Revolution? Seoul semiconductor production WicopLED

China LED network news] to 2019, Seoul semiconductor to become the largest manufacturer of LED. On September 15th in Shanghai Jinqiao Marriott Seoul semiconductor LED products conference, chairman Li Zhenxun to the more than and 30 industry and the mass media.

"Every year, Seoul semiconductor input R&D fee equal to 10% of revenue, has more than 10000 patents worldwide have to now, and was named by IEEE No.1 Patent power said" Mr. Li Zhenxun, "we are not selling products, but to provide our value to customers".

Seoul semiconductor has been attached great importance to the innovation of the enterprise, creating value through research and development in the LED industry, launched the first AC LED Acrich series, and GaNon - GaN nPola LED, to explore a new direction for the technical innovation of LED industry.

Korea Seoul semiconductor new LED package Wicop

But this is obviously not the world's first chairman Lee set goal all the more solid confidence, followed is clearly the protagonist - Seoul's first global semiconductor new product launches today launched Wicop.

Traditional LED encapsulation structure

WiCop is a more simplified design for CSP. Why support, why solid crystal, why the gold line? What happens if you take these? So, the new wafer class LED was born, he is Wicop. Nobel prize in physics is also the chief consultant of Seoul semiconductor in the visit to the company, the company pointed out that the use of reverse thinking to do the invention of the. Wicop is obviously the product of reverse thinking, Seoul semiconductor display Wicop does not require solid crystal, no support, no need for welding wire, just press the top of the chip fluorescent film, a new generation of LED became.

In the product planning of Seoul semiconductor, Wicop and Acrich, nPola and UV on behalf of the LED direction of the next four strategic products ViOLEDs, Wicop why enjoy such a respected position?

According to reports, Wicop because of the characteristics of the packaging, the volume is very small (1.5mm * 1.5mm), and the light-emitting angle is very large (120 ~ 150), so the need for the application of the two optical design are very applicable.

When in use, the chip electrode is directly welded to the PCB, the heat sink is very short, so the thermal resistance is very low, the drive current can be more than twice that of the ordinary package, and the 2500lm / Usd ratio of the ultra high lumen can be realized.

The technology of the direct fitting of the fluorescent film to the chip is more able to achieve a high degree of uniformity of light and color, to overcome the shortcomings of traditional phosphor technology can not accurately control the distribution of color coordinates.

Because of the great compression of the process, a substantial savings in packaging materials, mass production after the Wicop cost is also very advantageous. Therefore, from the beginning of 2012 the development of Wicop, from the beginning of 2013 has been widely used in the straight down TV market, and gradually replace the 2835 to become the main components of TV backlight specifications.

Now, after 3 years of development, the actual use of verification for 2 years, Seoul launched a more mature and stable full optimization of the Wicop2, I believe will become the same starting 56302835 once using the lighting market huge production capacity and price advantage from the accumulation of the backlight market quickly.

"I believe we will soon see in the side by Seoul semiconductor lighting products Wicop2 production of" Seoul vice president of semiconductor, semiconductor and Seoul Greater China general manager Mr. Li Jianming said "Seoul semiconductor adhere to 23 years focused on LED, now Wicop2, this let us proud of by products, once again leading the technology trend LED innovation".

Wicop's advantage is so obvious, but the production process is quite simple. According to Mr. Li Zhenxun introduced the production process of Wicop, do not need to complete the solid crystal machine, welding machine, glue machine equipment that is no longer required to support gold and all kinds of glue, this new process of LED industry may be disruptive. As a result of such a trend, Seoul semiconductor has long been no longer invested in these devices, but also do not produce these materials may be eliminated.

For the packaging plant, this may not be good news, with the proliferation of Wicop technology, the future of the packaging plant in the value chain may be replaced by most of the status. Seoul semiconductor packages have a huge business, the popularity of Wicop makes the original business will inevitably be affected, asked on this issue, Mr. Li Zhenxun, for example, once NOKIA has more than 40% mobile phone market share, then Sony Ericsson, Motolora have to follow NOKIA as the goal, but when Jobs put them the integration of mobile phone and computer, intelligent mobile phone when there such a product, whether NOKIA or Motolora have disappeared, only innovation + creative to become the trend of changes in the market leader, only without the fear of change, this is also the Seoul semiconductor will continue operating income into 10% R&D.
