No matter how you deliberately design, you will still think that many places can be modified when you finish the design. The general design experience is the time to optimize the wiring is twice the time of the first wiring. After feeling that there is nothing to modify, you can lay copper (Place->polygon Plane). The copper is generally grounded (note the separation of analog ground and digital ground), and power supply may also be required for multilayer boards. When it comes to silk screen printing, be careful not to be blocked by the device or removed by vias and pads. At the same time, face up to the component surface when designing, and the words on the bottom layer should be mirrored to avoid confusion.
First of all, on the premise that the circuit schematic design is correct, the generated PCB network file and the schematic network file are physically connected to the network check, and the design is revised in time according to the output file result to ensure the wiring The correctness of the connection.
After the network check is passed correctly, the PCB design is checked for DRC, and the design is revised in time according to the output file results to ensure the electrical performance of the PCB wiring. Finally, it is necessary to further check and confirm the mechanical installation structure of the PCB.
Before this, it is best to have a review process.
Design is a work that is delicate, meticulous, and must be highly concentrated and thoughtful. Only by being meticulous, striving for perfection, and slowly accumulating experience can a good board be designed.
