What is the esd electrostatic protection standard?
The esd electrostatic protection standard is GB21148-2020. It will come into effect on August 1, 2021. The anti-static national standard GB21148-2020 requires the anti-static resistance value to be greater than 100kΩ and less than or equal to 1000MΩ, that is, 100kΩ esd electrostatic principle Static electricity is usually generated artificially, such as production, assembly, testing, storage, handling, etc., it is possible to accumulate static electricity in the human body, instruments or equipment, and even the components themselves will accumulate static electricity. In this case, contacting these charged objects will form a discharge path, which will instantly damage electronic components or systems by electrostatic discharge. damage the chip. Just as the electric charge stored in the cloud layer instantly breaks through the cloud layer to produce violent lightning, which will split the earth, and usually when the rainy day comes, because the air humidity is high, it is easy to form electrical conduction.
