[Text / high-tech LED Xu Chaopeng] At the moment, CSP technology is carrying the eager expectations of the LED industry for small package requirements and cost-effective. At the same time, with the gradual breakthrough of technical difficulties and the continuous decline of cost, CSP has become the technical focus of the major LED brand companies competing for chase. Xiaomi, the president of Xiaomi, said, “As long as you stand in the wind, pigs can fly.†The magical gadget of CSP has been on the air of public opinion since its birth, and has guided the current LED lighting industry to undergo a major change. Market beginning "At present, Apple and Samsung's mobile phone flashes use CSP unpackaged chips. At the same time, Samsung and LG's ultra-thin TVs also use CSP unpackaged chips in part. In the lighting industry, CSP is small in size, flexible, and applicable. It will be more and more extensive," said Xiao Guowei, chairman of Jingke Electronics. According to the reporter's understanding, the first domestically applied flip-chip CSP technology to white LEDs was Jiangsu Changdian, which has mature IC flip-chip technology. However, this technology has not been successfully promoted for unknown reasons, and the country has truly created a gold-free line. The new trend of CSP packaging is Guangzhou Jingke Electronics. It is understood that at present, Jingke is the first enterprise in China to successfully apply flip-chip soldering technology to LED chips. At the same time, it has applied for core patents and authorized multiple flip-chip soldering technologies in the US and China. At this year's Guangya Exhibition, Jingke Electronics also presented the latest CSP products under the theme of “China Core, Jingke Dreamâ€. And, since the beginning of this year, Foshan Guoxing Optoelectronics has gradually introduced the CSP high-power LED device of the NS-CSP 1010 series. It is understood that this series of devices uses the industry's advanced ceramic film substrate (C-TFS) package architecture to achieve high-package LED packaging, which can be used in backlight, high-density lighting, projection equipment, high-end indications, etc., starting in the second quarter of this year. Supply. "National Star's CSP device can achieve high-package LED packaging, and this series is also one of the world's smallest watt-level power CSP LED devices, with a peak power of 3.5W and a size of only 1.0*1.0*0.4. The effect is 130lm/W@6000K, and the thermal resistance of the device is ≤5K/W.†Dr. Xie Zhiguo, deputy director of R&D Department of Guoxing Optoelectronic White Light Device Division mentioned. In addition to the domestic large packaging factories are quite optimistic about this technology, Taiwanese companies also show great enthusiasm for this technology. For example, Lianjing Optoelectronics Co., Ltd. was the first LED packaging manufacturer in Taiwan to announce mass production of CSP packaging products. In addition to the Mercury CSP1515 series of high-power chip-scale packaging products introduced in 2013, the company recently introduced CSP dual/quad color packaging. Device. “The company has developed CSP products according to market demand. It can maintain high luminous efficiency and thermal stability under high driving current, and can reduce the package size to only 16mm×16mm, which can provide users with higher requirements. The development of luminaires is flexible and helps to explore emerging applications such as endoscopes, etc. According to Taiwan's packaging manufacturer Lite-On. Backlight continuation GGIILED backlight research data shows that the direct-type backlight penetration rate has not increased unexpectedly, from 57% in 2014 to 59.5% in 2015, and GGII also expects this data to further increase to 68.5% in 2019. This CSP will have a large room for development in the field of backlighting. Recently, Zhou Xuejun, Marketing Director of Lumileds Asia and Xie Mingxun, Deputy General Manager of Jingyuan Optoelectronics R&D Center, also pointed out that CSP will be applied to LED TV backlight in 2016. At the same time, many well-known people revealed that CSP will be the first to be applied in the field of backlight and high power next year, and it has great possibilities. "According to the current situation, CSP has become the development focus of the 2015 direct-lit backlight design. Its biggest advantage lies in cost saving." Xie Mingxun mentioned that the CSP product of Jingyuan Optoelectronics has been used for a long time in the backlight field and is very mature. The product. It is reported that due to the high optical density and high light intensity of CSP light source, the current CSP products have been widely used in large-angle light source products, such as television, mobile phone backlight, etc., but