Several professional static control measures
Briefly introduce common static control measures:
1. Grounding
Grounding is to directly discharge static electricity to the ground. This is the most direct and effective anti-static measure. For conductors and dissipative bodies, grounding methods are usually used, such as wearing anti-static wrist straps on the human body and grounding the work surface.
Grounding is implemented by the following methods:
1) The human body is grounded through a wrist strap.
2) The human body is grounded through anti-static shoes (or shoelaces) and anti-static floors.
3) The work surface is grounded.
4) Test instruments, tool clips, and soldering irons are grounded.
5) Anti-static floors and floor mats are grounded.
6) Anti-static transport vehicles, boxes, and racks may be grounded.
7) Anti-static chairs are grounded.
2. Electrostatic shielding
Electrostatic sensitive components will be exposed to areas with static electricity during storage or transportation. The use of electrostatic shielding methods can weaken the impact of external static electricity on electronic components. The most common method is to use electrostatic shielding bags and anti-static turnover boxes as protection. In addition, anti-static clothing has a certain shielding effect on human clothing.
3. Ion neutralization
Insulators are often prone to static electricity. The grounding method is ineffective in eliminating static electricity on insulators. The commonly used method is ion neutralization (partially shielding), that is, using ion fans in the working environment to provide a working area with equal potential.
