* Friction charging

* Stripping Charge

* Rolling Charge

* Spray Charging

* Inductive charging

Three basic static elimination measures

Changing conductivity, humidity control, static eliminator

* Changing conductivity

* Humidity control

* Static electricity eliminator

What factors must be considered when removing dust?

Blowing away garbage, removing static electricity from products, recycling garbage

* Blow away trash

* Remove static electricity from products

* Recycling garbage

De-static measures at the production site?

Use different countermeasures for mechanical, human, and grounding-ineffective insulators

* Grounding

* Anti-static spray

* Utilization of de-staticators

What are the types of de-statizers?

There are four types of de-statizers as follows: corona discharge type, radial line type, soft X-ray type, and UV type.

* Corona discharge type

* Radiation type

* Soft X-ray type

* Ultraviolet type

What is the difference between AC and DC methods?

Corona dischargers can be categorized into two main types: “AC mode” and “DC mode”.

* AC: good ionization balance, low ion production

* DC: poor ionization balance at close range, higher ion production

What is a friction charged sequence?

* Positively charged to the left of the ranking

* Negatively charged to the right of the ranking

Examples of malfunctions due to electrostatic induction?

Even if the workpiece is not electrically charged, if a charged object is close to a conductive body, the conductive body may be polarized internally by electrostatic induction and a discharge may occur.

* Generation of discharges from semiconductor devices

Difference between an electrical conductor and an insulator?

Conductors and insulators are charged differently

* Conductor can be grounded, conductive static electricity

* Charged insulator, grounding can not be resolved

What is the electrostatic induction phenomenon?

Electrostatic induction is the phenomenon of charge redistribution in a conductor under the action of an external electric field.

* Heterogeneous charges are attracted to the vicinity of a charged body

* A homogeneous charge is repelled to the other end of the charged body

What is electrostatic damage?

The electrostatic damage modes of devices are broadly categorized as: human body charged mode (HBM), machine mode (MM), and device charged mode (CDM).

* Human Body Battery Mode (HBM)

* Machine mode (MM)

* Device Charged Mode (CDM)

Is metal also electrically charged?

Metals (conductors) are generally considered to be electrically uncharged, however, as shown in the diagram below, when metals are in an insulated state, they also generate static electricity with friction and separation, just like insulators.

* When grounded, static electricity travels to the grounding wire and disappears

* When ungrounded, static electricity is charged because it has no way to travel

What is The principle of static electricity?

All matter consists of atoms. Atoms consist of a number of negatively charged electrons and a positively charged nucleus (protons and uncharged neutrons). The electrons surround the nucleus. These electrons are the original form of static electricity.

* That which gains electrons becomes negatively charged

* ♪ That which loses electrons becomes positively charged

How much static electricity can the human body feel?

According to the first chapter of Basic Electrostatics, when the electrostatic voltage reaches 2000V, people will feel it where their zhi senses are well developed, for example, the very front of their fingers; when the electrostatic voltage exceeds 3,000V, sparks will be generated, and their fingers will have the sensation of pins and needles.

* Static electricity that can be felt by the human body is generally above ±3kV

What is static electricity?

What is called static electricity is not absolutely static electricity, but relatively static positive and negative charges that are temporarily out of balance on a macroscopic scale.

* Static electricity is a charge at rest

* Kinetic electricity is generally alternating or direct current
