LED production technology has gradually matured in China, and its application fields have become widespread and popularized. However, most LED manufacturers are not fully equipped to produce such products, which brings hidden dangers to LED products and affects the entire market.

Causes of static electricity generated during LED production

Microscopically, according to the theory of atomic physics, when a substance is electrically neutral, the substance is in an electrical equilibrium state. Because of the gain and loss of electrons generated by the contact of electrons of different substances, the substance loses its electrical balance and generates an electrostatic phenomenon.

From a macroscopic point of view, the causes are: friction between objects, heat generation, excitation of electron transfer; contact and separation between objects to produce electron transfer; electromagnetic induction causes an imbalance in the surface charge of the object; the combined effect of friction and electromagnetic induction.

The electrostatic voltage is generated by the contact and separation of different kinds of substances. This effect is known as triboelectric charging, and the voltage generated depends on the nature of the material itself that rubs against each other. Since the LED product is mainly in the actual production process, the direct contact and indirect contact between the human body and related components generate static electricity. Therefore, according to the characteristics of the industry, we can do some targeted static precautions.
