Example Embodiment
[0027] The LED packaging method uses a new substrate, the substrate uses an insulating base material as an insulating layer, and two copper substrates are interspersed on the lower end surface of the insulating layer, and corresponding circuits and electrodes are formed on them. The size of one copper substrate is larger than that of the other copper substrate, the positive electrode is formed on the large-sized copper substrate, and the negative electrode is formed on the small-sized copper substrate. An LED chip mounting slot is opened on the insulating layer, and the LED chip mounting slot is located at a position of the insulating layer superimposed on the large-size copper substrate. The LED chip mounting groove is arranged through the insulating layer, and the LED chip is placed on the exposed copper substrate at the bottom of the LED chip mounting groove, so that the LED chip is placed in the LED chip mounting groove. The insulating layer is also provided with two throug...
