What are the anti-static indexes and standards?
I believe that many friends do not understand the indicators and standards of the anti-static index. The indicators and standards of the anti-static index are strictly stipulated. In the actual production process, we need to have a basic understanding and understanding of the anti-static index, so that we can Wear protective equipment correctly during production operations to ensure your own safety, product qualification rate, and enterprise production efficiency. So what are the indicators of anti-static index?
1. The ground resistance of the anti-static ground electrode is usually less than 10Ω.
2. The surface resistance value of the ground or floor mat should be between 105-1010Ω, and its friction voltage value should be less than 100V.
3. The resistance value of the wall is generally required to be between 5×104~109Ω.
4. The surface resistance value of the work surface or pad should be maintained between 106 and 109Ω, and the friction voltage should be less than 100V; the system resistance to the ground should be within the range of 106-108Ω.
5. The resistance requirement of the work chair facing the casters is between 106 and 108, and cannot exceed this specified value.
6. The friction voltage of anti-static overalls, dust-free caps, and anti-static gloves should be less than 300V, and the friction voltage of anti-static shoe soles should be less than 100V.
7. The resistance of the wrist strap connection cable is 1M Ω; when wearing the wrist strap, the system resistance should be between 1-10M Ω. Heel strap (shoe bundle) system resistance 0.5× 105～108Ω.
8. The resistance of the logistics vehicle platform facing the wheel system is 106-109Ω.
9. The surface resistance value of logistics transfer equipment such as material boxes, turnover boxes, and PCB racks is 103~108Ω; the friction voltage is less than 100V.
10. The friction voltage of packaging bags and boxes should be less than 100V.
11. The comprehensive resistance of the human body is 107～108Ω.
