Classification of anti-static wrist straps
The anti-static wrist strap is made of soft and elastic material mixed with conductive thread. It has good electrical conductivity, the length can be adjusted arbitrarily, and the spring grounding wire can withstand more than 30,000 environmental tests without breaking.
corded wrist strap
The corded wrist strap is the most basic anti-static equipment, and it is also a must-have item on the most commonly used production line. It is not only very convenient in erection and operation, but also the most affordable in price. Therefore, the wristband must be in contact with the skin when in use, and the grounding wire must also be grounded directly, and ensure that the grounding wire is unobstructed to exert its maximum effect.
cordless wrist strap
The working principle of the cordless wristband: According to the corona discharge effect and the tip discharge principle, when the accumulated charge exceeds a certain value, it will be discharged to 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, which is connected with the internal conductor loop
(1) It can be used as a high static power source due to improper contact with personnel, causing a large amount of static charge to be introduced instantaneously. When the ion neutralization is not completed, it can achieve ion neutralization with the air and water molecules outside the screw, so that static electricity can be effectively eliminated, so as to achieve static electricity leakage. The final purpose of discharge (static voltage balance).
(2) This screw can be used for potential zeroing function (just touch the screw to ground)
(3) It can be used as a loop detection terminal. Its features: convenient and reliable; static dissipation time: less than 0.5S
