Users are rushing to do anti-static grounding project. What are the reasons?

In winter, customers who telephoned to do electrostatic grounding piles turned several times, and the number of customers signing contracts increased continuously. This made construction workers busy and dizzy, since the company promised to help customers do electrostatic grounding for more than ten years. This year, it is the most popular year. Most of the customers who inquire about static electricity grounding are saying that the commissioned OEM manufacturers have failed the inspection and the static protection has failed. Therefore, the static electricity grounding must be improved, along with high technology. Development, increase the competitiveness of the industry, and everyone is also enough to fight, these days require the construction deadline of the customers are very hot, after the quoted payment requirements for success must be immediately entered the construction.

The unit that entered the construction site today was also qualified as a contractor for commercial and industrial PK. It immediately rectified and hoped to receive the approval from the industry and commerce group again. Yesterday, the project deposit was received and the construction was immediately completed.

Anti-static grounding engineering system, Haiwei Dahang specializes in the anti-static grounding system engineering of the electronics factory. The grounding resistance is tailored to the customer's requirements. Different industries require different grounding resistance values.

Why do I need to be grounded against static electricity?

Electrostatic grounding: Static electricity is mainly caused by friction between different substances. During the production process of electronic powerhouses, the harm caused by static electricity is various. First of all, many equipment and instruments in this project are sensitive to electrostatic voltage, and static electricity will affect its normal operation and even make mistakes. Secondly, high voltage generated by static electricity may cause personal electric shock. In addition, when static electricity is severe, spark discharge may be caused. Severe fire accidents can cause incalculable and unnecessary losses to the company!

In order to eliminate the harm caused by static electricity, effective measures must be taken to eliminate static electricity. There are many ways to eliminate static electricity. However, the simplest, most effective and economical method is to take grounding measures. In an electronic manufacturing plant, all static electricity generation equipment should be used. Ensure reliable grounding. In order to prevent static electricity accumulating on equipment and human body from reaching dangerous potential, anti-static floors are used in the main production areas. In this type of floor protection materials, a network of copper wires is distributed. These metal networks form electrical paths with each other. It is used for static electricity conduction on the anti-static floor. As an electrical design co-ordination, the grounding terminal should be properly reserved on the building column of the space where the anti-static floor is located. After the floor is laid, the metal wire in the award-resistant anti-static floor is connected to the grounding terminal. In addition: the grounding terminal must be connected to the grounding electrode through the main ribs in the column so that static electricity flows through the grounding terminal along the main ribs in the column to the grounding electrode.

21 kinds of anti-static grounding related terms

1)

Ground potential or conductive material at any point of the earth is taken as zero.

2) Ground

Electrically connected to objects that can provide or accept large amounts of charge (such as on the ground, ships, or vehicle metal enclosures, etc.).

3) (static) grounding

The metal conductor (through the grounding electrode) is electrically connected to the ground, and the potential of the metal conductor is brought close to the ground potential.

4) Grounding

a, directly grounded or connected through a low impedance with the ground.

b. Connect to ground through a wire or other conductor that has little or almost zero resistance (impedance).

5) Soft ground

With adequate impedance grounding, the current is limited to the level of personal safety (usually 5mA). The required impedance of the soft ground depends on the voltage level that may be contacted by a person near the ground.

6) Direct grounding

A grounding method for conductively connecting a metal body with the ground.

7) Indirect grounding

A grounding method in which an object other than metal is electrostatically grounded, and all or part of its surface is in close contact with a grounded metal body.

8) Electrostatic discharge grounding device

In a common device, no device connected to the device in the ESD protection work area is grounded.

9) Ground Reference Plane

A flat conductive surface whose potential is used as a common reference potential.

10) Static Grounding Connection System

The charge on the electrified body leaks to the ground and dissipates the outside channel.

11) Earth ground

The use of conductive pads, conductive grounds, conductive shoes, or other various grounding devices keeps the human body in a conductive state with the earth.

12) Ground (electric) pole

A conductor or a combination of several conductors buried in the ground so as to make good contact with the earth.

13) Ground voltage

The potential difference between the charged body and the earth (so that the earth potential is zero).

14) (electrostatic) connection

The objects that do not have a good conductive path between them are conductively connected so that they are substantially at the same potential.

15) Lap

a. Any fixed combination of electrical conductivity between two objects. This combination can be a direct contact between the conductive surfaces of two objects, or it can be a solid electrical connection between two objects.

b. In electrical engineering, a method of connecting various metal parts together so that they exhibit low-resistance electrical contact to direct current and low-frequency alternating current.

16) Single point grounding

There is only one grounding point for each circuit or shield to ground. Ideally, a sub-system should only be connected to the same ground point. This method prevents the return current from flowing through the structure.

17) Take the wiring [Article, piece]

a. A metal braided wire or strip for sheet bonding.

b. A metal braid or strip [chip] that provides the necessary electrical conductivity between the component and the structure when they cannot be held in sufficient electrical contact by other means.

18) Leakage resistance

The equivalent resistance between the measured point and the earth connection system when the object is uncharged.

19) Leakage current

Refers to the electric charge on the charged body leaking through the various leak paths to the ground.

20) Electrostatic leakage channel

The electrostatic charge in the charged area passes through the interior and surface of the charged body and causes it to leak.

21) Stray current

Any current that does not flow in the specified path, these non-designated paths can be ground, pipelines connected to the earth, and other metal objects or structures.
