The final PCB board after the last modification of the error

9. Partial revision methods with hundreds of errors

I made 308 errors and 300 of them can be fixed by modifying some rules

. Set the parameters in the above rules to 6, 0, 0, 0.

The remaining errors are found through the massage first. Generally, there is no perforation, which leads to no way to connect the top layer and the bottom layer or the line distribution is too dense. Re-cladding copper should be able to solve it.

X. PCB diagram output as Gerber light drawing file

Check everything you need and


finally click OK to

export the drill holes . All the gerber files can be seen in the output folder of the project file with

all the default settings below.
