Plasma processing system LED to increase the application of bonding packaging technology:
LED light-emitting diodes with high light efficiency, low power consumption, health and environmental protection (no ultraviolet, infrared, no radiation in light), vision protection, long life and other characteristics, more and more popular by people, sales are getting greater and greater, known as the new light source in the 21st century. The packaging process of LED will produce pollution and oxidation. Lead to the lampshade and lampholder bonding colloid is not strong enough, and there are small gaps, air will enter through the gap, gradually resulting in oxidation of the electrode surface, resulting in the death o
CRF plasma processing systemf the lamp holder. The application of plasma treatment system cleaning technology of Shenzhen Chengfeng Intelligent Manufacturing Co., Ltd. is a new cleaning method that does not pollute the environment and is environmentally friendly and pollution-free. It can solve this problem for LED packaging manufacturers.


Light-emitting diode bonding is not strong mainly for the following two reasons. In the production process, the surface is inevitably contaminated with many pollutants (such as organic matter, oxide, epoxy resin, particles, etc.), thus affecting the bonding effect. LED lamps are mainly made of polypropylene, PE and other hard to stick plastics. This kind of plastic has the characteristics of low surface energy, poor wettability, high crystallinity, non-polar molecular chain, weak edge boundary and so on. In the process of bonding and packaging, it is easy to open the glue.
In the plasma cleaning process of LED lamp, the plasma processing system equipment properly solves these two problems. The plasma treatment system equipment acts on the material surface, and the positive and negative plasma generated can realize the chemical and physical cleaning of the LED material surface. It can remove the surface pollutants, such as organic matter, oxide, epoxy resin, particles, etc. In the process of PP/PE and other plastics, the plasma generated by the plasma treatment system equipment preprocesses the parts that need to be bonded through surface activation, surface etching, surface grafting, surface polymerization and other forms, so as to activate the non-polar materials, so as to ensure reliable bonding and long-term sealing.
