The PCB design process includes multiple stages such as design preparation, circuit design, PCB layout, wiring, processing and manufacturing, and test and verification. The following is the key steps of PCB design analysis.
1. Design preparation stage
Requirements Analysis
Understand the functional requirements of the product and performance indicators, to determine the main functions of the circuit board and the principle of operation.
Selection
Select the appropriate components and devices according to demand, including resistors, capacitors, integrated circuits, connectors, etc..
Design specifications
Develop PCB design specifications and standards, including board thickness, levels, signal specifications, etc..
2. Circuit design stage
Draw circuit schematic
Draw circuit schematic according to product requirements, including component connection relationship and signal flow, etc..
Simulation analysis
use circuit simulation software to simulate and analyze circuit performance, and assess the feasibility and stability of the design scheme.
3. PCB layout stage
Layout planning
According to the circuit schematic diagram, plan the layout location of the components on the circuit board, taking into account the length of the signal lines, power lines, heat dissipation and other factors.
Component placement
Place the components on the circuit board according to the layout planning, considering the spacing and connectivity between components.
4. Wiring stage
Signal line wiring
Connect the signal lines between the components, consider the length of the signal line, width, impedance matching and other factors.
Power line wiring
connect the power supply and ground to ensure that the power line is short and stable to avoid power interference.
Layered wiring
For complex circuits, multi-layer wiring can be used to separate the signal and power lines and improve circuit stability.
5. Processing and manufacturing stage
Generate Gerber file
Generate Gerber file according to the design completion, including component location, line connection and other information.
PCB processing
send the Gerber file to the PCB processing manufacturer for PCB board processing and manufacturing, including printing, etching, piercing and other processes.
6. Test verification stage
Functional testing
Functional testing of the completed PCB board to verify that the circuit meets the design requirements.
Electrical Characteristics Test
Test the electrical characteristics of the PCB board, including impedance, signal transmission performance.
EMC test
Electromagnetic compatibility test to ensure that the PCB board in the electromagnetic environment stable operation.
