How to prevent static electricity effectively
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 assembly workshop should be Consider the problem of maintaining a certain humidity, especially for those air-conditioned rooms that are closed, and should have certain humidity control equipment.
2. Lay an anti-static floor or carpet. At present, there are such plastic floor or carpet products with certain conductive properties, which can effectively suppress static electricity generated by walking of people.
3. Use an ion wind gun, ion head, ion bar, etc. to place static electricity within a certain range.
4. The semiconductor device should be placed in an electrostatic 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. This measure is most effective for the operator to wear an anti-static hand strap on the wrist with good grounding performance.
