Static Electricity: The Invisible Killer of Electronic Components
Static electricity poses a significant threat to electronic components, acting as an invisible killer. This can be analyzed from the following characteristics:
Static electricity is insidious. The human body cannot directly perceive static electricity unless an electrostatic discharge occurs. However, even when an electrostatic discharge occurs, the human body may not feel an electric shock because the voltage perceived by the human body is only 2-3 kV. Therefore, static electricity is insidious, often damaging electronic components unnoticed.
Static electricity is latent. Some electronic components do not show an obvious performance decline after being damaged by static electricity, but repeated discharges can cause internal damage and create hidden dangers. Therefore, the damage caused by static electricity to components is latent.
Static electricity is random. Under what circumstances will electronic components be damaged by static electricity? It can be said that from the moment a component is generated until it fails, all processes are threatened by static electricity. The generation of static electricity is also random, and the damage is also random.
Static electricity (ESD) is complex. Failure analysis of ESD damage is time-consuming, labor-intensive, and expensive due to the delicate and minute structure of electronic products, requiring advanced technical skills and often necessitating the use of high-precision instruments such as scanning electron microscopes. Even so, some ESD damage phenomena are difficult to distinguish from damage caused by other reasons, leading to misdiagnosis of ESD failures as other types of failures. Before a full understanding of ESD damage is achieved, this is often attributed to early failures or failures of unknown origin, thus unknowingly obscuring the true cause of the failure. Therefore, analyzing ESD damage to electronic devices is complex.
Therefore, we should raise awareness of ESD prevention and adopt comprehensive anti-static measures to minimize the harm of ESD to electronic components.
