Reverse Engineering Circuit Board Schematic Diagram needs to identify the PCB board’s circuit pattern dissipation and layout PCB circuit pattern logically:
For distinguish of ground plane, power supply circuit and signal circuit, also require engineer to have related power supply, circuit connection, PCB board layout and PCB layout reverse engineering rules. How to distinguish these different kinds of circuit can rely on component connection situation, copper thickness and feature of electronic product.
Reverse Engineering Circuit Board Schematic Diagram needs to identify the PCB board’s circuit pattern dissipation and layout PCB circuit pattern logically
During the process of printed circuit board gerber file relayout, in order to avoid the cross line, large bulks of ground signal can be applied on the ground plane, different circuit can use different colors to help distinguish one another, also specified symbol can use on specified components, can even separate unit circuit and draw them. And finally can integrate them together.
From other side, please remember that same kind of electronic product can be similar to a certain extent, engineer should accumulate more experience and can take them as reference to reverse engineering other PCB board schematic diagram.

Checking and Optimization:
Whole process of Reverse Engineering Circuit Board Schematic Diagram finish only after checking and testing done and approve pass, for nominal value of those distribution parameter sensitive components of PCB need to check and optimizing, according to printed circuit board layout redesign process, compare the PCB wiring diagram with design file to ensure the accuracy and completeness.
