pcb restoration, also known as PCB clone or PCB copy, is using reverse engineering technology onto the PCB which was designed and manufactured by others, it is to use PCB related software to copy someone else’s circuit board and then manufacture the circuit board by yourself. This is the tradditional explanation for the PCB reverse engineering. with the pcb reverse engineering technology development, the impact and scope of this industry continues to expand rapidly, and the definition of pcb reverse engineering also extend from the narrow sense that: pcb reverse engineering only refers to extraction of PCB file from electronic circuit board and then restore it for the purpose of PCB cloning or copy; To the wide sense that pcb reverse engineering not only include PCB file extraction, circuit board cloning/copy and other related technical aspect, but also modify PCB file, the shape of the mold for electronic products
