What products are the most basic must-have items 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, the user's anti-static wrist straps are not properly used, so that the anti-static wrist straps are used or the static electricity is not discharged. *The best effect, in addition to the anti-static wrist strap with monitoring alarm, or to choose a good quality anti-static wrist strap, in order to save costs, good quality anti-static wrist strap * 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 qualities. There is a difference in the electrical conductivity of the product. The conductivity is completely dependent on the quality requirements of the manufacturer. Many manufacturers have forgotten the professional ethics in order to occupy the market, causing many customers to suffer significant losses.
A good anti-static wrist strap is made of a soft, flexible material mixed with conductive filaments. The 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 can be broken in a few times and lose the function of releasing static electricity.
The wired wrist strap is the most basic and most commonly used product in the anti-static equipment. It is not only easy to set up and operate, but also affordable in terms of price. The reason is through the wristband and > The grounding wire discharges the static electricity from the human body to the earth. Therefore, the wristband must be in contact with the skin when it is used. The grounding wire should also be directly grounded, and the grounding wire should be unobstructed to play the *effect.
The working principle of the wireless wristband: According to the "corona discharge" effect and the principle of the tip discharge, when the accumulated charge exceeds a certain value, the potential difference is discharged to the space, thereby achieving the purpose of eliminating static electricity. Another screw is attached to the outside of the unit to connect with the internal conductor loop.
(1) It can be used as a person to improperly touch the high static power supply, causing a large amount of static charge to be introduced instantaneously. When the ions are not completed, the ion neutralization can be achieved with the air and water molecules outside the screw, so that the static electricity can be effectively eliminated, thereby achieving the static discharge. Put the (static voltage balance) * the ultimate purpose.
(2) This screw can be used for potential zero return function (just touch the screw to 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 electronics manufacturing, IC, semiconductor wafer, aerospace, aviation, electronic laboratory and other high-tech products manufacturing industry.
