This includes preparing catalogs and schematics. Before PCB design, first prepare the schematic SCH component library and PCB component package library. The PCB component packaging library should preferably be established by engineers according to the standard size data of the selected components.
In principle, the component packaging library of PC shall be established first, and then the schematic SCH component library shall be established. PCB component packaging library has high requirements, which directly affects the installation of PCB; The schematic SCH component library is relatively loose, but pay attention to defining the pin attributes and the corresponding relationship with PCB component packaging library.
PCB structure design
According to the determined size of the circuit board and various mechanical positioning, draw the PCB frame in the PCB design environment, and place the required connectors, keys/switches, screw holes, assembly holes, etc. according to the positioning requirements. Fully consider and determine the wiring area and non wiring area (such as how much area around the screw hole belongs to the non wiring area).
PCB layout design
PCB layout design is the first important process in the whole PCB design process. The more complex the PCB is, the better the layout will directly affect the difficulty of later wiring.
The layout design depends on the basic circuit skills and rich design experience of the circuit board designer, which is a high level requirement for the circuit board designer. The junior PCB designer has little experience and is suitable for small module layout design or PCB layout design task with low difficulty.
