What is the function of an ESD wrist strap?

The ESD wrist strap is easy to use, and it takes less than a minute for the wearer to easily put the wrist strap on the hand. The anti-static wrist strap can be used under wireless conditions, when the staff is working in the clean room, accidentally touched and generated static electricity, the function of the wrist strap is to quickly release these static electricity, greatly reducing the risk of static electricity. The wrist strap also has the characteristics of high temperature resistance, which is very necessary for some special high-temperature work areas, and the anti-static wrist strap can effectively reduce the probability of static electricity.

The principle of use of the anti-static wrist strap is to establish a buffer area for the release of static electricity, so as to better achieve the effect of static electricity.

The principle and function of the anti-static bracelet are as follows:

The anti-static bracelet is a classic small bracelet device used to vent the human body, which consists of five categories: corded wristband, cordless wrist strap and intelligent anti-static wristband, single-loop wrist strap and dual-loop wristband.

Principle: Using the principle of corona discharge and tip discharge, when the accumulated charge exceeds a certain value, it is discharged to the space through the potential difference, so as to achieve the purpose of eliminating static electricity.

Function: The anti-static bracelet has the functions of convenient grounding, comfort, easy management, and safety for operators.

Anti-static bracelet classification

1. Anti-static bracelet with corded wristband.

The anti-static bracelet with corded wrist strap is a kind of intimate contact with the wrist, which is worn on the wrist of the person to dissipate the static electricity of the human body and avoid the interference of static electricity. The characteristics of this anti-static bracelet with corded wristband are: it is safe and reliable, the conductive outer belt can be adjusted arbitrarily, and it is resistant to cleaning, so people can use it with confidence.

2. Anti-static bracelet with cordless wristband.

The anti-static bracelet of this cordless wristband works on the principle of using the principle of squeezing between ions. When the staff improperly touches the electrostatic power supply, resulting in the instantaneous introduction of a large amount of electrostatic charge, the staff can effectively eliminate the static electricity through the anti-static bracelet of the cordless wrist strap, and achieve the ultimate goal of electrostatic discharge (electrostatic voltage balance).

3. Intelligent anti-static wrist strap.

The intelligent anti-static wrist strap is made of high-tech weaving, which is a two-in-one combination of wristband and electrostatic detector. As a new step in the electrostatic revolution, the intelligent anti-static wrist strap can improve production efficiency and quality assurance, and finally obtain the product compliance with environmental protection certification and electrostatic certification.

Wearing anti-static wrists, keys, and insulating gloves on the hands can be anti-static, among which the anti-static wrist can introduce the static electricity of the human body into the earth through the wire connected to the wall, and the key connects the human body and the wall, which can remove the static electricity of the human body, and the insulating gloves themselves have an anti-electric shock effect, and the insulating gloves can also be anti-static.

1. Anti-static wrist

Wearing anti-static wrists on your hands can be anti-static. The anti-static wrist is composed of a wrist strap and a grounding wire, and when the human body wears an anti-static wrist, the static electricity in the body will pass through the wrist, enter the grounding wire, and then be introduced into the earth to remove the static electricity in the human body within seconds.

2. Metal objects

Wearing metal objects on your hands can be anti-static, such as keys, pinching the handle of the key with one hand, and then touching the wall or ground with the tip of the key, you can channel the static electricity in the human body into the ground through the key, so as to achieve the effect of removing static electricity.

3. Insulating gloves

Wearing insulated gloves on your hands can prevent static electricity. The insulating gloves themselves are anti-electric shock design products, there is no conductivity, with insulating gloves, static electricity will be stored in the human body, thus disappearing, general electricians will wear insulated gloves to avoid electric shock.

1. Corona discharge.

According to the "corona discharge" effect and the principle of tip discharge, when the accumulated charge exceeds a certain value, it discharges to the space due to the potential difference, so as to achieve the purpose of eliminating static electricity.

Under the action of DC voltage, either negative or positive corona collects a space charge near the tip electrode. In negative polarity corona, when an electron causes collisional ionization, the electron is driven away from the tip electrode and forms negative ions, which collect positive ions near the surface of the electrode.

As the electric field continues to strengthen, positive ions are drawn into the electrode, at which point a pulse corona current appears, and negative ions diffuse into the interstitial space. The next ionization and charged particle motion process is repeated. This cycle leads to the emergence of corona currents in the form of many pulses.

2. Double-loop belt.

The product is equipped with a snap button on the outer side of the plastic block, and the snap is connected with the conductive webbing on the inner side of the plastic block through a metal connector and forms two independent circuit circuits, the plastic block is divided into two pieces of left and right, the two plastic blocks are hinged and connected with each other, and the snaps of the outer side of the two plastic blocks are connected with the end buckles of their respective grounding wires respectively; Reduces the probability of electrostatic breakdown of the insulation layer of electronic components.
