[Text / high-tech LED Xu Chaopeng] At present, eutectic ceramic packaging technology is gradually heating up in the industry. At the same time, as flip-chip LEDs are gradually gaining attention from the lighting market, more and more LED manufacturers are beginning to invest in research and development in this field. Production, in an effort to accelerate the development of flip-chip technology in lighting applications in terms of technology and cost.
This eutectic ceramic packaging technology, due to technical difficulties and complicated processes, there are only a few companies in China that have mastered eutectic technology. Among them, Jiangxi Jingrui Photoelectric Co., Ltd. (hereinafter referred to as “Jingrui Optoelectronics†") is the "front" in the middle.
For example, the latest "Car Lighting Special Lamp Bead GD2" from Jingrui Optoelectronics Co., Ltd. is a low-thermal resistance 1.60×1.60mm small-sized ceramic substrate package, combined with the molding method of the lens-fitted lens package. Package.
"The GD2 product uses Crystal Energy to independently develop a new generation of 32 mil silicon vertical structure chip. The N-type metal of the chip is converted into a Via via design by a conventional electrode wire (grid), and the N-type metal is directly connected to the substrate of the chip." Xie Chunhong, the marketing department of Jingrui Optoelectronics, told Gaogong LED.
According to Xie Chunhong, the technological innovation of GD2 products lies in the new generation of silicon vertical chip adopting Via through hole design. The through hole allows the N-type metal to be embedded inside the LED chip, and the quantum well light-emitting area (MQW) emits light to the outside of the chip without being affected by the N-electrode. Blocking, in order to eliminate the current congestion of the traditional vertical structure chip, the light effect can be significantly improved.
"Because of the phosphor film technology, this GD2 lamp bead chip has a very high color area hit rate, and the spot consistency is good. Moreover, the package form turns the flat glue into a precise optical lens, and the brightness of the lamp bead is original. On the basis of the increase of 20%." Xie Chunhong mentioned.
“In summary, compared with the mainstream technology products in the market, GD2 products are superimposed with the advantages of ceramic eutectic technology due to the adoption of a new generation of silicon vertical structure chips. They have excellent current spreading, good heat dissipation and high current resistance. 180lm, with industry-leading spot consistency." Xie Chunhong finally mentioned.
This time, Jingrui Optoelectronics' new 'Auto Lighting Special Lamp Beads GD2' will also participate in the 2015 High-tech LED Golden Globe Awards. Can you win the championship in one fell swoop, and please treat your colleagues in the circle!
