Electronic PCB Wiring Card Reverse Engineering
Electronic PCB Wiring Card Reverse Engineering is one of the most important aspects of getting the old printed circuit board reproduction, however, since the electronic PCB bard delayer process will refer to sandpaper scrubbing the copper foil layer, and circuit track pattern description, seldom designer engineers are willing to participate this activity.
Even some of the designer believe that printed circuit board reverse engineering is not a technical work, even a preliminary designer with very few professional training can complete this job. This viewpoint has a certain level of popularity, however, just as most of the other jobs, reverse engineering electronic circuit board has possessed some technology. And if the designer can master these technologies, they can save a great amount of time and energy.
1, the concept of PCB circuit board reverse engineering:
Electronic PCB card reverse engineering is a technical process which can help to obtain the schematic diagram and PCB layout through a physical PCB board sample. The purpose of PCB card cloning is for the development in the later stage. Later stage includes the electronic components installation, test in deep level, debug the circuit, etc.
2, the process of PCB board layout redesign:
1> Dismantle all of the components from Electronic pcb wiring card;
2> Scanning the original bare electronic pcb wiring card and get the drawing file;
3> Scrub the surface layer to obtain the internal layer;
4> Scanning the internal layer to obtain the layout drawing;
5> Repeat from step 2 to step 4 till all of the layers drawing can be scanned;
6> Use the specific software to convert the drawing file into electrical connection file, so call circuit board layout, and if there is any proper software, then designer need to scan all of the drawing again;
7> Check all of the steps and ensure the correctiveness;
