Electrostatic adsorption of dust reduces the insulation resistance of components and shortens the service life; Electrostatic discharge (ESD) damage, resulting in electronic components cannot work; the electromagnetic field produced by electrostatic discharge has a large amplitude and a wide frequency spectrum. Such electrostatic noise and electromagnetic interference make electronic equipment unable to work normally or even damaged.   Pay attention to:   The wristband should keep the body and the ground equipotential. ESD protection workbench should keep equipotential between device and ground. It is not allowed to place electrostatic insulating materials in the safe area .The circuit board with IC must be handled on the antistatic workbench. Wristbands and shoe covers should be tested every day to ensure that they meet the parameter requirements.   All instruments and equipment shall be grounded. Regard all components as electrostatic sensitive devices. Never touch sensitive devices or components without good grounding.   In the absence of other anti-static measures, do not take the IC installed in the anti-static tube.
