[Text|High-tech LED reporter Yue Mengdi] In the first half of 2014, the LED industry has brought short-term benefits to the entire upstream market due to the rapid growth of downstream application market demand. The chip industry is gradually out of the doldrums and the market is beginning to recover.
However, the situation in which the chip industry does not increase revenue has not changed. The first- and second-line chip makers still face great pressure, especially those that do not have core competitiveness. It has been asserted that chip companies that do not have more than 30 MOCVD companies will be eliminated in the future.
In the context of increasingly clear market competition, the frequency of technological innovation has increased, and flip-chip technology has also been developed. Because the technology reduces the gold wire packaging process, saves the lead frame, wire drawing and other processes, leaving only the chip with the phosphor and the package adhesive, can greatly save cost and labor, and is widely welcomed by the chip manufacturers.
In recent years, Yuanrong Optoelectronics has focused on the development of Blu-ray chips, and has made great achievements in the research and development of flip chip. This year, Yuanrong Optoelectronics will participate in the 2014 Golden Globe Awards with 10-33 series LED flip chip.
It is understood that the current average efficiency of flip chip in China is about 120lm/W, but the light efficiency of 10-33 series products can reach above 140lm/W, and the IR yield is over 90%, exceeding the current average yield of 80%. Moreover, the 10-33 series accelerates aging for 1000h at 300mA, and the light decay is only 5%.
"Now the flip chip has a dead light rate of 30% at high temperature, high humidity and 3 times rated current, but the flip chip of Yuanrong Optoelectronics can still work normally at 5 times rated current." Chen Xiangdong, person in charge of Yuanrong Optoelectronics Co., Ltd. Introduced,
The reporter learned that the 10-33 series uses the bonding technology between multi-layer structures, and adopts RTL (reflective transmission layer) structure and thickness design and RCBL (reflective current blocking layer) design, which is conducive to current and light output. More even.
In Chen Xiangdong's view, 2014 was the first year of Flip Chip, and the supply of products was far less than the demand. In many fields, the application of flip chip has replaced the trend of formal wear. As a raw material for making LED lamps, flip chip not only has great advantages in performance, but also greatly promotes the price drop of LED lamps as a whole.
