Cloning Printed Circuit Board Gerber File needs to take its dimension into consideration, the size of the printed circuit board must be determined before reverse engineering PCB circuit board, when the size is too large, the printed circuit will increase the impedance due to the long lines, the noise resistance will decrease, and the cost will increase; if it is too small, the heat dissipation is not good, and Nearby lines are susceptible to noise.
If it is a high-frequency board, there are strict restrictions on the length of the wiring. According to the network theory of distribution parameters, the interaction between the high-speed circuit and its connection is a determining factor, and it cannot be ignored in the PCB board layout system redesign. Normally, the power consumption and heat consumption of high-speed circuits are also very large. It should be given enough attention when reverse engineering high-speed printed circuit board layout.
When there are weak signals in the millivolt or even microvolt level on the printed circuit board, special attention should be paid to these signal lines. Small signals are very weak and are very susceptible to interference from other strong signals. of. Otherwise, the signal-to-noise ratio will be greatly reduced, causing useful signals to be overwhelmed by noise.
The debugging of the pcb circuit board should also be taken into consideration.The physical location and isolation of the test point cannot be ignored, because some small signals and high-frequency signals cannot be directly added to the probe for measurement.
