Electronic industry esd anti-static wrist strap to choose wired or wireless
ESD wrist strap is an important part in the electronics industry to prevent the harm caused by static electricity generated by the human body, especially when the working environment itself does not fully reach the level of anti-static work area, anti-static wrist strap is the most simple, effective and easy to detect. . But there are two types of anti-static wrist straps on the market today - wired and wireless, so which one should you choose?
Let’s talk about the wireless type esd wrist strap first. The wireless type discharges static electricity through tip discharge. Usually, it can only discharge when the voltage exceeds 1500V, and it is more dependent on the air humidity. Once the humidity is reduced, the effect will become worse. The wired type directly discharges static electricity to the ground through the grounding wire, so there is no requirement for electrostatic voltage, and the wired type is connected in series with a 1 megohm resistor to divide the voltage and limit the current, which can protect personnel. Therefore, if there are no special requirements, it is best to choose a wired anti-static wrist strap.
