The purpose and general principle of electrostatic protection
The fundamental purpose of electrostatic protection is to prevent or cause damage caused by static electricity mechanics and discharge effects through various protective means during the manufacture and use of electronic components, components and equipment, or to minimize these hazards. To the extent that the design performance and performance of components, components and equipment are not impaired by static electricity.
As we mentioned earlier, the main form of electrostatic hazard in the electronics industry is the sudden failure and potential failure of components caused by electrostatic discharge, which in turn causes the performance of the whole machine to decline or fail. Therefore, the main purpose of electrostatic protection and control should be to control electrostatic discharge, that is, to prevent the occurrence of electrostatic discharge or to reduce the energy of electrostatic discharge to the damage threshold of all sensitive devices.
In principle, electrostatic protection should be carried out from two aspects: controlling the generation of static electricity and controlling the dissipation of static electricity. Controlling the generation of static electricity is mainly to control the selection of materials in the process and process. Controlling the dissipation of static electricity is mainly to quickly and safely discharge static electricity. Release and neutralization; the result of the combination of the two may make the electrostatic level not exceed the safety limit and achieve the purpose of electrostatic protection.
