When the electronic product is finished, it must pass the static test and meet the antistatic discharge requirements before the product can be put on the market. Electrostatic Discharge (ESD), the generation of ESD depends on the initial voltage, resistance, inductance and parasitic capacitance of the object. The examples of possible arcing are human body, charged components and machines. Examples of possible spikes may be observed or Metal objects 'multiple arc instances that may produce the same polarity or polarity change are furniture, and most electronic products are in the above ESD environment. ' ESD interference can cause electronic products to lock up, restart, data loss, and reliability degradation.
