The principle analysis of electrostatic damage to the PCB board
When it comes to electronic products such as PCB boards, if there is no problem in the R&D technology, once a failure occurs, it is mostly related to static electricity. As we all know, static electricity is everywhere. As long as some tiny electronic components are broken down by static electricity, the entire production line will also face collapse. What effect does static electricity have on electronic components?
The basic physical properties of static electricity are as follows: attraction or repulsion, and there is a potential difference with the earth, which will generate a discharge current. The impact of these three characteristics on electronic components:
1. Electrostatic adsorption of dust reduces the insulation resistance of components, thereby shortening the life of components;
2. The heat generated by electrostatic discharge or current causes potential damage to components;
3. The electromagnetic field generated by electrostatic discharge has a large amplitude and extremely wide frequency spectrum, which can cause interference or even damage to electronic devices;
4. Electrostatic discharge destroys, so that the components are damaged and cannot work.
It can be seen that the hazard of static electricity is immeasurable, and companies should do a good job of protecting the people to prevent losses caused by static electricity
