Packaging method for light emitting diode module that includes fabricating frame around substrate

摘要

A packaging method for light emitting diode module that includes fabricating frame around substrate, wherein the method comprises the steps of: fabricating a printed circuit layer with a plurality of staggered nodes on a substrate; fabricating a frame around the substrate; fabricating a protruding inclined pier around the bottom rim of the inner wall of the frame; fabricating a plurality of convex reflecting microstructure points on the surface of the printed circuit layer; positioning chips and wire bonding; spraying reflecting paint on the surface of the substrate and the inner wall of the frame except the chips; filling a silica gel diffusion layer formed by mixing the silica gel and the diffusion powder into the frame; and evenly coating a fluorescent glue layer formed by evenly mixing another silica gel and fluorescent powder on the silica gel diffusion layer.
