ESD is a kind of electrostatic discharge, that is, the charge transfer caused by different potentials approaching each other. I believe that many people are often injured by static electricity in the dry season, so special attention should be paid to the issue of fixed-point protection. As a source of such hazards, we will find that the damage caused by electrostatic discharge is still very obvious, especially in the manufacturing of the electronics industry. This damage itself is not only more important to the human body, but also affects some related equipment.

What is one reason for the emergence of ESD: the human body has extensive contact and is prone to frictional charging, so it is often easy to transfer the body's charge to other things for discharge. In addition, the capacitance between the human body and the earth is still there, and the easily generated static electricity is still relatively high. Therefore, when the resistance of the human body is low, the resistance of finger contact will easily generate electricity, thus causing harm to the human body.
Is there any way to protect against ESD? Understand the generation of static electricity. This is also because when you take off clothes, you will see this blue light or your fingers will discharge when touching each other. Or dry weather and dry air will also produce static electricity. Commonly speaking, it will start when rubbing glass. In addition, this kind of induction air cushion also generates static electricity in front of the screen.
Although static electricity cannot be eliminated, it can be well controlled. For example, protection against static electricity during operation is still very important. Therefore, in this kind of static electricity disposal, we must avoid using materials that easily generate static electricity. In addition, the grounding effect must be better, such as using conductive foam or conductive cloth to face the danger of static electricity. When causing damage, we should pay attention to the method of using isolation sheets. One of the anti-static functions of the circuit board is to guide it, and the other is to block a path for this discharge. Therefore, we can see that this design appears from all aspects, which is to avoid the occurrence of static electricity as much as possible, thereby providing better protection.
