Abstract

The invention relates to a manufacture method of a light-emitting diode packaging structure, which comprises the steps of: firstly, providing a loader and a light-emitting diode chip, wherein the light-emitting diode chip is configured on the loader and is positioned in a pit; secondly, filling a first packaging colloid in the pit, wherein the first packaging colloid covers the light-emitting diode chip, a fluorescent material is doped in the first packaging colloid; thirdly, carrying out first roasting to enable the first packaging colloid to be in a semi-curing state; and fourthly, filling a second packaging colloid in the pit, wherein the second packaging colloid covers the first packaging colloid.

Description

technical field [0001] The present invention relates to a semiconductor packaging structure and a manufacturing method thereof, and in particular to a light emitting diode packaging structure and a manufacturing method thereof. Background technique [0002] Light-emitting diodes have advantages such as long life, small size, high shock resistance, low heat generation, and low power consumption, so they have been widely used as indicators or light sources in households and various equipment. In recent years, light-emitting diodes have developed towards multi-color and high brightness, so their application fields have been extended to large outdoor billboards, traffic lights and related fields. In the future, light-emitting diodes may even become the main lighting source with both power saving and environmental protection functions. [0003] figure 1 It is a schematic cross-sectional view of a known surface-mount light-emitting diode packaging structure. Please refer to fi...
