esd mat grounding introduction and detection methods
Anti-static esd mat grounding are mainly made of antistatic (conductive) static materials and dissipative electrostatic materials made of synthetic rubber. The color surface is matt and the astigmatism rate is above 95%. The main features are shockproof and anti-fatigue functions. People standing above can automatically adjust the strength of each section of the human body to reduce the body fatigue.
Static parameters: blue surface resistance ≤ 108Ω, black bottom resistance ≤ 105Ω, volume resistance ≤ 107Ωcm, anti-static life of not less than two years, flame retardancy ≤ 10s.
ESD mat grounding are mainly used for floor laying on the production floor, under the pipeline console, etc., and can meet the needs of different conditions and different environments. Has a good electrostatic discharge effect of ESD.
esd mat grounding are tested in the same way. The surface resistance and ground system resistance are mainly tested.
Randomly selected test points, each test pad/mat shall not be less than 3 test points for each test item, averaged.
Test Methods for esd mat roll:
In accordance with the surface resistance test method test bench mat, mat surface resistance;
As shown in Figure 19-a, use a megohm meter to test the workbench facing the wrist strap jack resistance;
