PCB board design needs to provide information:

1. Schematic: A complete electronic document format that can produce a correct netlist (netlist);

2. Mechanical size: provide the specific position and direction identification of the positioning device, and the identification of the specific height limit position area;

3. BOM list: mainly to determine and check the specified package information of the device on the schematic;

4. Wiring Guidelines: Descriptions of specific signal specific requirements, as well as design requirements for impedance, lamination, etc.

The basic design flow of PCB board design is as follows:

Pre-preparation -> PCB structure design -> PCB layout -> wiring -> wiring optimization and silk screen -> network and DRC inspection and structural inspection -> plate making.
