PCB Design Steps

1. Understand the electrical parameters
Before starting PCB design, you should understand the electrical parameters of the system, including:

Maximum current
Voltage
Signal Type
Capacitance Limits
impedance characteristic
Shielding Considerations
Type and location of circuit components and connectors
Detailed network cable list and schematic
2. Create a schematic diagram
The first step is always to create a schematic, which refers to the design of the electrical level of the board's purpose and function.

3. Create PCB layout
Use tools to design schematics.

4, Design PCB Stacks
Impedance needs to be considered early in the PCB design phase, and the stack is very important in the PCB design phase.

5. Define design rules and requirements
Generally, the company will have its own set of design rules and layout requirements, which can avoid repeated modification of PCB design.

6. Placement of components
In order to prevent electrical noise in the circuit, some components will have more stringent requirements.

7. Insert drill hole
Here, it is mainly driven by the components and connections, that is, the connection with the underlying drilling.

8. Wiring
After preventing the components and drilling holes, you can start wiring.

9. Add labels and identifiers
Add labels, identifiers, labels, or reference designators to help show the location of specific components on the board.
