Anti-static Equipment and Facilities at the Production Sites of Electronics Factory and Semiconductor Factory
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.
7. Personnel entering the work area must wear anti-static work shoes. Persons wearing ordinary shoes should use conductive shoe harnesses, anti-static shoe covers or heel straps.
9. The conveyor belts and drive shafts used on the production line should be equipped with anti-static grounding brushes and poles.
10. Ion wind static eliminator can be used on the surface of the conveyor belt.
11. Assembling fixtures, testing fixtures, welding tools, various instruments, etc. used in the production site should be provided with a good grounding wire.
12. An anti-static test bench should be installed at the entrance of the production site. Everyone who enters the production site should undergo an anti-static test. Only after passing the test can enter the site.
