Instructables
PCB reverse engineering, also known as PCB cloning 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, extraction of 3-dimensional model data on a variet of electronic products, compile the components list assembled on the PCB circuit board as well as individual data sheets on each component where available, decrypt microcontroller on the circuit board, crack encrypted IC on the PCB, moreover, inverse assemble the firmware of PCB circuit board and etc, a whole set of PCB reverse engineering technology.

Step 1: Clean the surface of PCB

Picture of Clean the surface of PCB
There is a 4 layer PCB need to being reversed engineering, all the components assembled on the surface have already been removed by hand-held soldering iron and air pressure gun, during this stage operator must be aware of components especially for those components with fine lead and high unit price delicate IC, after that, pcb board surface must be cleaned by washer water Washer which main ingredients are chlorinated solvents, buffer, corrosion inhibitor, antioxidant, surface active agent composition. Features of washer water is Low toxicity, no risk of explosion, the maximum allowable concentration in air 100PPM.
