Human safety issues in the use of anti-static shoes and wristbands
Only from the perspective of anti-static, the smaller the total resistance to ground of the human body, the better, but the minimum value is limited by safety. The resistor can limit the current flowing through the operating body in the event of a power short. The minimum value should not be less than 105Ω, usually the current limiting resistance of the wrist strap is 1MΩ, the minimum resistance of anti-static shoes should not be less than 105Ω, and the maximum should not exceed 109Ω.
