What are the common reasons for the failure of anti-static wrist straps?
The anti-static wrist strap is divided into a corded wrist strap, a cordless wrist strap and a smart anti-static wrist strap. The structure is divided into a single-loop wrist strap and a double-circuit wrist strap, which is used to discharge static electricity of the human body. It consists of an elastic band, a snap button, and a spring cord. Protective resistor and plug or collet. The inner layer of the elastic band is woven with an antistatic yarn, and the outer layer is woven with ordinary yarn.
The customer is an electronics factory that produces automotive engine electronic sensor chips. The wrist straps ordered cannot be tested by the human body comprehensive tester. On-site inspection by our engineering and technical personnel found that the problem occurred in the anti-static yarn in the inner layer of the wristband, which did not function as a conductor. The only metal part of the movable button was the real function. Analysis of the reasons, first, at present, many products in the domestic anti-static market are shoddy. In addition, after the wristband with poor quality is used for a period of time, the bending of the wrist strap wire will eventually cause the metal fiber in the wire to break. The wrist strap has an antistatic function that fails. The anti-static wrist straps of foreign big brands have undergone strict suspension weight bending test. The product process, quality and process are strictly monitored to ensure that the products can meet the specified number of bends and the service life is 1-2 years.
