Reverse Engineering PCB Board Anti-Noise

Reverse Engineering PCB Board can radiate the noise in the operation and make it becomes the source of noise: the signal line in the PCB board can transfer them to enclosure through grounding revert and cause resonance, and the radiation will be emitted through enclosure; PCB board signal can convert the signal through its cable after reverse engineering PCB board, and PCB board can also be the source of external source, so in order to decrease the noise from radiation, below actions could be taken:

1, choose the proper components, and in the process attention must be paid on the aging issue for electronic components, and pick up those components on the PCB board with less thermal reaction when reverse engineering PCB board. As for the PCB board with high frequency, should choose the proper microcontrollers and integrated circuit to reduce the radiation. When choosing the logic components, take the noise capacitance limitation into consideration: if only consider the capacitance value then better choose HTL, but if take power consumption into account, then choose CMOS with VDD greater or equal to 15V;

2, multilayer PCB board reverse engineering can help to acquire the reasonable shielding effect: and use the internal layer as power line or grounding line, and seal the power line inside the PCB board with insulation treatment on both side, which can help to make the current flow on top side and bottom side simultaneously without affect each other; and make the internal layer as conductor with large area, and allow great static electrons capacitance among conductors to form the power supply line with low impedance, can effectively prevent the PCB board radiation and noise receipt when REVERSE ENGINEERING PCB board.
