Comparison and analysis of the performance of cordless and corded anti-static wrist straps

CordlessAnti-static wrist strapIt is an anti-static device that has been gradually developed in recent years. It is designed using the principle of corona discharge. The purpose of its design is to make relevant practitioners more comfortable when working, and will not be restricted by the grounding wire, which will affect work efficiency. However, many people still have doubts about the effect of the cordless anti-static wrist strap. The following is a simple test of the cordless anti-static wrist strap and the corded wrist strap for comparative analysis.

Through the relevant test analysis of the corded and cordless wristbands, it can be found that the corded anti-static wristband has a shorter time to discharge the static electricity of the human body, while the cordless wristband needs to go through more steps, and the relative time will be a little longer. . However, because the cordless is designed after improving the functional principle of the cord, it first collects all the static electricity in the human body, sends it to the collection area and then releases it. It needs to go through the three steps of collection→transmission→release. The electrostatic discharge time is also less than 0.01 second, so it does not affect its function of collecting static electricity from the human body, but when it releases static electricity, it needs the cooperation of the surrounding environment to achieve better results, so its electrostatic discharge efficiency It is better to have a rope anti-static wrist strap, which is generally around 75%. Its electrostatic discharge must rely on the surrounding environment to discharge electrostatic ions, so its efficiency is about 75% to 80% of that of ordinary wristbands.

In short, the cordless anti-static wrist strap has the advantages of convenience and safety compared with the corded wrist strap, but at the same time, the cordless wrist strap has the disadvantages of high cost of use and low power leakage efficiency. Although it is said that creating an environment suitable for corona discharge and not affected by surrounding factors can make the cordless anti-static wrist strap improve the efficiency of its electrostatic discharge, but with the current technology, it is not possible for the time being.
