Check CT Scanner Cloned PCB Board Function

Check CT Scanner Cloned PCB Board Function needs to followed below points:

1. Whether the digital circuit and analog circuit components of the digital-analog hybrid ct scanner cloned pcb board have been separated in the layout of original printed circuit board, and whether the signal flow is reasonable;

2. A/D converter placement across analog-to-digital partitions;

3. Whether the clock device layout is reasonable;

4. Is the layout of high-speed signal printed circuit boards design reasonable?

5. Whether the terminating device has been properly placed (source matching string resistance should be placed at the driving end of the signal; middle matching string resistance should be placed in the middle position; terminal matching string resistance should be placed at the receiving end of the signal);

6. Whether the number and location of decoupling capacitors in the IC device are reasonable;

7. The signal lines use planes of different levels as the reference plane. When crossing the plane division area, whether the connection capacitance between the reference planes is close to the signal routing area;

8. Whether the layout of the protection circuit is reasonable and whether it is conducive to division;

9. Whether the fuse of the single pcb board power supply is placed near the connector and there are no circuit components in front of it;

10. Confirm that the circuits of strong signal and weak signal (with a power difference of 30dB) are laid out separately;

11. Whether to place devices that may affect EMC experiments according to reverse engineering pcb board layout diagram guidelines or reference to successful experience. For example: the reset circuit of the panel should be slightly closer to the reset button;
