1. Use the anti -static workbench
a. The anti -static workbench is a basic component of the anti -static work area. It consists of a workbench, anti -static table cushion, wristband connector, and large ground wire.
b. Anti -static table cushions should be not less than two wristband connections, one for operators, the other for technicians, inspectors or other personnel.
c. If necessary, the anti -static static elimination should be equipped on the anti -static workbench.
d. The anti -static workbench is not allowed to stack plastic boxes (slices), rubber, cardboard, glass, etc. that are prone to electrostatic debris, and the drawing materials should be installed in the anti -static file bag.
2. the personnel who directly contact the static sensitive device of the anti -static wristband should wear anti -static wristbands. The wristband should have good contact with human skin. The wristband must have no stimulation and allergies on the human body. It should be within the range of 10^6 ~ 10^9Ω.
3. In the process of the development and production of electronic equipment, all containers (component bags, transit boxes, printed shelves, component storage boxes, etc.) should be equipped with electrostatic protection performance. Metal and ordinary plastic containers are not allowed. If necessary, the turnover box for storing parts should be grounded.
4. ion wind electrostatic eliminator eliminates the static charge on the surface of the insulated material, the ion wind electrostatic elimination device should be used.
5. Anti -static work clothes.
6. Personnel who enter the anti -static work area or contact component should wear anti -static work clothes.
7. In environments with relative humidity greater than 50%, anti -static work clothes are allowed to choose cotton products.
8. Personnel who enter the anti -static work area or contact components should wear anti -static working shoes. Generally, ordinary shoes are allowed, but the conductive shoe beam or heel should be used at the same time.
Nine, anti -static transport vehicles transfer components, transport vehicles with anti -static performance should be adopted.
一、使用防静电工作台
1.防静电工作台是防静电工作区的基本组成部分,它由工作台、防静电桌垫、腕带接头和接大地线等组成。
2.防静电桌垫上应不少于两个腕带接头,一个供操作人员使用,另一个供技术人员,检验人员或其它人员使用。
3.必要时防静电工作台上应配备离子风静电消除器。
4.防静电工作台上不允许堆放塑料盒(片)、橡皮、纸板、玻璃等易产生静电的杂物,图纸资料等应装入防静电文件袋内。
二、防静电腕带直接接触静电敏感器件的人员均应戴防静电腕带,腕带应与人体皮肤有良好接触,腕带必须对人体无刺激、无过敏影响,腕带系统对地电阻值应在10^6~10^9Ω范围内。
三、防静电容器在电子设备研制生产过程中,一切贮存、周转元器件的容器(元器件袋、转运箱、印制板架、元器件存放盒等)应具备静电防护性能。不允许使用金属和普通塑料容器。必要时,存放部件用的周转箱应接地。
四、离子风静电消除器消除绝缘材料表面的静电荷应使用离子风静电消除器。
五、防静电工作服。
六、进入防静电工作区或接触元器件的人员应穿防静电工作服。
七、在相对湿度大于50%的环境中,防静电工作服允许选用纯棉制品。
八、防静电工作鞋进入防静电工作区或接触元器件的人员应穿防静电工作鞋,一般情况下允许穿普通鞋,但应同时使用导电鞋束或脚跟带。
九、防静电运输车转运元器件部件时,应采用有防静电性能的运输车。
