[0002] Most of the current light emitting diode (Light Emitting Diode, LED) packaging structure is to form a reflective cup on the substrate, and the reflective cup is formed by recessing from one surface of the substrate to the other surface. The depth is at least greater than the thickness of the light-emitting diode, and the thickness of the reflective cup on the substrate is usually set within a certain range to ensure sufficient strength to support the light-emitting diode in the reflective cup. Therefore, the substrate in this light-emitting diode packaging structure The thickness of the light-emitting diode packaging structure is relatively large, resulting in a large thickness of the packaged light-emitting diode packaging structure
For some thinner LED packaging structures, for example, a through hole is provided on the substrate, and an electrode layer is provided on the outside of the substrate to support the LED located in the through hole. In order to ensure sufficient support strength, it is often necessary to install There are at least two or more electrode layers, resulting in a complex package structure, and setting multi-layer electrode layers will lead to a very complicated manufacturing process and low yield
