How to choose an ESD anti-static wrist strap
An esd anti-static wrist strap is a device worn on the hand to prevent static electricity from causing harm to the human body or equipment. It can be seen both in daily life and in manufacturing factories, with different shapes and various products. At this time, someone may ask, if I also buy one, how should I choose? Also, are all anti-static wrist straps useful?
Generally speaking, anti-static wrist straps are divided into two categories: wired and wireless. The wired wristband can be discharged directly after being grounded, has no voltage requirements, and can remove static electricity quickly. However, this kind of wrist strap is very inconvenient and is generally not used in daily life. It is usually used for electrostatic protection in factories, especially when making high-precision electrical components. Wireless anti-static wrist straps are very convenient to use and are generally used in daily life. The various anti-static wrist straps we usually see are basically wireless, and there are many styles of loop power-consuming wrist straps. Diverse.
To sum up, if you need to frequently come into contact with high-precision electrical components, you must choose a wired anti-static wrist strap. For ordinary people, choosing a wireless one is enough. Specifically, you can grasp the following two principles: First, do not choose The principle is lofty. The principle of static electricity is simple and easy to understand, and anti-static is not difficult from a scientific point of view. Those fancy publicity is just to sell it more expensively. Don’t be fooled, just choose something common and practical. The second is to give priority to wireless anti-static wrist straps that consume circuit power. After all, the principle of tip discharge is a natural phenomenon. The process is slower than forming a loop and actively consuming electricity. Instead of waiting for the charge to be released naturally, it is better to consume it artificially, which can more efficiently reduce the charge on the human body. quantity, thereby reducing discharge phenomena.
