When did CSP break out in the lighting field? See the 5 stages of development

At this stage, CSP backlight in the field of LED, the market share of the mobile phone flash market is to maintain growth, but there are still few enterprises in the field of lighting to achieve mass production.

Because the light has not yet met the requirements? Or the cost is still high? What role does the future play in the lighting market?

Taiwan Jingyuan chip giant Au Optronics Co is one of the few companies can reach CSP in its earlier production, R & D Center Deputy General Manager Xie Mingxun said, "said CSP LED a monthly production capacity has reached KK level. "We EPISTAR R & D center innovation application group associate of Mr. Xu Jialiang, there are a lot of understanding the current situation and market prospects for the development of CSP.

CSP only in the field of backlight and flash?

According to the rapid development of the mobile phone CSP backlight and flash in two years in the field of Xu Jialiang that is similar to CSP and the development trend of the original traditional LED, such as 2835, 3030 and 5630 are first used in the field of backlight, backlight field because conversion speed, in mature in this field will only be used in other fields.

By virtue of the excellent performance of the backlight in the field, the current LED companies will be a lot of CSP applications in the field of lighting, the first batch of small test of its reliability, and then mass production of CSP. Reliability is the most critical and primary consideration for new products; two is the yield, which determines the cost of the product.

The CSP reliability and yield have been achieved, but the yield is not high, because a large number of application of many downstream customers dare not, they need from certain kinds of on trial and Application on the basis of stability.

"This is the general law of the development of new technologies in the field of LED: the backlight cut into the field of lighting, there is no technology can be used in the backlight and can not be used for lighting problems. Xu Jialiang pointed out, CSP cut into the field of lighting the biggest problem is the high cost.

This year by PHILPS and other international giants pulled a wave of low price means that the price of LED general lighting has been flat with the traditional lighting. In the field of lighting is based on cost in command, and in the backlight field it is not only the simple cost of light, but the entire design cost, so that the application of CSP in fast speed.

2016-2017 is expected in will be significantly increased in the backlight field, the outbreak in the field of lighting to the year 2017, and not all lighting market. At present, the industry has reached a consensus: CSP will not replace all of the packaging, it will be applied to the field to play its advantages, lighting may account for only a small part.

CSP is more suitable for lighting design which needs to be adjusted dynamically

Xu Jialiang analysis, the future can be easily adjusted by the CSP lighting design.

First, it can be applied in the field of commercial lighting with special emphasis on light intensity and angle adjustment.

The current window display more emphasis on the art of lighting, the need to match the changes in the sun to make a dynamic adjustment, it is difficult to meet the needs of the traditional lighting, but the LED can be changed to give people a visual feeling. To achieve the artistic effect of light, the light of the light to be small, easy to adjust the design angle.

At present, commercial lighting application more COB compared with the traditional package is easier to achieve this effect, but COB limited to monochrome, although the painting various phosphors have a variety of colors, but it is not easy to control the color change, and the application of multi CSP integrated COB can adjust to different color temperature.

In addition, the future can also adjust the scene CSP.

Because people are easy to be affected by the characteristics of the environment for home lighting put forward higher demand, according to the time and the four seasons.

Xu Jialiang for the development of CSP in the lighting field is summed up in five stages:

The first step is to test the water, let others agree that it has reliability;

The second stage is a large number of applications in other areas, the cost gradually reduced;

The third stage is the popularity of commercial lighting;

The fourth stage to intelligent lighting;

Finally applied to general lighting.

Because general lighting does not require too much technology, but a market to follow suit, the amount of the market is large enough, the cost is low enough, the reliability is high enough to be applied.

Chip companies have more advantages to develop CSP

Or is the traditional package of income does not increase profits cloud top pressure, packaging manufacturers almost big in this piece of blue ocean waters CSP.

In the face of this round of upsurge, Xu Jialiang positive attitude, the more people into this field, the more representative the opportunity to popularize this application. Because an application can be accepted, not rely on technology to convince some people, but rely on the market to convince everyone. "

Of course, the influx of enterprises also exacerbated the competition in the market, but compared with the packaging companies, chip companies in CSP is clearly more advantages:

Because the upstream chip to know the key production process, more easy to design the chip, it can be easily controlled, and the more downstream enterprises to get the more information. CSP research and development is not just a master of the chip, but from the end of the material, the chip to the package side, chip companies in this series faster. -- Xu Jialiang

But chip companies will do with the downstream packaging CSP customers conflict, squeeze out some of the customer market? In the face of doubts, Xu Jialiang said Jingyuan always uphold the cooperation with customers and common development concept, validation will assist some packaging factory CSP.

In addition to the domestic packaging plant
