Description of the Invention: [Technical Field] The present invention relates to a structural technique of a surface-adhesive electronic component, and more particularly to a thin-type light-emitting diode based on a unique metal stent structure and a wire frame structure thereof. [Prior Art] In order to control the thin-type light-emitting diode (SMD LED), the aperture angle of the light-emitting diode is generally set on the thin-type light-emitting diode (also called: photomask, light transmission). Cover...etc.) so that the thin-type light-emitting diode can emit the effect of concentrating or wide-angle illumination, or the package can be directly formed into a lens-like shape during the packaging stage of the manufacture of the thin-type light-emitting diode. Eliminate the lens settings. However, in controlling the illumination angle of the thin light-emitting diode, in addition to controlling the curvature exhibited by the lens or the package, the most important thing is to control the position of the light source to enable the generated light source to be coupled with the lens or package. The curvature of the body can make the light source conform to the pre-results' and the wafer rack height and the impact affect the focal length of the light source. Generally speaking, when (9) is set to _ high, the wafer will not be uniformly distributed. Scattering, therefore, can produce a more concentrated source (small illumination angle, effective illumination distance). In order to enable the wafer to be elevated to exhibit the desired illumination angle, a structural composite-metal stent structure is designed, and many processes must be added during the standard manufacturing process to enable the wafer to be mounted at a higher position, for example: In the internal patent publication, No. 45, "Surface Mountable Luminous 5 200952214 'Diode Package" is shown as a special component, to create a two-piece structure for the wafer holder. A cavity is reserved first, and a higher heat sink is further inserted into the cavity to enable the wafer to be mounted at a higher position. Similar techniques are required because of the increase in the manufacturing process. The process of preserving the cavity, prefabricating heat sink, placing the heat sink, fixing the heat sink, etc., not only reduces the yield of the product, but also increases the manufacturing cost. In addition, the 'National Patent Gazette's certificate number 黯9〇26 “Surface-adhesive hair-emitting diode base” shows the use of multi-layered junction stacking to create a structure for wafer holders. The method of multi-layered junction stacking may be complicated by a large number of metal substrates', and it is also necessary to increase the external work of the combined counter-alignment material, which also causes a problem of lowering the yield of the product and increasing the manufacturing cost. In view of the fact that the 'creator' is based on a metal bracket structure that allows the wafer to be placed at the optimum height position, so that it has a structure that does not need to be assembled and assembled, and is applied to the light-emitting diode and its wire frame. Therefore, the main purpose of the present invention is to provide a thin light-emitting diode wafer erection technology for the above purpose, and the present invention provides a thin light-emitting diode. The manufacturing method is to produce a unique metal stent structure in the process, and the thin metal light-emitting diode and its wire frame structure are used as the basis of the metal stent structure. The method for manufacturing a thin-type light-emitting body includes the following steps: 200952214 (A) metal ruthenium sheet formation: ray-sheet-shaped metal enamel belt) and the bottom surface of the metal ruthenium is formed as a lower bump which is arranged in parallel. (9) Stamped metal bracket: a plurality of neatly arranged metal brackets are punched on the metal slab by means of punching, '7 each metal bracket has a wafer carrying portion, and a plurality of conductive terminals spaced apart from the circumference of the wafer receiving portion. The crystal# bearing portion is located on the bump, has a thickness larger than the conductive terminal, and has a punched groove at the bottom thereof, and the top portion has an upper convex portion that is pushed upward to form the wafer when the cavity is formed; The height of the top end of the wafer carrier can be directly increased and controlled by the means of forming the eight-slot of the cymbal. (c) Wire frame forming. In the injection molding method, a bowl-shaped base is provided in each of the metal red, and a bowl-shaped receiving space is formed on the top surface of the aa sheet bearing portion and the conductive terminal, and the wafer bears the bottom surface and The cavity is exposed on the bottom surface of the bowl base, and a stepped shape is formed at the end of the wire terminal in a punching manner, so that the bottom surface of the terminal end of the terminal is located on the same reference surface as the bottom surface of the wafer carrier. -
