Method for packaging white LED locally sprayed with fluorescent powder and fluorescent powder local coating structure
InactiveCN101807659APrecise quantitative formationPromote wettingSolid-state devicesSemiconductor devicesFluorescenceEngineering
The invention discloses a method for packaging a white LED locally sprayed with fluorescent powder. The method comprises the following steps: after an LED chip is subjected to die bonding and wire bonding on a power bracket, putting the LED bracket into a die, and exposing the chip and an edge area; atomizing the sprayed fluorescent powder by using an atomizing nozzle of an automatic glue dispenser, and connecting fine fluorescent powder glue drops on the surface and side wall of the chip into a film; treating the surface of a heat sink of the bracket by using plasmas, and mainly converging the glue drops at the periphery of the chip; and forming a layer of uniform fluorescent powder glue film, and forming the local coating of the LED fluorescent powder after thermocuring or ultraviolet curing. The photochromic uniformity of the white LED is improved; and because the fluorescent powder forms the uniform coating layer on the surface and the side face of the chip through surface tension, the ratios of fluorescence excitation and chip emitting light in various directions are almost equal, and the photochromism is uniform.
