How do you make a simple circuit diagram?

The following are the steps to make a simple PCB circuit diagram:

1. Circuit design planning:

Clarify the purpose and performance of the PCB, and determine parameters such as power supply voltage, current, and signal frequency.

Select components based on function, and check the data sheet to determine the package, pins, and electrical parameters.

2. Draw a schematic:

Select EDA software (such as Altium Designer, Eagle, KiCad, etc.) or draw it manually with pencil and graph paper (need to be converted to electronic format).

In the software, find symbols from the component library and drag and drop them, or manually draw component symbols according to the standard and mark the names.

Use the software to connect component pins with a wiring tool, and manually use a ruler and pencil to connect. Pay attention to the connection point representation and neat lines.

Mark component parameters, names, packages, and network names or signal names.

3. PCB layout:

Create a new PCB file and import schematic information.

Determine the PCB size and shape according to requirements, such as selecting a 50mm×50mm square.

Drag and drop components from the library into the board frame, divide them according to function, and pay attention to the spacing that is conducive to welding and heat dissipation, such as separating high-power components.

4. PCB wiring:

Set wiring rules according to circuit properties and component parameters, such as power line width 1-2mm, signal line width 0.2-0.5mm, and spacing not less than 0.2mm.

Manual wiring (using software wiring tools to draw lines according to connection relationships and control the direction), automatic wiring (manual adjustment after the software automatically completes) or a combination of the two.

Check whether the wiring is compliant, whether there are short circuits or open circuits, optimize the wiring of key signals, and reduce interference.

5. Design inspection and output files:

Use the software DRC function to check the PCB design and modify the problems according to the prompts.

Generate Gerber files (for PCB manufacturing) and BOM files (list component information). Different software has different generation methods, such as “File”-“Fabrication Outputs” in Altium Designer to generate Gerber, and “Reports”-“Bill of Materials” to generate BOM.
