The harm of human body static electricity
The human body causes obstacles to the work of electrostatic sensitive electronic products
The human body's electrostatic barrier is manifested in two aspects. On the one hand, because the discharge time of human electrostatic energy is very short, only a few tenths of a microsecond, the instantaneous pulse is high, and the average power is more than kilowatts, which can burn sensitive components and cause the entire electronic equipment or system to work errors and malfunctions. . On the other hand, since the electrostatic potential of the human body can be as high as hundreds, thousands or even tens of thousands of volts, it is enough to cause electrical breakdown of sensitive electronic components, including hard breakdown (causing sudden permanent failure) and soft breakdown (general performance) Is temporarily invalid). Temporary failure will not only cause errors and errors in the operation of the equipment, but the more serious harm is that it can cause potential failures without any rules to follow, and reduce the reliability of electronic products.
The so-called static protection is to eliminate static electricity or control the static voltage within the allowable range. This is a very complicated issue. There are many factors to consider when determining an air ionization system. For example, airflow, power supply, material of discharge electrode, installation, reliability and maintenance, test and effect evaluation, technical service and cost.
