Why use low-temperature plasma generators in the LED lighting industry?

Before cleaning the LED, it can be treated with a low-temperature plasma generator!

Low temperature plasma processors are committed to providing solutions for customers in industries such as automotive, semiconductor manufacturing, textile technology, electronics, microelectronics, biotechnology, healthcare, plastics and rubber, scientific research and development, helping customers enhance product quality and work efficiency, and reduce adverse environmental impacts.

LED lights have the characteristics of high luminous efficiency, low energy consumption, health and environmental protection, vision protection, and long lifespan, and are increasingly favored by consumers. However, there are dirt and oxide layers in the packaging process of LED, which cause the bonding glue between the lamp and the lamp holder to be not strong and tight enough, resulting in small gaps. Air will enter through the gaps, and the electrode and bracket surfaces will gradually oxidize, causing damage to the lamp.

Low temperature plasma processors do not cause any pollution to the environment and are a new type of environmentally friendly cleaning method that can solve this problem for LED production enterprises. For example, during the production process, the surface is inevitably contaminated with a large amount of dirt, such as various organic compounds, oxides, epoxy resins, and small particles remaining on the surface of many products. 

In addition, silicone rubber products such as PP have low surface properties, poor wetting ability, high crystallization, early non-polar molecular chains, and weak edge boundaries. When bonding with glue, it is easy to have weak adhesion and opening. Low temperature plasma processors perfectly solve these problems in the plasma cleaning process of LED lamps.

When plasma cleaning equipment is used on the surface of materials, the positive and negative ionized plasma generated can chemically clean the surface of LED materials, achieving molecular level dirt removal. In addition, when the plasma generated by the plasma cleaning machine is used to treat plastic products such as PP and PE, it undergoes surface cleaning activation, surface etching, surface grafting, surface polymerization, and other forms to activate non-polar materials, thereby ensuring reliable adhesion and long-term sealing of the adhesive,

The roles of atmospheric plasma processing machines in the LED industry are as follows:

1. Atmospheric plasma processors can remove pollutants from the surface of substrates, which is beneficial for silver paste paving and chip bonding.

2. The atmospheric pressure plasma generator can enhance the adhesion of welding between leads, chips, and substrates, and improve the bonding strength on the surface.

3. Atmospheric plasma cleaning equipment can quickly clean the oxide layer or dirt, making the chip and substrate more tightly bonded.

4. The atmospheric plasma cleaning machine enhances the tightness of the colloid and bracket combination, preventing air infiltration and causing adverse effects.

In short, low-temperature plasma cleaning machines can further increase the surface performance. By introducing active groups, the adhesion between LED surfaces and other materials can be greatly enhanced. During the packaging process, the encapsulation adhesive can be tightly bonded to the surface of the LED chip, reducing the occurrence of bubbles, delamination and other problems, improving the reliability and stability of the packaging, and thus extending the service life of the LED.
