1. The fundamental physical properties of static electricity are:

(1) Attracting or excluding;

(2) There is a potential difference with the earth;

(3) Discharge current will occur.

These three characteristics can have three impacts on electronic components:

(1) Electrostatic adsorption of dust reduces the insulation resistance of components (shortens their lifespan).

(2) Damage caused by electrostatic discharge, rendering the components unusable (completely damaged).

(3) The heat generated by electrostatic discharge electric fields or currents can cause damage to components (potential hazard).

(4) The electromagnetic field generated by electrostatic discharge fluctuates greatly (up to several hundred volts per meter) with a wide spectrum (ranging from tens of megabytes to thousands of megabytes), causing interference and even damage to electronic products (electromagnetic interference).

(5) If all components are damaged, they can be detected and cleaned up in production and quality control, with minimal impact. If the components are slightly damaged, they are not easily detected during normal testing. In such situations, damage is often discovered only through multi-layer processing and even during use, which is not only difficult to inspect, but also difficult to predict. How much manpower and financial resources are needed to identify all problems, and if faults are only discovered during use, the losses may be huge. Therefore, it is necessary to choose conductive and anti-static engineering plastics.

Characteristics of static electricity hazards to electronic products

(1) Concealment

The human body cannot directly perceive static electricity unless there is an electrostatic discharge, but when there is an electrostatic discharge, the human body may not necessarily feel an electric shock. This is because the perceived static discharge voltage of the human body is 2-3KV, so static electricity has concealment.

(2) Potential

Some electronic components do not show a significant decrease in performance after being subjected to electrostatic operation, but repeated cumulative discharge can cause internal damage to the equipment and create hidden dangers. Therefore, the harm of static electricity to the equipment has potential.

(3) Randomness

Under what circumstances will electronic components be damaged by static electricity? It can be said that from the occurrence of a component until its damage, all processes are threatened by static electricity, and these static electricity occurrences also have randomness. Its damage also has randomness, and conductive and anti-static engineering plastics can be selected for maintenance.

(4) Complexity

The failure analysis of electrostatic discharge hazards is time-consuming, labor-intensive, and costly due to the precise, fine, and tiny structural characteristics of electronic products. It requires high technical communication requirements, such as the use of scanning electron microscopy. Nevertheless, some static hazards fail as other failures. Before fully understanding the hazards of electrostatic discharge, this is often attributed to early failures or unclear situations, thus unconsciously masking the cause. So the analysis of the harm of static electricity to electronic equipment is complex. Therefore, selecting conductive and anti-static engineering plastics can better maintain electronic products.
