When electrons transfer, a lack or excess of electrons can create an electric field, known as static electricity. The quantity of this static electric field depends on the materials involved in friction or separation, the extent of friction or separation, and the relative humidity of the surrounding environment.
Substances that readily transfer electrons (or charges) between atoms are called conductors. Those that cannot transfer electrons (or charges) are called insulators. Both conductors and insulators can become charged under the influence of static electricity.
The human body's movements or factors such as contact, separation, friction, or induction with other objects can generate several thousand to tens of thousands of volts of static electricity.
Static electricity causes serious harm in multiple fields. Frictional electrification and body static electricity are two major hazards in the electronics industry.
The main measures for static protection during the production process include static leakage, dissipation, neutralization, humidification, shielding, and grounding.
The human body static protection system mainly consists of anti-static wrist straps, ankle straps, work clothing, shoes and socks, hats, gloves, or finger cots, etc., with functions such as static leakage, neutralization, and shielding.
