Human body grounding tester test function
In the daily electronics production site, there are often feedbacks that the static voltage on the employees in the workshop is very high. I don't know where the problem is. How can the static electricity on the human body be removed? ANSI/ESD S20.20 stipulates that the resistance of the floor system is less than 1-109Ω, and the electrification voltage is less than 100V peak when people wear anti-static shoes while walking on the floor. The anti-static wrist strap must be used by people who operate the SSD. When using the wrist strap, what should theoretically be a good contact between the wrist strap and the human wrist, the ground connection wire and the ground wire, the wire resistance is 0.8*106Ω; the ground resistance when wearing is less than 3.5* 107Ω. When using a wrist strap, make sure that the grounding must be firm and the contact resistance is small. The diameter of the grounding metal core wire of the wrist strap should be greater than 1.5 mm2, and the elastic band must contain conductive wires.
To do a good job of human body electrostatic protection, we must go through strict technical checks. At present, the most used by customers is the installation of a comprehensive human body electrostatic detector with an access control system at the door of the workshop. Only when the electrostatic protection reaches the standard, the barrier will open the door to allow employees to enter the workshop. How to choose a human grounding tester suitable for workshop use?
