Clone PCB Board Schematic Diagram has a unique system to place and arrange the locations of electrical components and the connection relationship among them. Since there are some tiny components in the PCB board scanning image that are not visible or that the components in the image are visible, causing the types of these components to be unknown.
Therefore, it is impossible to select the standard component symbol map; secondly, due to the variety of types in the component library, the operation of component selection it is complicated.
At present, only the description of electrical connection among components soldered on the PCB board is drawn, which gives people a more intuitive feeling, but actually it is not the final version of schematic diagram. Therefore, it is necessary to design a component symbol library for component connection processing according to the characteristics of PCB reverse engineering.
In the PCB board reverse engineering system, the method used is to represent a type of component in a symbolic diagram. The classification is based on the number of pins. The reason is that the component connection process is the relationship between the component pins and the solder joints.
Even if the component types are different, it does not matter here, because it will ultimately be judged based on the input component identification and component packaging. When Clone PCB Board Schematic Diagram, the system will search and analyze Protel component library based on the component package and generates the corresponding standard component graphic symbol.