the most worth mentioning is the TV backlight field. Because in the current TV application, the brightness of the traditional medium power device can not meet the requirements of 4K TV. According to the crystal element, compared with the traditional package structure, the CSP size is reduced by about 34%, and the cost can be reduced by 20%. Although the CSP has a high single cost, the five-sided illumination can be omitted in the direct-lit backlight field. The secondary optics problem can reduce the number of pixels and reduce the distance, thus making the body thinner and reducing the overall accounting cost by 1/3. "Since the beginning of this year, the need for manufacturers to reduce costs has become imminent, so the role of CSPLED in the LED industry is becoming more and more important. It can be said that it has become the wisdom of the majority of LED manufacturers to reduce manufacturing costs, very small But it has the same luminous flux, and the chip requires less raw materials. According to Zhou Xuejun, CSP LED can reduce the cost of traditional LEDs by nearly 40%. "In the original 2835 or 5630 device, it was the Korean TV backlight that simplified it to the extreme. At this time, mass production, and finally this technology penetrated and occupied the lighting market, and it is expected that CSP will have the possibility to go the same way. According to industry insiders, the proportion of new TV-type CSP backlights next year will probably reach 50%. Moreover, many LED experts have agreed that after CSP L ED is applied to TV backlights, it will be applied to lighting fixtures in the future, but the time points predicted by experts are different. For example, Zhou Xuejun estimates that CSPLED will In 2016, it began to be applied to lighting fixtures, and Xie Mingxun advocated that the application of CSPLED in lighting fixtures should start in 2017. “At present, there are industry rumors that LG Display and Samsung are using CSP L ED instead of traditional LEDs, which are very interesting as backlight applications for LCD TVs, while CSP L ED is more closely arranged, with higher brightness and the number of LEDs used in TV backlights. Less, once LGDisplay and Samsung decided to use CSP LEDs as TV backlights, the market penetration of CSP LEDs will increase significantly.†Zhou Xuejun finally mentioned. Broad prospects In addition to the great potential in the field of backlighting, CSP technology also has unparalleled advantages in the high power direction. "Because the same device volume can provide more power, therefore, in the high-power lighting products, the stability and cost performance of the CSP light source have a small advantage." Hangzhou Huapu Yongming general manager Chen Kai told reporters. It is understood that as the first lighting application enterprise adopting CSP technology in China, Maple Yongming has full representation in the application of CSP street light source. “Overall, when applying CSP light source, although it is slightly more difficult in terms of processing technology than ordinary light source devices, considering various factors, it still has an advantage in cost.†Chen Kai mentioned These advantages, in the future, CSP devices will inevitably be widely used in the street lamp industry. But the problem is also here. At present, most commercial lighting is biased towards small and medium power, and CSP is still mainly focused on high power. Up to now, only a small number of companies such as Toshiba have introduced medium and small power CSPs. With the increase of SMD placement equipment and process precision, CSP can be extended to small chips, and will be marketed with medium package in medium power LED applications. competition. "The advantage of CSP devices is that the simplification and miniaturization of individual device packages can reduce the material cost of each device as much as possible. At present, the market with the greatest potential of LEDs is mainly concentrated in the field of commercial lighting and home lighting, if CSP technology can break through The cost problem has been successfully extended to the small and medium power field, and its market space will be very huge in the future.†Shao Jiaping, general manager of Career China, mentioned. In recent years, with the continuous maturity of LED technology, various new materials, new technologies and new models have come to the fore, and the industry transformation and upgrading are also accelerating. At present, CSP unpackaged chips have been applied to backlight screens, general-purpose lighting, etc. It is believed that with the continuous innovation and improvement of CSP, the future will have more room for development in flashlights, car lights, display screens, etc., creating greater value. .
