Generation, influence and protection of static electricity
Grounding is implemented by:
1) The human body is grounded through the wrist strap.
2) The human body is grounded through anti-static shoes (or shoelaces) and anti-static floor.
3) The work surface is grounded.
4) Test instruments, tool holders, soldering irons are grounded.
5) Anti-static floor, ground mat.
6) Anti-static transfer truck, box, and frame are grounded as much as possible.
7) 接地 Anti-static chair is grounded.
Static shielding
Electrostatic sensitive components will be exposed to static electricity during storage or transportation. Electrostatic shielding can reduce the impact of external static electricity on electronic components. The more common method is to use electrostatic shielding bags and antistatic turnover boxes as protection. In addition, anti-static clothing has a certain shielding effect on human clothing.
Ion neutralization
Insulators are often prone to static electricity. Eliminating the static electricity of insulators is not effective with grounding methods. The commonly used method is ion neutralization (partially shielded), that is, using an ion fan in the working environment to provide a work of equal potential. region.
Therefore, in anti-static materials and anti-static facilities, products derived from these three methods can be divided into anti-static instruments, grounding system anti-static products, shielding anti-static packaging, transportation and storage of anti-static materials. Neutralization static elimination equipment, and other anti-static supplies.
