How to effectively prevent the generation of static electricity?
First of all, from the point of view of the mechanism of static electricity generation, we should start with reducing the insulation of the related objects so that the two objects will not generate and generate static electricity even if they rub. There are some main measures for the following:
1. Keep the environment with a certain humidity. Practice has proved that in the northern regions or in the dry winter, the occurrence of faults due to static electricity is much larger than in the southeastern coastal areas or other seasons, so in some important places, such as computer equipment rooms, laboratories, and electronic equipment installation and adjustment workshops, it should be considered The problem of maintaining a certain humidity, especially for closed air-conditioned rooms, should have certain humidity control equipment.
2. Lay anti-static floor or carpet. At present, there are such plastic floor or carpet products with certain conductive properties, which can effectively suppress the static electricity generated by people walking.
3. Use ion wind gun, ion head, ion rod and other facilities to prevent the generation of static electricity within a certain range.
4. The semiconductor device 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, it should be placed in a metal container or wrapped with metal foil if possible.
5. Operators should wear anti-static hand straps on their wrists. Such hand straps should have good grounding performance. This measure is most effective.
