How to effectively prevent static electricity generation
First of all, from the perspective of the mechanism of static electricity generation, we should start with reducing the insulation of related objects, so that the two objects will not generate or generate less static electricity even if they are rubbed. The following main measures are taken:
1. Keep the environment at a certain humidity. Practice has proved that in northern areas or in dry winters, there are far more cases of failures due to static electricity than in the southeast coastal areas or other seasons. Therefore, it should be considered in some important places, such as computer rooms, laboratories, and electronic equipment assembly workshops. The problem of maintaining a certain humidity, especially for those closed air-conditioned rooms, should have certain humidity control equipment.
2. Lay anti-static floor or carpet. At present, there are plastic floor or carpet products with certain conductivity, which can effectively inhibit static electricity generated by people's walking.
3. Use ion air gun, ion head, ion rod and other facilities to prevent static electricity generation within a certain range.
4. Semiconductor devices should be placed in an anti-static plastic container or anti-static plastic bag. This anti-static container has good conductivity and can effectively prevent the generation of static electricity. Of course, the conditions should be placed in a metal container or wrapped in metal foil.
5. The operator should wear an anti-static hand strap on his wrist. This kind of hand strap should have good grounding performance. This measure is the most effective.
