Talking about the anti-static facilities in the production workshop
Static electricity is the phenomenon of triboelectricity generated when two objects rub against each other. When it accumulates to a certain extent, spark discharge occurs. This phenomenon is closely related to life and production, and often brings some inconvenience or harm. It is especially important in the production workshop. It is necessary to suppress the accumulation of static charge, and quickly, safely and effectively eliminate the static charge that has been generated.
The following introduces the necessary anti-static facilities in the production workshop, other than the anti-static liquid we know about.
1. Static safety workbench: It is composed of workbench, anti-static table mat, wrist strap connector and grounding wire.
2. There should be more than two wrist strap joints on the anti-static table mat, one for operators and one for technicians and inspectors. 3. It is not allowed to stack plastic boxes, rubber, cardboard, glass and other debris that are prone to static electricity on the electrostatic safety workbench. The drawings and materials should be placed in an anti-static document bag.
4. Anti-static wrist strap: People who directly touch electrostatic sensitive devices must wear an anti-static wrist strap. The wrist strap should be in good contact with the human skin, and the resistance of the wrist strap system to the ground should be 1MΩ.
5. Anti-static containers: The component holding bags, turnover boxes, PCB loading and unloading racks in the production site should be equipped with electrostatic protection. Metal and ordinary containers are not allowed, and all containers must be grounded.
6. Anti-static work clothes: People who enter the static work area and those who come into contact with SMD components must wear anti-static work clothes, especially in dry environments where the relative humidity is less than 50% (such as winter). Work clothes fabrics should meet the relevant national standards.
