How to effectively prevent static electricity
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. There are some main measures for this:
1. Keep the environment at a certain humidity. Practice has proved that in the northern regions or in dry winters, there are far more cases of failure due to static electricity than in the southeast coastal areas or other seasons. Therefore, in some important places, such as computer rooms, laboratories, and electronic equipment assembly workshops Consider the issue of maintaining a certain humidity, especially for closed air-conditioned rooms, there should be certain humidity control equipment.
2. Lay anti-static floor or carpet. At present, there are such plastic floor or carpet products with certain conductivity, which can effectively inhibit static electricity generated by people's walking.
3. Use ion air guns, ion heads, ion rods and other facilities to place static electricity within a certain range.
4. Semiconductor devices should be placed in static plastic containers or anti-static plastic bags. 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 has good grounding performance and this measure is the most effective.
