Generation of ESD: If there are no preventive measures, electrostatic discharge will occur uncontrollably at any time and any place. For example, when you touch the electrostatic sensitive components on the circuit board, discharge may occur. Discharge will be extremely destructive to electronic devices. For some electronic components, the harm of ESD is just like the harm of lightning to the human body.
Why is this so? Because the internal circuits of electronic components are very delicate, the energy of static electricity (although the absolute energy value is not high) is enough to damage the internal circuit structure of electronic components.
This kind of ESD damage is more serious than directly destroying electronic products (because the damaged electronic components may pass the inspection and testing of parts, and the device failure is found in the subsequent assembly process, which will lead to increased costs caused by rework or replacement of components), especially (if the product passes all work inspections and tests, and fails after the user has used it for a period of time, the cost of repair and replacement will be many times higher than the cost of discovering and solving the problem at the manufacturing stage, and the user will lose valuable confidence in the product).
