Electrostatic hazard:

Electronic products are extremely sensitive to static electricity in the manufacturing process. Especially in the circuit designed with lower and lower working voltage, because the gate oxide film of the device is very thin, the withstand voltage limit is very low, and a small charge can cause damage to the device. Electrostatic discharge can immediately charge the internal inter electrode capacitance of the device to a high voltage, causing the oxide to be destroyed, resulting in short circuit, open circuit, breakdown and melting of the metallized layer. The main performance is:

1. Static electricity absorbs dust and reduces the insulation resistance of components.

2. The electrostatic discharge is damaged, making the components damaged and unable to work.

3. The heat generated by electrostatic discharge electric field or current injures the components.

4. The electromagnetic field generated by electrostatic discharge has a large amplitude, up to hundreds of volts per meter, and the spectrum is extremely wide, up to several thousand megabytes, causing interference and even damage to the electronic generator.
