Talking about the classification and working principle of anti-static wrist strap

Anti-static wrist strapIt is composed of conductive elastic band, movable snap buckle, spring PU wire, protective resistor and plug or alligator clip. The types are divided into corded wrist straps, cordless wrist straps and smart anti-static wrist straps; according to the structure, they are divided into single-loop wrist straps and double-loop wrist straps; the elastic band of the anti-static wrist strap is woven with conductive yarn on the inner layer, and the outer layer is ordinary Yarn knitting; the length of the spring cord is 400cm, and the leakage resistance is 1M0. In addition, anti-static wrist straps can also be divided into corded, cordless wrist straps, (anti-static) static loops, wired wrist straps (anti-static), and wireless static wrist straps.

Detailed introduction of the anti-static wrist strap The wireless electrostatic wrist strap is developed based on the physical principle of (static voltage balance), based on the principle of&"In Electrostatic Engineering" static electricity is transferred by the push method between ions. , The electrostatic ions of the human body are pushed out of the drought body design (collection area) by the characteristics of the electrostatic pushing from the high electricity from the high potential, and the front and back surfaces of the conductive plate are respectively charged with "equal charges of opposite sex" through the principle of charge induction. Skin effect, because the area has built-in ion exchangers, it can easily provide the introduced electrostatic ions with the same amount of opposite charges to neutralize, so the effect of electrostatic discharge can be achieved. In addition, there is a screw on the outside of the machine, and the internal conductor Loop connection.

Anti-static wrist strap is the basic anti-static equipment, and it is also a commonly used protective equipment. It is a must-have item on the electronic production line. It is not only very convenient in erection and operation, but also more economical in price. Its principle is through The wrist strap and grounding wire discharge static electricity from the human body to the ground. Therefore, when using it, the anti-static wrist strap must be in contact with the skin, and the grounding wire must also be directly grounded. Ensure that the grounding wire is unobstructed in order to exert greater effect.
