The electrostatic principle of anti-static bracelet
The anti-static wrist strap is composed of conductive wires and metal sheets, which can continuously level or ground static electricity between users and electrical equipment. Decorate your wrist with an anti-static wrist strap, you can freely work on the machine you dream of and carry parts safely, knowing that accidental static electricity will not spoil the fun.
Use an anti-static wrist strap to ground the operator. This simple method is the cheapest way to control static electricity, and it can produce the most direct effect. The bracelet can dissipate the static electricity carried by the human body before the static electricity destroys the electronic products. Therefore, anti-static wristbands are widely used in the electronics industry to fully protect electrostatic sensitive devices and printed circuit boards.
Features of electrostatic bracelet
1. Comfortable
The bracelet is made of thermoplastic material, which is light, thin and soft. It is safe to contact with human skin and easy to use. The "pull button" type locking structure can be adjusted at will, suitable for wrists of various sizes. The conductive inner layer adopts 3M's unique "comfort pad" design to ensure air circulation between the bracelet and the skin, making the wearer more comfortable.
2. Style
There are different colors, such as blue, green, purple, maroon and fluorescent green. The supervisor can easily see whether the bracelet is used properly, and can match the company's tone to improve the company's image and coordination. Within the company, workers can also be identified by the color of the bracelet.
3. Relationship
A bunch of metal wires in the grounding wire are interwoven with high-strength synthetic fibers to increase tension. Each end of the grounding wire has a tension relief system designed by 3M. This system can reduce the tension on the end points and help reduce the number of replacement ground wires. 3M's unique button design ensures that the ground wire is in close contact with the wrist strap, allowing the wearer to move freely. The built-in one megohm resistor also limits the current flowing through the ground wire.
Static electricity
It is worth understanding the working principle of static electricity to understand how to use an anti-static wrist strap. All people have what we call potential or a certain amount of electrons.
When a person comes into contact with a computer with a different electric potential, a surge of electrons flows from the electron with a higher electric potential or a higher number of ping electrons to the computer with the lowest electric potential.
How to use an anti-static wrist strap results; that very familiar knocking feeling, we have all experienced touching metal door handles, radiators or even another person. Although harmless to us, the charging function is powerful enough to damage and destroy small and complex circuits such as motherboards, GPUs and electronic boards.
Therefore, the purpose of the anti-static belt is to balance the potential between two objects so as not to damage the equipment.
Although it is not necessary to have an anti-static wrist strap, it is strongly recommended to wear an anti-static wrist strap if you just make a mistake in warning. If we consider the cost and damage of components that may be caused by imperceptible electrostatic discharge, then just a few dollars can give you peace of mind.
