&Nbsp& Nbsp; LCD-TFT liquid crystal screens are widely used in many electronic products, and one thing is widely welcomed. Everyone will think of solving some problems. And pay attention to some things. Now let's talk about how to pay attention to the anti-static issues of LCD-TFT LCD screens< Br/>
Electrostatic adsorption of dust reduces the insulation resistance of components and shortens their lifespan; Electrostatic discharge (ESD) damage, causing electronic components to malfunction; The electromagnetic field generated by electrostatic discharge has a large amplitude and extremely wide spectrum, and such static noise and electromagnetic interference make electronic equipment unable to work properly, or even damaged. Pay attention to:
1. Wrist straps should maintain equal potential between the human body and the ground. The ESD protection workbench should maintain the equipotential between the device and the ground. Static insulation materials cannot be placed arbitrarily in the safe area. Circuit boards with Ic must be handled on an anti-static workbench. Wrist straps and shoe covers should be tested daily to ensure they meet the parameter requirements.
2. All instruments and equipment must be grounded. Treat all components as electrostatic sensitive devices. Never come into contact with sensitive devices or components without good grounding.
3. Do not use the IC installed in the anti-static tube without other anti-static measures. Use a fixed point ion eliminator in processes that may generate static electricity. If the ICs are not on the process line or anti-static workbench, store them in a grounded and shielded container. The gas and liquid flowing through Ic should be kept at low speed.
