1. First, we open the software Altium Designer. Create a project file, and then create a schematic file under the project file.
2. Find the menu bar on the right to add components. When you find it, double-click it and drag the component to the editing area.
3. If there are no components in the library, you have been importing other component libraries prepared in advance for a long time.
4. After importing, in the menu bar above, find the line drawing sign to draw lines.
5. After painting, you should save it. Find the file at the top left.
6. After finding it, save the project file first, then save the schematic file, and that's all.
The schematic diagram, as its name implies, is a diagram showing the connection principle between devices on the circuit board. Schematic diagram plays a very important role in empirical research such as scheme development, and its control is also related to the quality and even life of the whole project.
Extending from the schematic diagram will involve PCB layout, that is, PCB wiring. Of course, this wiring is done according to the schematic diagram. By analyzing the schematic diagram and other conditions of the circuit board, the designer can determine the position of the device and the number of layers of the circuit board.
In the field of reverse research, reverse research institutions such as Taidou Technology and Shenzhen Zhiwei Technology generally clone PCB files perfectly by scanning and tracing lines in order to help customers conduct reverse research.
The circuit on the circuit board is described clearly and accurately, and then the schematic diagram of the circuit board is deduced according to the described pin connection relationship, so that the designer's design ideas can be learned and applied or the circuit board can be maintained in this way without the original schematic diagram.
