Principles, functions and advantages of anti-static wrist straps
The anti-static wrist strap consists of a conductive elastic band, a movable buckle, a spring PU cord, a maintenance resistor, and a plug or alligator clip. It is a small device that releases static electricity stored in the human body to maintain the safety of electronic chips. These products are divided into wired wristbands, cordless wristbands and smart antistatic wristbands. According to the structure, it is divided into single-loop wristband and double-loop wristband.
principle:
This product is equipped with a snap button on the outside of the plastic block. The buckle passes through the metal connector and the plastic block, and is connected to the conductive strip inside the plastic block, thereby forming two independent circuit loops. The plastic block is divided into left and right parts. The two plastic blocks are connected to each other, and the buckles on the outer sides of the two plastic blocks are respectively connected to their respective grounding terminals. This product is compared with the existing traditional wristbands. Without the knowledge of the wristband wearer, even if one circuit fails, the other circuit can continue to work, reducing the possibility of electrostatic breakdown of the insulating layer of electronic components, avoiding a large number of wasted or degraded items, and operating costs low. Extend the service life of the wristband.
Features:
Use a wrist strap to ground the operator. This simple method is a cost-effective and effective way to control static electricity and can produce the most direct effect. The wrist strap can dissipate the static electricity of the human body before the static electricity damages the electronic products. Therefore, anti-static wrist straps are widely used in the electronics industry to fully maintain static-sensitive devices and printed circuit boards.
