ESD Anti-static specification for production workshops of precision electronic components
1. Static safety workbench: It is composed of workbench, anti-static table pad, wrist strap connector and grounding wire.
2. There should be more than two wrist strap connectors 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 sundries that are prone to static electricity on the electrostatic safety workbench. The drawings and documents should be placed in an anti-static document bag.
4. Anti-static wrist strap: Personnel who directly contact static-sensitive devices must wear an anti-static wrist strap. The wristband should have good contact with human skin, and the resistance value of the wristband system to ground should be 1 megohm.
5. Anti-static container: The component storage bag, turnover box, PCB loading and unloading rack, etc. in the production site should have electrostatic protection function. Metal and ordinary containers are not allowed, and all containers must be grounded.
6. Anti-static work clothes: Personnel entering the electrostatic work area and those who come into contact with SMD components must wear anti-static work clothes, especially in a dry environment with a relative humidity of less than 50%, the work clothes fabrics should meet the relevant national standards.
7. Personnel entering the work area must wear anti-static work shoes. Personnel wearing ordinary shoes should use conductive shoe harnesses, anti-static shoe covers or heel straps.
8. The conveyor belt and drive shaft used on the production line should be equipped with anti-static grounding brushes and support rods.
9. The ion wind static eliminator can be used on the surface of the conveyor belt.
10. Assembly fixtures, testing fixtures, welding tools, and various instruments used in production sites should be provided with good grounding wires.
11. An esd anti-static test bench should be installed at the entrance of the production site, and every person entering the production site should undergo an anti-static test, and can only enter the site after passing the test.
