1. The first choice to create a new project. Method: It is necessary to start the Protel99se software, and then create a new engineering project by ordering the menu. The project is best named after its own name or school number to choose the preservation path.
2. Create a new schematic map editor and print circuit board editor. Methods: Create a new schematic graph editor and print circuit board editor in the document manager), and then enter the scratch of the drawer to set the drawer.
circuit board
3. Place the components and draw the line. Methods: Select components in the gallery in the gallery according to the given circuit diagram and place them in the schematic editor, then layout the component, and finally save and save it.
4. Pay attention to the steps of the CAD drawing PCB board circuit diagram, use the command of the wire when drawing the wire; the command of the bus should be used when drawing the bus; Function, this is also the basic point for students to master.
5. Update the device running number, and perform ERC to detect the painted circuit schematic diagram. This step also needs to choose the correct command for operation.
6. Package the components. Methods: Open the printed circuit board editor that has been established in advance before packaging, and find the corresponding packaging in the component library. Common component packaging: resistance, non -polar capacitors, polar capacitors, diodes, triode, and dual -column direct -inserted components are prefixed by DIP, and the packaging of the interface device is based on SIP.
7. Generate network tables. How to do this step? Boyuan Electronic designer said that the CreatenetList command can be created by the DESIGN drop -down menu or click the mouse to right -click to select the CreatenetList command.
