EMC Analysis of PCB Board Schematic Cloning mainly considers the following aspects:
1) Frequency: Where does the problem occur in the frequency spectrum?
2) Amplitude: How strong is the energy level, and what is the potential for harmful effects?
3) Time: Is the problem a continuous periodic signal or is it only within a certain operating cycle?
4) Impedance: What is the impedance of the source and receiver units when reverse engineering PCB board? What is the impedance of the transmission medium between the two?

5) Size: What is the physical size of the emitting device that caused the radiation to appear?
A key point to solve the problem of electromagnetic radiation interference in PCB Board Cloning is to find out which interference source the frequency and amplitude of electromagnetic radiation originate from, and then take measures to limit the electromagnetic radiation generated by the interference source within a certain range.

The radiation on the automotive electronics circuit board is mainly generated from two sources: one is the PCB trace, the other is the I/O cable, and the cable occupies an important position.
