The lines of integrated circuit components have shrunk, their withstand voltage has decreased, and their line area has shrunk, which weakens the devices' ability to withstand electrostatic shocks. Static Electric fields (Static Electric Field) and electrostatic currents (ESDcurrent) have become the fatal killers of these high-density components. At the same time, the widespread application of a large number of high-insulation materials such as plastic products has greatly increased the chance of generating static electricity. Static electricity can be generated in daily life, such as walking, air flow, and handling. It is generally believed that only CMOS-type chips are sensitive to static electricity. In fact, circuits of highly integrated components are all very sensitive.
"A. The influence of static electricity on electronic components
Static electricity attracts dust, alters the impedance between circuits, and affects the functionality and lifespan of the product.
2. The insulation or conductor of the component is damaged due to an electric field or current, causing the component to fail to function (completely destroyed).
3. Due to the heat generated by instantaneous electric fields or currents, components may be damaged but still function, resulting in a shortened lifespan.
B. Characteristics of Electrostatic Damage:
1. Concealment: The human body cannot directly perceive static electricity unless static discharge occurs. However, even when static discharge happens, the human body may not necessarily feel an electric shock. This is because the electrostatic discharge voltage perceived by the human body is 2 to 3KV.
2. Latent nature: Some electronic components may not show a significant decline in performance after being damaged by static electricity. However, repeated cumulative discharges can cause internal damage to the components, creating hidden dangers and increasing their sensitivity to static electricity. There is no way to cure the problems that have arisen.
