Learn to use AD20 by drawing snowflake lights
1. Create a project and name the project
2. Add a new schematic (library) and PCB (library) to the project
(corresponding to 1, 2, 5, 6 in the figure)
Note: You can draw the schematic library and PCB library by yourself, But it’s better not to draw it yourself.
3. Draw the schematic diagram
1) led series resistance
2) switch + type-c
3) TPS7350 five-volt power supply module
4. Import package
tool-package manager-add-accept creation-execute Change Only
when the component appears, it can be considered as a successful addition, and then the PCB can be exported. Figure
5. After importing the package, generate the PCB
design-update-execute the change. It
appears as shown in the figure.
6. Organize the components and place them in modules according to the schematic
7. Use keep-out Layer drawing board shape (shortcut key P+L)
design-board shape-defined according to the selected object.
Because it is a gadget, you can draw the shape you want.
8. Place the components on the board neatly and orderly, and you can put it On the top layer or bottom layer, the placement is beautiful and conducive to the best wiring
9. Modify the rules (design-rules-clearance/width)
1) change the line width 10mile-80mile
2) the distance between the component and the line 6mile (mostly)
3) You can modify when you just import the pcb.
10. Wiring
1) Shortcut key W
2) The lines on the top and bottom layers can cross, but the same layer can’t, so when placing components, pay attention to whether they are placed Conducive to wiring
3) The signal line width can be smaller, usually 15mile-20mile;
gnd and vcc line width is larger, about 50-80mile range
11.
Copper coating 1) Place – copper-lay – tab key – select GND network
2)
The steps of laying copper on the top and bottom layers of the circuit board are basically completed, if you think the circuit board is too monotonous, you can also add silk screen to the board (Logo, text, picture, etc.) Now let’s introduce the way to add logo.
12. Silk screen
1) Find a picture you like and convert the file format to bmp type
2) File-Run script-Select script file-Select The layer to be placed is usually the silk screen layer.
3) After exporting, the joint is generated.
4) Copying to the drawn pcb file is completed.
Note: There is a script file when running the script. Just go to the silk screen layer.
13. Switch to 3D mode and see the effect. The
first release, please advise!
