In today's advanced electronics industry, we must grasp the key to the problem of static electricity and eliminate the symptoms of static electricity. In the electronic manufacturing industry, the major categories of static electricity are divided into the following categories:
First, the process offset caused by electrostatic adsorption induced cross-contamination or electrostatic repulsion
Electrostatic attraction, due to the electrostatic field generated by the static charge, attracts the slight particles (fine dust in the air, light foaming material) attached to the helium, and the adsorbed particles become foreign matter, causing special pollution, or May cause a short circuit.
Second, the temporary function caused by electrostatic residue abnormal
Static electricity residue refers to the electrostatic charge residing on the surface of the object, and the electrostatic field generated by its electrostatic charge interferes with the normal working performance of electronic devices or equipment. At present, in the LCD panel manufacturing field, the display of the panel screen is vacant. (The gray screen of the LCD panel may be purple due to the static electricity residue, and it may cause the LCD gray display to show bright spots).
Third, electrostatic discharge induced electronic device failure
Electrostatic discharge, especially rapid discharge, according to the different degrees of electrostatic discharge conditions and the electrostatic sensitivity of electronic devices, will cause the failure of some electronic device internal structure, resulting in the original electronic device function is abnormal, common electronic devices ESD damage symptoms, typical electronic damage caused by ESD - breakdown.
Fourth, the electromagnetic interference caused by electrostatic discharge
The rapid electrostatic discharge process will produce different levels of electromagnetic interference signals. Since EMI is mostly a high-frequency signal, it will be received by nearby test equipment or other assembly equipment, which may cause the failure of electronic devices or temporary malfunction. .
In view of the fact that static electricity may cause many of the above types of problems, the types of problems associated with static electricity must be identified in the actual response, and then efforts must be made to find effective solutions, so that problems caused by static electricity must be gradually resolved.
On the contrary, if the problem of static electricity is not effectively identified and the elimination or suppression of the static power supply is directly addressed, the Metropolis will either encounter difficulties in its feasibility or encounter a bottleneck in its effectiveness, thus ending ESD protection. .
