What product is the basic compulsory product in anti-static equipment
Affordable anti-static wrist straps are available in a variety of materials on the market, and the quality is also uneven. In addition to the inappropriate use of anti-static wrist straps by users, the use of anti-static wrist straps still fails to discharge static electricity. The best effect. At present, in addition to the anti-static wrist strap with a monitoring alarm, it is still necessary to choose a good quality anti-static wrist strap to save costs. The longest anti-static wrist strap of good quality can be used for more than a year. Even more, but the cheap anti-static wrist straps on the market can only be used for one or two months, and some anti-static wrist straps have a shorter service life. From the product picture, it is impossible to distinguish between good and bad quality. There is a difference in the electrical conductivity of products. The electrical conductivity depends entirely on the quality requirements of the manufacturer. Many manufacturers forget their professional ethics in order to occupy the market, causing many customers to suffer heavy losses.
A good anti-static wrist strap is made of soft and elastic material mixed with conductive yarn. Its conductive performance is good, the length can be adjusted arbitrarily, the spring grounding wire can withstand more than 30,000 environmental tests without breaking, and some poor-quality anti-static wrist straps will break within a few times and lose the function of discharging static electricity.
Wired wrist straps are the most basic of anti-static equipment, and they are also a must-have product for commonly used production lines. Not only are they very convenient in erection and operation, but they are also often affordable in terms of price. The reason is that the use of wrist straps and > The grounding wire discharges the static electricity on the human body to the ground, so the wrist strap must be in contact with the skin when using it, and the grounding wire must also be directly grounded, and ensure that the grounding wire is unobstructed in order to achieve maximum effect.
The working principle of the wireless wrist strap: According to the "corona discharge" effect and the principle of **discharge, when the accumulated charge exceeds a certain value, it is discharged into the space due to the potential difference, so as to achieve the purpose of eliminating static electricity. In addition, there is a screw on the outside of the machine to connect with the internal conductor loop
(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 source. When the ion neutralization is not completed, it can achieve ion neutralization with the screw outside air and water molecules, so that static electricity can be effectively eliminated, thereby achieving electrostatic discharge. The final purpose of discharge (static voltage balance).
(2) This screw can be used for potential zeroing function (just touch the screw to the ground)
(3) It can be used as a loop detection terminal. Its characteristics: convenient and reliable; static dissipation time: less than 0.5S
Scope of application: Widely used in high-tech product manufacturing industries such as electronics factories, ICs, semiconductor chips, aerospace, aviation, and electronic laboratories.
