The industry's big brother Kan CSP leather package life?

In recent years, CSP packaging has been at the cusp of public opinion. With the growing number of investment companies, CSP chip packaging is considered to be the inevitable trend of the development of LED. However, CSP market in the end how progress? In order to uncover the mystery, the reporter interviewed a number of industry heavyweights, for you to show the real CSP industrialization process.

Bright sharp (Lumileds) Asia market director Zhou Xuejun: CSP packaging new trends

CSP (chip level packaging) in the semiconductor industry has been around 20 years of history, and in the use of light-emitting semiconductor, it is a new thing occurred in the past one or two years. At present, CSP is gradually being used in the field of mobile phone flash, display backlight, and general lighting (such as the whole week replacement bulbs, panel lights, street lamps, etc.).

In fact, Lumileds's CSP products as early as a year ago has been widely used in a well-known mobile phone LED flash. In the display backlight, the field of general lighting applications, we are based on CSP's complete product portfolio is also rapidly forming. Now, many customers have a great interest in Lumileds CSP, some products through the sample, has entered the stage of product design, is expected to focus on large-scale market demand will be concentrated in the next year.

Following the track of the development of semiconductor devices, LEDs is gradually developing towards miniaturization and miniaturization. CSP to small size, low voltage, good heat dissipation, high light out of the advantages, represents the direction of the evolution of LED packaging devices, will become one of the major trends in the future high-power LEDs.

CSP packaging costs can be significantly reduced. As far as the device itself is concerned, the CSP simplifies the packaging process and reduces the consumption of materials, eliminating the traditional process of solid crystal, wire laying and glue filling, and does not need the material of gold wire, bracket, solid crystal glue, substrate, etc.. In addition, CSP can simplify the supply chain management, improve the flexibility of the lamp design, and reduce the cost of the corresponding system. CSP light area is small, in the need of high luminous flux density and high intensity lighting applications, the advantages are obvious.

Following the LED phone flash, CSP application in the field of backlight is also gradually expanding, the future will also be promoted to the general application of the field of large-scale lighting. At present, if the CSP to get a large area of application, relative to other categories of LEDs, the need to reduce the cost of the system, improve the performance of the system has more advantages, and the formation of a complete matching system. At the same time, the application of product manufacturers need to master the CSP patch technology, which requires a process. Due to the diversification of the demand for LED lighting market, the next long period of time, CSP packaging products will be SMD, COB and other packaging forms of LEDs coexist.

With the gradual expansion of the size of CSP applications, device costs will be further reduced. In the technology matures and cost-effective to enhance the premise, CSP will be a large number of lighting companies to adopt and apply.

Lumileds as the LED flip chip pioneer and the world's first mass production CSP manufacturers, will continue to increase investment in the field of CSP, to help customers get and maintain a leading edge.

Tang Guoqing, general manager of Samsung LED China: high quality price CSP winning way

During this year's Asian sub show, Samsung launched the second generation of CSP products, inherited the first generation of CSP low thermal resistance, high current, high luminous flux and high reliability and other advantages. Its shape is more compact, 1.2mm x 1.2mm size than the first generation of CSP volume reduction of about 30%. It uses advanced multi - face fluorescent powder coating technology, can do five - side light, will improve the luminous efficiency of about 10%. Now, the second generation of CSP has entered the stage of mass production, and the first generation of CSP shipments reached hundreds of KK, widely used in the field of backlight and lighting.

CSP industry in the emergence of a number of voices of doubt, it is normal. Any new thing comes out with some opposition, because it also needs a process of continuous improvement. CSP will not be popular, only to the market to verify is the most appropriate.

Now, CSP chip technology in the hands of the hands of the enterprise, once the popularity of industry will be from the "chip factory + + application package factory" mode to "chip factory + application business model, save the package link, shorten the chain, it will have a certain impact on the packaging enterprises.

At present, manufacturers competing layout CSP technology, because it is consistent with the future development trend of miniaturization of LED devices. First of all, CSP will direct the fluorescent powder covering on the chip, simplifies the production process, reduce production costs; second, without support, resistance is greatly reduced, the same volume of the device can provide greater power; third, packaging form smaller, closer to the user terminal point light source, lighting design is more flexible, brings more convenience the application of manufacturers.

Although, at present, CSP technology is more mature in the field of backlight, but the ultimate goal is to apply to the lighting. Some customers will inevitably talk about price. Some people prefer to simply than the price, the emphasis on cheap beauty, which is actually a misunderstanding, there is no reasonable profit, how to survive, how to develop? The industry continues to move forward, the need to continue to promote technological innovation, quality and price is king, but also the fundamental way of brand development.

Elec-Tech chip R & D vice president Mo Qingwei: the industry chain collaboration build CSP ecosystem

Last year launched the "Polaris" series of CSP products, and now the monthly shipments have reached the KK level, which is used in the TV backlight, outdoor lighting and commercial lighting
