What should be noted during daily maintenance and inspection of the ESD work area?
1. Anti-static work clothes: Personnel entering the ESD work area and those handling SMD components must wear anti-static work clothes, especially in dry environments with relative humidity less than 50% (such as winter). The fabric of the work clothes should meet relevant national standards.
2. Anti-static wrist straps: Personnel directly handling ESD-sensitive devices must wear anti-static wrist straps. The wrist strap should have good contact with the skin, and the wrist strap system's resistance to ground should be 1MΩ.
3. ESD safety workbench: Consists of a workbench, anti-static mat, wrist strap connector, and grounding wire.
4. Plastic boxes, rubber, cardboard, glass, and other easily static-generating items are not allowed to be piled on the ESD safety workbench. Drawings and documents should be placed in anti-static document bags.
5. Anti-static capacitors: Component storage bags, turnover boxes, PCB loading and unloading racks, etc., in the production area should have ESD protection. Metal and ordinary containers are not allowed, and all containers must be grounded.
6. Anti-static work mats should have at least two wrist strap connectors, one for operators and one for technicians and inspectors.
7. Personnel entering the work area must wear anti-static work shoes. Personnel wearing ordinary shoes should use conductive shoe straps, anti-static shoe covers, or heel straps.
8. An anti-static testing station should be installed at the entrance to the production area. Every person entering the production area must undergo an anti-static test and pass before entering.
9. Conveyor belts and drive shafts used on the production line should be equipped with anti-static grounded brushes and support rods.
10. Assembly fixtures, testing fixtures, welding tools, and various instruments used in the production area should all have proper grounding wires.
11. Ionized wind static eliminators can be used on the surface of conveyor belts.
