This article describes the correct connection of the filter capacitor in the PCB design. In many PCB designs, I found that many of my friends have problems with the filter capacitor wiring, so I have a few pictures to explain, I hope to help everyone. The figure below is a wrong filter capacitor connection. The power supply should be directly from the capacitor to the IC. The filtering effect will be good. The figure below is the correct connection. According to this method, the filtering effect will be much better. If everyone thinks this is not good, the following figure is correct. You can also find that the following processing methods are also used in some PCB designs.
