What harm does static electricity have on the electronics industry?
The development of electronic products is becoming more and more refined, and the production process is becoming more and more strict. If there is a difference between each process, the quality of the entire product will be affected. In the autumn and winter seasons, there is more static electricity. This is also the most protective need in the electronics industry. What harm does static electricity have on the electronics industry?
1. Process offset caused by cross-contamination or electrostatic repulsion caused by electrostatic adsorption
Electrostatic attraction, the electrostatic field generated by static charge, attracts the slight particles (fine dust in the air, light-weight foam), and the adsorbed particles become foreign matter, causing special pollution, or May cause a short circuit.
2. Temporary dysfunction caused by static electricity residue
Electrostatic residue means that the static charge resides on the surface of the object, and the electrostatic field generated by the static charge interferes with the normal working performance of the electronic device or device. At present, in the field of LCD panel manufacturing, the vacant ground is represented by an abnormality of the panel screen display (the gray screen of the LCD panel caused by static electricity is purple, and may also cause a bright spot on the LCD gray screen display).
3. Failure of electronic devices caused by electrostatic discharge
Electrostatic discharge, especially rapid release, may cause failure of the internal structure of some electronic devices according to different degrees of electrostatic discharge conditions and electrostatic sensitivity of electronic devices, resulting in abnormalities of the original functions of electronic devices, common electronic devices. ESD damage symptoms, electronic damage caused by typical ESD - breakdown.
4. Electromagnetic interference caused by electrostatic discharge
The rapid electrostatic discharge process will produce different levels of electromagnetic interference signals. Since EMI is mostly high-frequency signals, it will be received by nearby test equipment or other assembly equipment, which may cause failure or temporary malfunction of electronic devices. .
