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.
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. Suitable for high-end customers.
Function:
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.
Antistatic wrist strap
1. Comfortable
The bracelet is made of thermoplastic material, which is light, thin and soft. It can safely touch human skin and is easy to use. The "button" locking structure can be adjusted at will, suitable for wrists of various sizes. The conductive inner wear-resistant layer uses 3M's common "comfort pad" solution to ensure air circulation between the bracelet and the skin, so that the wearer feels more comfortable.
2. Connect
A bunch of metal wires and high-strength synthetic fibers in the connecting line are intertwined to increase tension. Each end of the ground wire is equipped with a tension release system planned by 3M. This system can reduce the tension on the terminals and help reduce the number of replacement ground wires. 3M's universal button design ensures that the ground wire is in close contact with the wrist strap, and the wearer can move freely, and the built-in 1 ohm resistor also limits the current flowing through the ground wire.
