ESD generation and harm

ESD generation: If there is no precautionary measures, the electrostatic discharge will occur uncontrollably at any time, any place, for example when you are exposed to an electrostatic sensitive element on a circuit board, the discharge may occur and the discharge will cause the electronic device to produce a pole Large destructive, for some of the electronic components of ESD hazards as lightning damage to the human body.

Why is that so? Since the internal lines of the electronic components are very slim, the electrostatic energy (although the absolute energy value is not high) is sufficient to damage the internal circuit structure of the electronic components.

This ESD damage is more serious than the direct destruction of electronic products (because damaged electronic components may pass the inspection and testing of parts, and the subsequent assembly process only discovers the device failure, which will result in rework or replacement of components (If the product passes all the work tests and tests, and when the user fails for a period of time, the repair and replacement costs will be higher than the cost of finding and solving problems at the manufacturing stage Many times, and make users lose valuable confidence in the product).
