Anti-static facilities for electronic products
1. Electrostatic safety workbench a. The electrostatic safety workbench is the basic component of the anti-static work area. It consists of a workbench, an anti-static table mat, a wrist strap connector, and a ground wire. b. There should be no less than two wrist strap joints on the anti-static table mat, one for operators and the other for technicians, inspectors or other personnel. c. When necessary, an ion wind static eliminator should be equipped on the static safety workbench. d. It is not allowed to stack plastic boxes (sheets), rubber, cardboard, glass, etc., which are prone to static electricity, on the electrostatic safety workbench. Drawings and materials should be placed in an anti-static document bag.
2. The anti-static wrist strap should wear an anti-static wrist strap directly in contact with electrostatic sensitive devices. The wrist strap should be in good contact with the human skin. The wrist strap must be non-irritating or allergic to the human body. The resistance value of the wrist strap system to the ground Should be in the range of 106～108Ω.
3. Anti-static container During the development and production process of electronic equipment, all storage and turnover SSD containers (component bags, transfer boxes, printed board racks, component storage boxes, etc.) should have electrostatic protection performance. Metal and ordinary plastic containers are not allowed. When necessary, the turnover box for storing components should be grounded.
4. Ion wind static eliminator should use ion wind static eliminator to eliminate static charge on the surface of insulating material.
5. Anti-static work clothes a. People who enter the anti-static work area or come into contact with the SSD should wear anti-static work clothes. The anti-static work clothes fabrics should meet the requirements of GB 12014. b. In an environment where the relative humidity is greater than 50%, pure cotton products are allowed for anti-static work clothes.
6. Anti-static work shoes. People who enter the anti-static work area or come into contact with SSD should wear anti-static work shoes. Anti-static work shoes should meet the relevant regulations of GB 4385. Under normal circumstances, ordinary shoes are allowed, but conductive shoe bundles or heel straps should be used at the same time.
7. Anti-static transport vehicles should use anti-static transport vehicles when transporting SSDs or the entire parts and components containing SSDs.
