A high-speed digital signal PCB board reverse engineering method based on signal integrity computer analysis. In this reverse engineering method, the signal transmission model of the PCB board level is first established for all high-speed digital signals, and then the solution space of the reverse engineering is found through the calculation and analysis of the…
In many CAD systems, High Speed Printed Circuit Board Gerber File Cloning is determined by the network system. The mesh is too dense, although the path is increased, but the stepping is too small, the data volume of the field is too large, which inevitably has higher requirements on the storage space of the device,…
Many PCB card cloning engineers typically consider the issue of anti-static discharge (ESD) when the PCB card enters production especially for the multilayer PCB board reverse engineering. If the electronic PCB card fails the anti-static release test, they will work overtime to find a solution that will not damage the original design. However, the final…
PCB Cloning Circuitry Design Skill requires pay attention on the circuitry layout, annular ring hole, soldering pads, drilling hole, etc which should be suitable for manufacturing: The lines are exquisite: the conditions are wide and the lines are never made fine; the high-voltage and high-frequency lines should be smooth, no sharp chamfers, and corners should…
PCB Board Reverse Engineering Experience can be summarized as below points: Have a reasonable direction: such as input / output, AC / DC, strong / weak signal, high frequency / low frequency, high pressure / low voltage, etc., their direction should be linear (or separated), not mutually blend. Its purpose is to prevent mutual interference.…
Many PCB cards are no longer single-function circuits (digital or analog circuits), but rather a mixture of digital and analog circuits. Therefore, it is necessary to consider the mutual interference between them when Reverse Engineering PCB Card Digital Circuits & Analog Circuits, especially the noise interference on the ground. The frequency of the digital circuit…
Even if the circuitry pattern and schematic diagram in the entire process of Reverse Engineering Circuit Card Power & Ground is completed well, the interference caused by the inconsistency of the power supply and the ground line may degrade the performance of the product, and sometimes even affect the success rate of the product. Therefore,…
In the PCB Board Reverse Engineering, Circuitry Layout is an important step to complete the product design. It can be said that the previous preparation work is done for it. In the whole PCB board, the circuitry design process is the highest, the trick is the finest, and the workload is the largest. The PCB…
Many people see the chip-scale BGA package as a viable solution to the space constraints required by high density Printed circuit board on the portable electronics, while meeting the higher functionality and performance requirements of these products. Cloning High Density Printed Circuit Board for portable products should be an assembly process. Performance and reliability are…
