Anti-static wrist strap selection skills
Anti-static wrist straps are the most basic consumables in electrostatic equipment, and the static sensitivity that is commonly used is gone.
It is easy to operate, affordable, and easy to use. Its working principle is to discharge the static electricity on the human body to the earth through the wrist strap and the grounding wire. Therefore, the wrist strap must be in contact with the skin when using it, and the grounding wire should be directly grounded, and the grounding wire should be unobstructed to achieve maximum effect. How to choose a good quality anti-static wristband?
1. The inner layer of the wrist part of a good anti-static wristband is made of silver wire, and the more the number of turns, the better the electrical conductivity;
2. The wrist strap is connected to the PU line more strongly than the PVC line, and has better resilience;
3. The internal material of the grounding wire is preferably copper wire;
4. The number of bends between the ground wire and the wrist strap can be detected by the corresponding instrument. If there is no user of the test instrument, it is recommended to obtain the corresponding third-party test report from the purchaser.
Through the above tips, I believe that you can choose the product that suits you best.
