The main method of ESD protection

Ground
Grounding is very important to reduce the static charge generated on the conductor, which is the conductor and is the source of the main static electricity. Therefore, we must reduce the static charge generated by people who are exposed to sensitive anti-static components or components. It is best to prevent static electricity from being generated on the human body through the human body. Common grounding methods for conductors are: with an anti-static wrist strap and a working surface grounding.

2. Electrostatic shielding
Electrostatic sensitive components are exposed to static electricity during storage or transportation. Electrostatic shielding can weaken the influence of external static electricity on electronic components. The most common method is to use an electrostatic shielding bag as a protection.

3. Ion neutralization
Neutralization is important because grounding and isolation will not release charge from the insulator. The charge naturally generated during the process is neutralized or removed from the insulator and is called ionization. Ions are simple charged substances that are present in the air. Ions are produced by natural energy sources. They include sunlight, illumination, open flames and radiation. We can generate trillions of ions through the ionizer. The ionizer uses a high voltage to create a balanced mixed charged ion, and a fan helps the ion drift to neutralize on the object or region. Ionization neutralizes the static charge on the insulator in eight seconds, thus reducing their potential damage. By ionization, the combination is not a substitute for grounding or isolation, ionization only reduces the likelihood or risk of an electrostatic discharge accident. The most commonly used ion neutralization devices are ion fans, ion air guns, and the like.
