1. The fundamental physical properties of static electricity are:

Attract or Repel

(2) Possesses a potential difference with the Earth.

(3) It generates a discharge current.

These three features and their three impacts on electronic components:

(1) Electrostatic attraction to dust, reducing component insulation resistance (shortening lifespan).

(2) Electrostatic discharge damage has rendered the components inoperable (complete destruction).

Section 3: Thermal damage to components due to electrostatic discharge fields or currents (potential damage).

(4) Static discharge generates electromagnetic fields with a large amplitude (up to hundreds of volts per meter) and a very broad spectrum (ranging from tens of megahertz to thousands of megahertz), which can cause interference and even damage to electronic products (electromagnetic interference).

(5) If all components are completely damaged, they can be detected and excluded during production and quality control, with minimal impact. However, if components are slightly damaged, they may not be easily discovered during normal testing. In such cases, damage is often only discovered after multiple processing stages, even when in use. Not only is it difficult to inspect, but the loss is also hard to predict. It requires a significant amount of manpower and financial resources to identify all issues. Moreover, if a failure is detected only during use, the potential loss could be substantial. Therefore, it is crucial to choose conductive anti-static engineering plastics.

Characteristics of Static Electricity on Electronic Products

(1) Confidentiality

Static electricity cannot be directly perceived by the human body unless a static discharge occurs. However, even with a static discharge, the human body may not always feel a shock. This is because the voltage at which the human body perceives a static discharge is 2-3KV, making static electricity somewhat concealed.

(2) Potentiality

Some electronic components may not experience a significant decrease in performance after being subjected to static electricity, but repeated discharge can cause internal damage to the devices, creating latent hazards. Therefore, the damage caused by static electricity to components is potentially harmful.

(3) Randomness

When can electronic components suffer from electrostatic damage? It can be said that from the moment a component is produced to the moment it is damaged, the entire process is threatened by electrostatics, and the generation of these electrostatics is also random. The damage is also random, and conductive anti-static engineering plastics can be chosen to protect them.

Complexity

The failure analysis of electrostatic discharge damage is time-consuming, labor-intensive, and costly due to the fine, delicate, and minute structural characteristics of electronic products, requiring high technical expertise and the use of high-precision instruments such as scanning electron microscopes. Despite this, some electrostatic discharge damages are misidentified as other types of failures. Before the full understanding of electrostatic discharge damage, they are often attributed to early failures or failures of unknown causes, thereby inadvertently concealing the true reasons. Therefore, the analysis of electrostatic damage to electronic devices is complex. Hence, choosing conductive antistatic engineering plastics can better protect electronic products.
