Reverse engineering of printed circuit boards

　　Reverse engineering of printed circuit boards (PCBs) is a complex but feasible process that allows engineers to extract design details from existing hardware. This process is particularly valuable for understanding and replicating complex electronic systems. It not only involves the physical aspect of the circuit board, but also includes in-depth analysis of its electrical characteristics and functions.

　　In practice, this may include using professional software tools to parse and reconstruct the design files of the circuit board. These tools can help engineers quickly and accurately capture and record various details of circuit boards, including component positions, network connections, and stacked structures. Through this process, one can effectively learn and draw on the advantages of existing designs, and innovate on this basis.
