The electrostatic protection work is a long-term systematic project. Any mistakes or omissions in any link will lead to the failure of the electrostatic protection work.
The main measures for electrostatic protection in the production process are electrostatic leakage, dissipation, neutralization, humidification, shielding and grounding.
The human body electrostatic protection system is mainly composed of anti-static wrist straps, ankle straps, work clothes, shoes and socks, caps, gloves or finger cots, etc., with functions such as electrostatic leakage, neutralization and shielding. [1]
The ground anti-static treatment mainly includes anti-static ceramic steel-based composite raised floor, anti-static all-steel raised floor, anti-static porcelain floor tiles, etc.

Grounding is very important to reduce static charge on conductors. The human body is a conductor and is the main source of static electricity generation. Therefore, we must reduce the electrostatic charge generated on people who come into contact with sensitive antistatic components or components. To prevent the generation of static electricity on the human body, it is better to ground it through the human body.
Several personal grounding devices:
In industry, the wrist strap is the most commonly used grounding device. A wrist strap will safely and effectively drain the static charge from your body, and a reasonable function of a wrist strap requires reasonable skin contact. A dirty or loose wrist strap may retain leaked static charge, rendering ESD control ineffective. Conductive footwear or foot grounding can be used or to supplement wrist straps.
Workstation Grounding
Conductive or static dissipative work surfaces are an essential part of an electrostatically safe workstation, especially those where hand assembly takes place, when using a wrist strap, for a clean work surface and properly grounded to a common point. Necessarily, conductive or static dissipative materials can generate static charges, but when they are properly grounded, they can effectively drain the static charge.
