How to effectively prevent static electricity generation
First of all, from the mechanism of static electricity generation, it is necessary to reduce the insulation of the related objects, so that even if the two objects are rubbed, no static electricity is generated and less. The following main measures are taken:
1. Keep the environment at a certain humidity. Practice has proved that in the northern region or in the dry winter, the accidents caused by static electricity are far greater than in the southeast coastal areas or other seasons, so in some important places, such as computer room, laboratory, electronic equipment, the dressing workshop should be considered. The problem of maintaining a certain humidity, especially for those air-conditioned rooms with closed shape, should have certain humidity control equipment.
2. Lay an anti-static floor or carpet. At present, such a plastic floor or carpet product having a certain electrical conductivity can effectively suppress the generation of static electricity due to human walking.
3. Use an ion wind gun, ion head, ion bar and other facilities to prevent static electricity from occurring within a certain range.
4. The semiconductor device should be placed in an anti-static plastic container or an anti-static plastic bag. This anti-static container has good electrical conductivity and can effectively prevent static electricity. Of course, the condition should be placed in a metal container or wrapped in metal foil.
5. The operator should wear an anti-static hand strap on the wrist. This strap should have good grounding performance. This measure is most effective.
