Why wear an antistatic wrist strap when using electronic equipment?
Precautions taken to prevent personal clicks, fires and explosions, failure and damage of electronic components, and adverse effects on production caused by static buildup. The precautionary principle is mainly to suppress the generation of static electricity, accelerate the leakage of static electricity, perform static neutralization and the like. When a person wears a non-conductive shoe, it generates and accumulates electric charge due to activities such as walking, and can reach a potential of a kilovolt level. The highest potential generated by walking, undressing, etc. on the blanket can reach 2,450 kV. At this time, when people touch other objects, they will generate spark discharge and be clicked. Anti-static measures in human activities mainly include: wearing conductive shoes, overalls and underwear are not suitable for chemical fiber fabrics; anti-static overalls mixed with conductive fibers or treated with antistatic agents; working ground for conductive treatment; anti-static wrist Belt and so on. When two different objects are in contact with each other, a charge shift occurs at the interface, and the positive and negative charges are arranged to form an electric double layer. If the object is separated, an equal amount of charge of different polarity is generated on each of the two objects.
How should the anti-static bracelet be worn?
1. Clean your hands and keep them dry, which will reduce the generation of static electricity and the dirt on the components when touching electronic components.
2. Wear the electrostatic wrist strap on your wrist and place the metal piece inside the electrostatic wrist strap in close contact with the skin. Note that the metal sheet is to be in close contact with the skin and cannot be worn on clothing.
3. Clamp the metal clip of the anti-static wrist strap to the bare copper of the grounding wire, which can be used to discharge static electricity.
