PCB Design Procedures:
1, Use Schematic design tool to draw it then generate corresponded net-list, of course in the special circumstance such as a simple PCB board, there is no need to carry out the schematic drawing designing if the net-list has existed, enter directly into the PCB design system, in the system can pick up the component footprint directly to generate net-list manually.
2, Change the netlist manually, define the fixed pin on the components which has been designed on the soldering pad of schematic diagram, for those pins without any physical connection can lead to the ground or protection ground, etc. categorize the pins with different names with schematic and PCB footprint align with the PCB library especially the diode, transistor, etc.
use la herramienta de diseño esquemático para dibujarlo y luego genere la lista de red correspondiente, por supuesto, en circunstancias especiales, como una placa de PCB simple, no es necesario realizar el diseño de dibujo esquemático si la lista de redes ha existido, ingrese directamente en el sistema de diseño de PCB, en el sistema puede recoger la huella del componente directamente para generar la lista de red manualmente
