What anti-static facilities should be provided in the production of electronic products
1. Electrostatic safety workbench
a. The electrostatic safety workbench is the basic part 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. Anti-static wrist strap: All personnel who directly touch electrostatic sensitive devices should wear an anti-static wrist strap. The wrist strap should be in good contact with the human skin. The wrist strap must be non-irritating and non-allergic to the human body. The wrist strap system has resistance to ground. The value should be in the range of 106 to 108Ω.
3. Anti-static container: In the process of electronic equipment development and production, 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: Ion wind static eliminator should be used to eliminate static charge on the surface of insulating materials.
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 fabric should meet GB12014 regulations.
b. In an environment with a relative humidity greater than 50%, pure cotton products are allowed for anti-static work clothes.
6. Anti-static work shoes: Those 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 GB4385. 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 vehicle: When transporting SSD or the whole parts and components containing SSD, transport vehicles with anti-static performance should be used.
