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 improper use of anti-static wrist straps by users makes it impossible to use anti-static wrist straps to discharge static electricity The best effect is that in addition to matching the anti-static wrist strap with a monitoring alarm, you still need to choose a good quality anti-static wrist strap to save costs. A good-quality anti-static wrist strap * can be used for more than one year. Even more, but the cheap anti-static wrist straps on the market can only be used for 1 or 2 months, and some anti-static wrist straps have a shorter service life. From the product pictures, it is impossible to distinguish between good and bad quality. There is a difference in the electrical conductivity of the product. The quality of the electrical conductivity depends entirely on the quality requirements of the manufacturer. Many manufacturers have forgotten professional ethics in order to occupy the market, causing many customers to suffer significant losses.
A good anti-static wrist strap is made of soft and elastic materials with conductive wires. Its conductivity is good, the length can be adjusted arbitrarily, the spring ground wire can withstand more than 30,000 environmental tests without breaking, and some poor quality anti-static wrist straps will break in a few times and lose the function of releasing static electricity.
Wired wrist straps are the basic in anti-static equipment, and they are also a must-have on the production line for general use. Not only are they convenient to set up and operate, they are also often affordable in price. > The ground wire discharges the static electricity from the human body to the ground. Therefore, the wrist strap must be in direct contact with the skin during use. The ground wire must also be directly grounded, and the ground wire must be unobstructed in order to exert the greatest effect.
Wireless wristband working principle: According to the "corona discharge" effect and the tip discharge principle, when the accumulated charge exceeds a certain value, it is discharged to space due to the potential difference, thereby achieving the purpose of eliminating static electricity. In addition, there is a screw on the outside of the machine, which is connected with the internal conductor circuit.
(1) As a result of improper contact with high static power sources, a large amount of static charge can be introduced instantly. When ion neutralization is not completed, ion neutralization can be achieved with external air and water molecules of the screw to effectively eliminate static electricity and achieve electrostatic discharge. The ultimate goal of discharge (static voltage balance).
(2) This screw can be used for potential reset function (just touch the screw to ground)
(3) Can be used as a loop detection terminal. Features: 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 wafers, aerospace, aviation, and electronics laboratories
