The harm of static electricity to electronic components and the principle of protection
According to the different types of electronic components, the degree of electrostatic damage is different, and the lowest static voltage of 100V will also cause damage to them. In recent years, as the development of electronic components tends to be integrated, the corresponding electrostatic voltage is also constantly weakened.
The electrostatic voltage induced by the human body is usually above 2-4KV, which is usually caused by the slight movement of the human body or the friction with the insulator. In other words, if the electrostatic potential in our daily life comes into contact with ICs, almost all ICs will be destroyed. This danger exists in any work environment where electrostatic protection measures are not taken. The damage of static electricity to IC is not only reflected in the manufacturing process of electronic components, but also in the process of IC assembly and long-distance transmission.
To solve the above problems, you can take the following various electrostatic protection measures:
1. Electrostatic protection at the operation site. Devices that are sensitive to static electricity should be operated in an anti-static work area;
2, human body electrostatic protection. Operators wear anti-static overalls, gloves, working shoes, working 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 charged state.
