PCB Board Reverse Engineering Critical Technique Analysis points are as follows:
- Provide reference picture posting function and network connection check tool to conveniently and effectively reduce the probability of wrong PCB layout drawing, gerber file and schematic diagram;
- Real-time check of electrical elements, convenient fault judgment and maintenance operation, and instant PCB reverse engineering capability;
- Directly implement electronic equipment data system management and auxiliary operations;
- The symbol system is instantly converted, and the classification form of the PCB board scanning graphic is displayed and edited;
- Establish a component library, a lattice symbol, and a combination symbol library;
- The PCB schematic diagram is automatically reconstructed.
Refers to the double side printed circuit board, the component side and soldering side, are called A and B faces respectively (the welding components include integrated circuits, resistor, capacitor, inductors, switch and terminals may exist on both sides), and the passive or negative components on each side can be classified into a point set and a line set. The point set contains elements such as pads, half size holes, vias, etc. The line set contains elements such as wires, jumpers, and bus bars, etc.
Whether manual or automatic routing, engineer need to first determine the physical location of the various elements, and assign each element to a logical name and number. After the above positioning is completed, the wire connection is implemented. The principle is to pull out the connecting line with a dot element and give the direction of the connecting line. In the above manner, the physical connection of the PCB board being reverse engineered can be realized.
