What is the difference between a wireless static wrist strap and a cable?
Wireless wrist straps have little meaning for electrostatic protection
The difference between these two products is the electrostatic discharge.
The wireless anti-static wrist strap is designed to dissipate static electricity when the voltage exceeds 1500V, and its tip portion discharges air, but the static voltage required for dissipating static electricity in the cordless wristband is too high, which is not suitable for the electronics industry because How many electronic components can withstand high voltages above 1500V?
The reason for the wired anti-static wrist strap is that the static electricity on the human body is discharged to the earth through the wrist strap and the grounding wire. Therefore, the wrist strap must be in contact with the skin during use, and the grounding wire must be directly grounded, and the grounding wire must be unobstructed to play. Maximum efficiency. (Note: An electrostatic grounding system must be used to maximize the release of static electricity in a timely manner)
In summary, wireless wrist straps have little meaning for electrostatic protection. We should choose a wired anti-static wrist strap with an electrostatic grounding system to calculate the specification.
