The harm of static electricity cannot be ignored
The basic physical characteristics of static electricity are: attraction or repulsion, and there is a potential difference with the earth, which will generate discharge current. These characteristics will be the biggest hazard in the production of electronic products.
1. Electrostatic adsorption of dust reduces the insulation resistance of components (shortens life).
2. Electrostatic discharge destroys, so that the component is damaged and cannot work (complete destruction).
3. The heat generated by the electrostatic discharge electric field or current can damage the component (potential damage).
4. The electromagnetic field generated by electrostatic discharge has a large amplitude (up to hundreds of volts/meter) and a very wide frequency spectrum (from tens of megabytes to several gigabytes), causing interference and even damage to electronic products (electromagnetic interference).
If all the components are damaged, they must be detected and eliminated in production and quality control. The impact is small. If the components are slightly damaged, it is not easy to find under normal testing. In this case, it is often caused by multiple layers of processing. The damage is discovered when it is already in use. Not only is it not easy to check, but the loss is also difficult to predict. How much manpower and financial resources are required to find out all the problems, and if the failure is detected only during use, the loss may be huge. The harm of static electricity Don't ignore it!
