The IC itself. It carries static electricity.
The electrostatic voltage usually caused by the human body is above 2-4kv, usually caused by slight movements of the human body or friction with the insulation layer. In other words, if the electrostatic potential in our daily life comes into contact with an ic, almost all ics will be destroyed. This danger exists in any working environment, do not take electrostatic protection measures. The harm of static electricity to integrated circuits is not only reflected in the manufacturing process of electronic components, but also in the assembly and remote transmission process of integrated circuits.

Therefore, to solve the electrostatic problem of the device is mainly to solve the electrostatic problem of the plastic base (the integrated circuit formed by the micro-electronic device is placed on the plastic base).

The solution?

The antistatic agent is directly added to the substrate raw material, and after it is compatible with the product raw material, a conductive grid is formed inside the substrate to accelerate the internal electrostatic leakage and avoid electrostatic damage to the device. (Select the appropriate antistatic agent according to the process type of the plastic substrate and the properties of the substrate.)
