How to confirm the effect of anti-static ball to eliminate static electricity?
According to the ESD20.20 specification, the grounding in the factory and the grounding of the power supply are the same line. Of course, auxiliary grounding can also be used, but the resistance between the auxiliary grounding point and the main grounding point is required to be less than 25 ohms. As for how to determine the effect of eliminating static electricity, there are many methods. The simplest method is to use a voltmeter to test. One of the methods is to test the walking voltage of the human body (a brief introduction in my article), because the human body is not charged. If the method is completely eliminated, even if it is eliminated, it will be generated. Generally speaking, according to physical knowledge, high electric potential flows to low electric potential. If grounded, the static voltage generated by the human body will definitely be conducted. If you want to always check the static value of the human body, this is not available in the market as far as I know, maybe in the laboratory, because the economic value is not great.
