When we redraw Printed Circuit Board Ground Gerber Layer, the signal line crosses the gap between the two grounds. What is the return path of the signal current? Assume that the two grounds that are divided are connected together somewhere (usually in a certain position) single point connection, in this case, the ground current will…
How to Relayout Circuit Board Digital and Analog Ground to make the Printed circuit board has a better performance after manufacturing, first step is to reverse engineering printed circuit board and extract original layout drawing and netlist from it; Before redesigning pcb board layout for a better emc performance, you must understand the two basic…
Reverse Engineering PCB Board to Divide Digital Ground and Analog Ground is a necessary job because although they are connected, but the distance (circuitry wire) is long, it will be different. through clone printed circuit board layout netlist and extract schematic we can redesign the PCB design drawing; The same copper wire, the voltage at…
Reverse Engineering Multi-layer Circuit Board CAD File Principle involve many aspects, including basic principles, anti-interference, electromagnetic compatibility, safety protection, and so on. For these aspects, especially in high-frequency circuits (especially in microwave-level high-frequency circuit board reverse engineering), the lack of relevant concepts often leads to the failure of the entire R&D project. Many people still…
Reverse Engineering Microwave level high frequency PCB Board design has become quite common in the PCB card cloning industry. The PCB layout design cloning principle for microwave-grade high-frequency circuits was chosen because it has broad guiding significance and is currently a popular high-tech application technology. The transition from the microwave circuit PCB design concept to…
Sometimes the purpose of reverse engineering PCB board not only to cloning original electronic circuit board, but also want to further increase the function, which directly increases the difficulty on the PCB layout design. If you increase it through the schematic part, then things will be much simpler, that is one of the main reason…
Manufacturing Circuit Board According to Reverse Engineering PCB Gerber File is a reverse order of PCB design to production, Through reverse engineering printed circuit board, The physical electronic circuit board is converted into the electronic file of the required circuit board diagram which include Gerber file, CAD file, layout scheme and BOM list, then the…
When we Cloning Electronic PCB Board Gerber File, the accuracy is the most important thing to be concerned, since the circuit board reproduction success will greatly depends on it, as a result of that, we will have chance to make errors in the process of reverse engineering PCB board, There are two main possibilities: 1,…
Copying Printed Circuit Board Layout Scheme according to the circuit board data colleted through reverse engineering, the specific operations are as follows: (1) Open the reverse engineering pcb board software, the reverse engineering circuit board software used in this example is Quick-Pcb (multilayer board can be copied, the line width is greater than 0mil), click…
Copy Electronic Circuit Board CAD File is a process to transfer the circuitry pattern of PCB board from scanned pictures to the real CAD file, this part will copy the board according to below Figure, the specific operations are as follows: (1) Open the reverse engineering printed circuit board software, the PCB board copying software…
