When using phosphor and LED, it will distribute the phosphor around the semiconductor chip. The main purpose of this technology is to finish the wavelength conversion of phosphors. Collocation in the application of LED and fluorescent powder, the first need for phosphor gel dispensing operation which is convenient for application of LED phosphor dispensing machine to complete. Generally speaking, we will be using epoxy resin to phosphor to gel. Then we use the laser transformation of the fiber to make the phosphor become a yellow luminous body. The remaining blue light will become the white light we usually see after it is mixed with the phosphor.
Semiconductors generally possess less electrical conductivity at normal temperatures than those of conductors. They are more conductive than those of insulators. The semiconductor package is then semiconductor wafer is cut, the small wafer cut out of the use of LED phosphor dispensing machine and product framework in bonding, even small wafer bonding pads for dispensing glue dispensing function and frame pin composed of semiconductor components complete, in plastic a good package, the final test and inspection, this is the whole package process.
When dispensing bulb in use of LED phosphor dispensing machine, we use the glue is epoxy resin, it is because of the characteristics of the epoxy resin is suitable for dispensing work of this type, it can be extremely strong resistance performance, can protect the LED lighting chip is not affected by external influence, can also use a dispensing mode different and to change their performance by adding glue scattering agent to control the direction of the light scattering ability, epoxy resin itself has a superior performance, with anti wet glue solidification, high strength, the refraction of light, the projection efficiency is high.
