Description of the Invention: [Technical Field] The present invention discloses a method for manufacturing an SMD two-color lead frame of a light-emitting diode, and particularly relates to a two-color lead frame for two-molded injection molding on a wire region. . [Prior Art] Due to the long life, non-pollution and low power consumption of Light-Emitting Diode (LED), it is the mainstream of the current green lighting wave, whether in functional lighting or landscape lighting. In the market of liquid crystal display backlighting and automotive lighting, the proportion of LEDs is highly developed. Even so, there are still some technical problems in the packaging of LEDs. The problem that the light source of LED lighting fixtures will produce uneven color dispersion is not conducive to the long-term development of the LED lighting industry. The SMD lead frame process technology of the conventional light-emitting diode has been disclosed in the Republic of China Invention Patent Publication No. 200849535, the main process of which is to mold a die seat on the wire area and then bend the pin. The pin of the buried end of the die pad can be electrically connected to the LED of the light-emitting diode. The pin exposed to the outer casing after being bent is electrically connected to the printed circuit board (pCB). In the downstream package of the LED, Weishang uses the SMD lead frame, which is mainly produced by this conventional process, and encapsulates the LED of the LED in the lead frame on 201203629. In order to solve the problem of uneven color dispersion of the light source, it must be The white surface of the die pad is treated black in various techniques. The process of treating the white surface of the die pad to black inevitably results in a prolonged process time and yield reduction of the package manufacturer. In addition, the heat generated by the LED during long-term use can also cause mottled and peeling of the black paint, resulting in the brightness of the light-emitting diode and the uneven scattering of the light source. In order to solve the problems of the prior art, the inventors have proposed a method for manufacturing an SMD two-color lead frame of a light-emitting diode based on years of research and development and many practical experiences, in order to improve the shortcomings of the above-mentioned prior art and to be compatible with its advantages. . SUMMARY OF THE INVENTION In view of the above problems in the prior art, an object of the present invention is to provide a method for manufacturing an SMD two-color lead frame of a light-emitting diode, which is manufactured by two-mold injection to manufacture a two-color lead frame structure to improve a conventional wire. In the process technology, the white surface of the die pad must be additionally processed into a black inconvenient after the LED is bonded on the lead frame, and the process cost of the downstream package manufacturer can be reduced at the same time. Improve product yield and extend product life. In order to achieve the above object, the present invention discloses a method for manufacturing an SMD two-color lead frame of a light-emitting diode, comprising the steps S11 to S17: first, in step S11, a metal substrate is provided; and then on the substrate of the 201203629 substrate. Step S12, punching a plurality of wire regions, and each wire region includes at least one pin; in step S13, plating the metal substrate; then, in step S14, performing a first molding injection on each wire region to form a pedestal whose material is a white plastic having high reflectivity, the pedestal has a function of fixing the pin; secondly, a second molding injection is performed on the pedestal to form an outer casing at step S15' The body 'the material is a non-transparent colored plastic, and the colored plastic is preferably black'. The outer casing completely covers the base to form a die seat; thereafter, in step S16, a two-stage die is performed, The pin is bent on the outer casing; finally, in step S17, the die is cut and cut to remove the foot to obtain an SMD two-color lead frame having a plurality of light emitting diodes. The SMD two-color lead frame can also be applied to other solid-state light-emitting elements such as an OLED (Organic Light Emitting Diode) lead frame and an EL (Electro Luminescence) lead frame. Therefore, the method for manufacturing the SMD two-color lead frame of the light-emitting diode of the present invention can avoid the need for the lead frame manufactured by the conventional process technology to be encapsulated on the lead frame after the light-emitting diode is mounted on the lead frame, and the positive grain must be further The self-color surface of the seat is treated with various techniques to make it black. It is difficult to avoid the heat generated by the LED during long-term use, which causes the black paint to become mottled and peeled off, resulting in the redundancy of the LED. And the poor performance of the light source, such as the unevenness of the light source, etc. 0.
