Overview of the Development of LED Packaging Dispensing Technology
LED lights are a type of lighting equipment that uses LEDs as luminous elements,with advantages such as energy conservation and long lifespan.Therefore,they have been widely used in the modern lighting field.In order to protect the internal structure of LED lights,improve their durability and waterproof performance,the surface of LED lights often needs to be sealed.At the same time,with the rise MINI-LED,there is a demand for high viscosity,high-frequency,trace,high consistency,and high-precision dispensing.Currently,the widely used technologies in the dispensing field include:time pressure dispensing,piston pump dispensing,screw pump dispensing,and jet dispensing.This article will introduce each of the above dispensing technologies one by one.This article first elaborates on the research background and purpose of the paper,and then introduces the application fields of LED packaging dispensing technology and the three major technological challenges that LED packaging dispensing technology will face in the future:miniaturization,automation,and intelligence. Then,it introduces the principles,advantages and disadvantages of four widely used dispensing methods:time pressure,piston pump,screw pump,and jet dispensing,finally,explains why the dispensing process has developed so rapidly and introduces the direction of future development.
