1. The air-conditioning system must be a purification air-conditioning system with three stages of primary, intermediate, and high-efficiency filtering. Ensure that the air sent into the room is clean air, which can dilute the polluted indoor air.
2. Ensure a certain pressure in the room to prevent the air in the clean room from being disturbed by outside air. The general industrial clean room requires a pressure difference between indoor and outdoor of 5-10Pa.
3. The building envelope must ensure good air tightness, the building surface is smooth, no dust is generated, no dust is accumulated, and no leakage.
1. Maintain a certain humidity in the environment. In some important places, such as computer rooms, laboratories, and installation and adjustment workshops for electronic equipment, consideration should be given to maintaining a certain humidity, especially for closed air-conditioned rooms, there should be certain humidity control equipment.
2. Lay antistatic floor or carpet. At present, such plastic floor or carpet products with certain conductivity can effectively suppress static electricity generated by people walking.
3. The semiconductor device should be placed in an antistatic plastic container or an antistatic plastic bag. This antistatic container has good electrical conductivity and can effectively prevent the generation of static electricity. Of course, the condition should be placed in a metal container or packed with metal foil.
4. For the operator, wear an anti-static hand strap on the wrist. This hand strap should have good grounding performance. This measure is the most effective.
