How to achieve good anti-static effect
Ground
Grounding is the connection of some anti-static products or other equipment to a ground wire. A buried line method is used to establish an "independent" ground line. The resistance between the ground wire and the earth is <10Ω, which acts to discharge the charge that may accumulate on the conductor. The static electricity accumulated on the conductor (such as the human body) is usually grounded by grounding.
Grounding is implemented by the following methods:
1 The human body is grounded through the wrist strap.
2 The human body is grounded through anti-static shoes (or shoelaces) and an anti-static floor.
3 The work surface is grounded.
4 Test instrument, tool holder, soldering iron grounding.
5 Anti-static floor, grounding pad.
6 Anti-static transfer vehicles, boxes and racks should be grounded as much as possible.
7 Anti-static chair is grounded.
2. Using a static eliminator
For example, the ion fan and ion wind gun produced by our company are very good static eliminators. The principle is that a large amount of positive and negative ions are generated on the static eliminator, and then these ions are blown to the static place by the wind, and the static electricity will be By neutralizing the ions of opposite polarity and neutralizing them, the static electricity accumulated on the surface of the product or equipment is thus neutralized and eliminated.
3. Use static eliminator
The static elimination agent can be used to wash the surface of the instrument and the object, and the static electricity on the surface of the object can be quickly eliminated. The antistatic agent uses fats and oils as raw materials, and its main component is quaternary ammonium salt. Its function is to make the surface of chemical fiber, rubber, plastic and other objects adsorb moisture in the air and increase the electrical conductivity.
4. Electrostatic shielding
* The usual method is to use electrostatic shielding bags and anti-static turnover boxes as protection. The electrostatic sensitive components will be exposed to static electricity during storage or transportation. The electrostatic shielding method can weaken the influence of external static electricity on electronic components.
