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 of this consultation is the electronics factory that produces the electronic sensor chip of the automobile engine. The anti-static wrist strap ordered by the customer cannot pass the test of the human body comprehensive tester. On-site inspection by our engineers and technicians revealed that the problem occurred from the anti-static yarn in the inner layer of the wristband, which was not able to conduct conduction. 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 of poor quality is used for a period of time, the anti-static wrist strap wire is continuously bent, which will eventually break the metal fiber in the wire. The failure of the anti-static function of the wrist strap is caused. The wrist straps of foreign big brands have undergone strict suspension weight bending tests. 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. There are also some quality products with almost no damage caused by normal wear and tear, providing customers with lifetime quality assurance.
