The hidden killer of integrated circuits is static electricity.

Electrostatic discharge is the process of charge accumulation, when the charge accumulates to a certain degree, a conductor close to it will produce electrostatic discharge. For a very simple example, in the dry winter, people walk around, friction is easy to accumulate static electricity, when we touch the metal handle or open the car door when there will be a feeling of electric shock, this is electrostatic discharge, the general body with 3000-5000V static electricity will have a significant feeling of discharge.

The same is true of semiconductor components, if the semiconductor device with a certain static power is placed alone or loaded into the circuit module, it will be immediately broken down. After the device is affected by electrostatic discharge, the functional damage may not occur immediately, but the reliability of the component will be affected.

The damage caused by electrostatic discharge can reach billions of dollars per year. Therefore, many large component and equipment manufacturers introduce expertise to reduce the accumulation of static electricity in the production environment.

To solve the electrostatic problem of integrated circuits, the following electrostatic protection measures can be taken:

1. Electrostatic protection at the operation site. Electrostatic sensitive devices should be operated in an antistatic working area.

2, the human body electrostatic protection. Operators should wear ESD clothes, gloves, shoes, hats, and wrist straps.

3. Electrostatic protection during storage and transportation. The storage and transportation of electrostatic sensitive devices cannot be carried out in a state of charge.
