Preface: This article is connected to the last assignment (using Altium Designer software to draw a circuit schematic diagram of the smallest system of stm32)
One, the addition of PCB project
Add the PCB project on top of the previous schematic.
Add PCB to the project.
Save.
Import the schematic to the PCB.
After the change is made, the following figure:
Then you can see the general figure after the import:
Two, PCB drawing
layout
After selecting all the components, click in the toolbar as shown in the figure to
get the following figure.
Select the pin header to plan
the block diagram. Put the origin into the board
. The board shape after the plan. The
shortcut key N, hide the connection line
layout as shown in the figure. There may be a problem: (Y2 cannot be added)
Let’s modify the rules here
The layout is completed as shown in the figure:
Automatic routing
Auto-wiring rule change:
Use the rule wizard to add a rule and select a network after
selecting width Constraint
next . When the priority of
5v
is selected , the priority is automatically set to the highest, so don’t care. The
aperture setting is shown in the figure.
After modification, apply it
and then slightly modify it.
Copper-clad
Click on the picture to pour copper (select the entire board)
and then select GND
in Net and modify
it in the rules. You can see that there will be some errors
Here we re-lay all the copper and re
-lay as shown in the figure:
the rules that may need to be changed later
Rule check
You can see that I have three errors here.
Double-click the error and we can zoom in on the error and then modify
it. After the modification is completed, we can see that the error is zero.
Add logo
Use drawing software to draw by yourself or add a picture you want
when saving, choose to save as a BMP picture (monochrome bitmap)
Download the logo script

Extract code: h8lz
Search run in AD, click to run the script,
select the downloaded script,
click LOAD to
select Top Overlay, and then click Convent to
select all, Ctrl+ C to copy
Ctrl+V to copy
Three, generate BOM table and network table
Generate BOM
Select as shown in the report and
click export
Generate netlist
Click as shown:
Four, output as Gerber light painting file
Check the
other unchanged, the generated Gerber light drawing file is as shown in the figure:
