To be a person to have a big picture, PCB design is the same. Before starting a PCB project, designers should understand the overall flow of the project from start to finish, as well as the key points that need to be paid special attention to during the project’s operation. Next, let’s share the process of PCB project.
After the structure drawing is imported, special attention should be paid to the size of the screw holes and some positioning holes, the forbidden cloth area of the device and the wiring, the height limit area, and the position of the connector.
In addition to the limitation of structure, the basic idea of the layout is to combine the signal flow direction and the power flow direction to the layout.
Some of the rules need to be guided by pre-stimulation, such as line length, impedance, topology, stack structure, etc.
Such as line impedance, reference surface continuity, EMC, SI/PI, DFM, etc.
