The problem to be solved by component connection processing including the creation of a component graphics library, the design of component types, and the connection processing of component pins.
Component connecting processing refers to the connection between the component’s pins and solder joints. Component connection processing and generation of schematic diagrams from PCB Layout drawing and Gerber file must first establish the corresponding component library, due to the great variety of components, the establishment and maintenance will take a great deal of time and energy;
Therefore, how to take advantage of component libraries from Protel. The various symbology in the component library makes the operation complicated in the process of component connecting processing, and tiny or other unknown components appear in the scanning image acquired from PCB reverse engineering, and such components can not be represented by component symbols in the component library.
Therefore, it is necessary to design various component symbols suitable for component connecting processing according to the characteristics of target PCB which has been reverse engineered, and design the component connection processing algorithm according to various component graphic symbols.
