A detailed introduction to the anti-static wrist strap.

How long does an ESD wrist strap last?

Anti-static wrist strap is used to dissipate static electricity from the human body. It consists of an anti-static elastic band, a movable snap buckle, a spring cord protection resistor, and a plug or chuck. The inner layer of the elastic band is woven with anti-static yarn, and the outer layer is woven with ordinary yarn.

Main index: The maximum length of the spring cord is 250cm, and the leakage resistance is 106 (the protection resistance is 106). Corded, cordless anti-static wrist strap, electrostatic ring Wired wrist strap (anti-static) wireless electrostatic wrist strap, anti-static wrist strap Wireless electrostatic wrist strap is based on the physical principle of (electrostatic voltage balance), according to the "electrostatic engineering" static electricity is the use of the principle of inter-ion pushing, through the characteristics of electrostatic self-high electricity and high potential pushing, the human body's electrostatic ions are pushed into the drought body design (collection area), through the [charge induction principle] The positive and negative surfaces of the conductive plate will be respectively "equal anisotropic charge" - skin effect, because the built-in ion exchanger "using its low free energy characteristics" can easily provide the introduced electrostatic ions with the same amount of anisotropic charge to neutralize, so the effect of electrostatic discharge can be achieved, and a screw is provided on the outside of the machine to connect with the internal conductor circuit.

1) It can be used as an instantaneous introduction of a large amount of electrostatic charge due to improper contact with the high static power supply by personnel, and when the ion neutralization is not completed, it can provide ion neutralization (for the corona discharge effect) by the air and water molecules outside the screw, so that the static electricity can be effectively discharged, and the ultimate goal of electrostatic discharge (electrostatic voltage balance) can be achieved.

2) This screw can be used for potential reset function (just touch the screw to ground), 3) It can be used as a loop detection terminal.

Wired grounding wrist strap is the most basic anti-static equipment, but also the most commonly used production line of necessities, not only in the erection and operation is very convenient, in the most often affordable, the reason is through the wristband and grounding wire, the human body of the static electricity discharged, so the use of the wristband must be in contact with the **, the grounding wire also needs to be directly grounded, and ensure that the grounding wire is unobstructed in order to play the maximum effect.

Anti-static wrist with electrostatic ring is a device worn on the human wrist to discharge the accumulated electrostatic charge in the human body. It is divided into wired type and wireless type, with metal rings and elastic conductive wire hybrid rings. This product belongs to the anti-static wrist strap snap adjustment wired type, which can effectively protect the zero resistance parts from the interference of static electricity, and is used to dissipate static electricity from the human body.

It consists of an anti-static elastic band, a movable snap fastener, a spring cord, a protective resistor and a chuck. The inner layer of the elastic band is woven with anti-static yarn, and the outer layer is woven with ordinary yarn. The principle of the anti-static wired wrist strap is to conduct the static electricity of the human body to the earth through the wristband and grounding wire.

When using the wristband, make sure the ground wire is directly grounded for maximum effectiveness. Wearing this anti-static wrist strap, it can safely remove the static electricity generated in the human body in seconds, the grounding wrist strap is the most basic and most commonly used anti-static equipment.

It's hard to say, it depends on how you use it.

A certain electrostatic charge will be generated during product turnover and processing, and the wrist strap plays the role of discharging static charge, because the wrist strap is connected to the electrostatic grounding network, which is directly connected to the earth.

It's not very expensive, it's about five dollars, it can play a role, I hope it can help you.

Some are expensive, some are not, depending on which one you buy. It should be anti-static during the dry season.

It's not expensive, between, the corded steward, the cordless is useless.

The principle of the wristband is to conduct the static electricity of the human body to the earth through the wristband and grounding wire. The difference between the cheap and expensive anti-static wristbands is too big, and there is a big difference between them, such as the service life, the more expensive ones generally have a life span of 2 years and can be bent 60,000 times. The resistance value is about 10 to the 6th to the 9th power of 10.

The cordless wristband is the use of the principle of corona discharge, after the conductor itself is charged, it usually needs a voltage of more than 1500V, and its tip part will discharge the air to dissipate static electricity, but the static voltage required by the cordless wristband is too high to dissipate static electricity, which is not suitable for the electronics industry.

It is especially important for some highly sensitive electronic devices, and the effect is remarkable. The key is grounding, which has little to do with dry weather.

How to use: Wear the wristband on the wrist like a watch, the metal part of the wristband should be close to **, and then clip the crocodile clip to the grounding wire.

The wireless wrist strap is developed by using electrostatic voltage balance, according to the principle of "electrostatic engineering" electrostatic use of inter-ion extrusion transmission, through the characteristics of electrostatic electricity from high potential pushing, the human body electrostatic ions are pushed to the collection area, and the positive and negative surfaces of the conductive plate will be neutralized by the principle of charge induction. Therefore, the effect of electrostatic catharsis can be achieved, and a screw is provided on the outside of the wristband, which is connected with the internal conductor circuit, which can be used as a high electrostatic power source due to improper contact of personnel, resulting in the instantaneous introduction of a large number of electrostatic charges. In addition, this screw can be used for potential zero function (just touch the screw to ground), and can also be used as a loop detection terminal.

1. Wear the wristband on the wrist like a watch, but the metal part of the wristband should be close to **.

2. Clamp the crocodile clip on the personnel grounding line.

The above 2 steps are how to use the wristband, thank you.

A common method for electrostatic treatment, the principle of electrostatic wristband.

It is done by using a conductive soft belt with ground and a palm sleeve to quickly release the static electricity on your body and the tools you use into the earth.

When the human body comes into contact with integrated circuits, the electrostatic voltage on the human body will be discharged through the circuit, which will break down the electronic components and cause the circuit to fail. In order to overcome the loss caused by static electricity, the operator must wear an anti-static wrist strap, the wristband is made of conductive materials, one end of it is connected with a wire, and the other end of the wire is grounded, so that the static electricity generated by the human body is discharged to the ground through the anti-static wrist strap and plays a role in protecting electronic components from damage. Hope it helps.

Connect to the earth and release the voltage.

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.
