What are the precautions for making PVC boards when testing separation devices?Close1) The wiring of the pins should be shortened as much as possible, and the required components (such as inductors) should be connected as close as possible to the root of the device pins;
2) Layout high-frequency components within a small range of the PCV board and away from other components;
3) Try to achieve a grounding point as much as possible to prevent high-frequency signals from affecting the ground wire;
4) The power terminal of the tested device should have a grounding capacitor to prevent high-frequency signals from interfering with other peripheral components and V/I sources through the power supply;
5) The input and output terminals of the device should not only be grounded with a specified electrolytic capacitor, but also be connected in parallel with a suitable filtering capacitor on the electrolytic capacitor;
6) In special cases, a 1K resistor is connected in series in the SENSE line of the relevant V/I source to reduce the interference of high-frequency signals on the V/I source;
7) The input terminal with threshold measurement is connected to a high-frequency capacitor to ensure the quality of the scanning signal;
8) All capacitors, the closer they are to the device pins, the better, including the ground of the capacitors.
