The CSP LED era is coming, LED industry and technology will show a diversion trend
In recent years, the development and shipment of CSP products by LED Taiwan factory has been gradually fermented in Japan and Europe and the United States. The author recently interviewed Chen Zhengquan, general manager of New Century Optoelectronics, to analyze and explore the readers of the new century. What are the advantages of CSP wafer-level packaged LED products developed by Flip-chip technology and the niche market that can be applied in the future.
The true advantage of CSP LED product structure
General Manager Chen Zhengquan pointed out that the new century began to lay out the flip-chip LED technology independently developed many years ago, and has applied for relevant patents at home and abroad. The core patents related to CSP and CSP are more than 100, and the existing products are out. The follow-up cooperation and cooperation of the goods and the customers have indeed brought into play the inherent advantages of CSP packaging products and the technology of day-to-day adjustment. However, CSP package products are not intended to replace the existing LED package supply chain, but to give the industry the opportunity to move towards different industry trends.
He further explained that traditional LED packages come in many forms, from wire-bonding, substrate, and board modes used in high-power LEDs to PLCC and COB packages. The industry has developed many applications for LED backlighting and LED lighting. The package form is used on the market. When it is developed into a CSPLED package, this is an upgrade and change of the LED package structure, which solves the problem of the light receiving angle, reliability, brightness, and mechanism strength of the conventional LED package under the cost saving.
There are some CSP LED products on the market, only the flip chip structure, plus the phosphor sealant, it is sold in the style of CSP products, but he thinks this is not really good CSP package, because this kind of LEDs do not have enough structure to protect the LED chips themselves. The reliability and reliability of the products will encounter problems. There are also different voice feedbacks in the market, forcing manufacturers to try to improve related designs. The CSP product structure adopted by New Century Optoelectronics integrates the brackets through the Wafer Level Package process, and has a fairly good optical design space. With a smaller chip area, it can compare the reliability of PLCC package products. And there is no need to wire, the advantage becomes a smaller wafer area, a process with a bracket to strengthen the structure and a wafer stage, and the thickness of the product is much thinner than the existing commercial products.
More importantly, the new century has spent a lot of effort and energy on the planning and research and development of related yields and processes. Therefore, in the wafer-level packaging process, it has achieved very good yields. The performance on the machine has been very good, and the response to the customer is also good.
Product design solutions (Design-in SoluTIons) and optimized luminous efficiency per unit area
Chen Zhengquan explained that the biggest advantage of CSP LED technology products is the customized design made by customers in the new century. Due to the optical design, the optical design of CSP LED products is smaller with the bracket, the product is smaller, and the unit area of ​​the product is lumens. A substantial increase can increase the design flexibility of the product. From the end customer requirements, product thinning, increased optical design flexibility, and stable product reliability, CSP LEDs are also able to provide design solutions (Design-in SoluTIons).
What is the product design solution for the new century?
In terms of LED flashlights, we know that the representative works on the market are LED high-power chips from American manufacturers. As long as the optical lenses are used together, the structure of the LED flashlights is well completed, and the process of ship-to-ship and customer use is very smooth. However, the current LED components are relatively large. If LED flashlight manufacturers want the same wattage, smaller LED component size, and farther illumination effective distance, what should we do? In the new century, there are solutions in this market, which can provide smaller sizes, such as a quarter of a white chip, so that the application of the projection and illumination source has a good optical design, and the light collection can be better. The luminous efficiency per unit area is also good.
In terms of LED backlighting, the new century has already provided customers with ultra-thin, CSP LED components with a thickness of only 0.3mm (the current general specification is 0.6mm), which enables the latest thinner direct-lit LCD TVs to adopt this LED package. Improve the problem of thinness and efficiency. On the other hand, part of the edge-lit LCD TVs already have branded manufacturers, using thin Corning glass light guides, and the new century can also be equipped with the new century 1810 CSP LED products, the size is very small, so the TV can It is made thinner, and the current is 200mA, the voltage is 3V, and the luminous flux is 72lm under the test temperature of 25°C, which is quite good.
Non-replacement of existing LED package supply chain, but to industry diversion
For the new century optoelectronics, this CSP LED is not to replace the existing LED packaging supply chain. As the LED industry faces market changes, the industry and technology are diverging. Existing industries have developed economies of scale, and large and large manufacturers exist. Small manufacturers need to find their own market operations and sales.
CSP LED products are used in the traditional backlight and lighting market. Although they will compete with the original product price, in the special lighting and automotive lighting market, customers have higher design flexibility. Special commercial lighting, patio lights, projection lights, flashlights, mobile phone flash and other projection products require optical design, so the use of CSPLED products can achieve the light-receiving function, the luminous flux per unit area (lm / mm) can achieve the best use.
With the development and cultivation of the automotive market, the new century has also passed the TS16949 certification, and has already cut into the aftermarket lights (AM) market of large factories at home and abroad, and with the company's experience in automotive LEDs and product structure advantages, and The cooperation design of the lamp manufacturers has a stable order and will help the future development.
In the new century, we provide manufacturers' customer solutions. If customers are satisfied, the new century can be supplied from chips and packages to module solutions. It will also cooperate and cooperate with different LED packaging manufacturers. In other words, the business strategy of this century is flexible. It is not to replace the LED packaging factory, but to have more in-depth cooperation with LED packaging factories and terminal application manufacturers. Each of them has a division of labor, and through the product structure such as CSP, find the appropriate niche market and play this aspect. The biggest synergy.
In the future, the proportion of shipments of CSP LED packages will be higher and higher in the new century. The company's traditional LED revenue will be less, although there will be no significant growth in overall revenue in the short term, but long-term and long-term The experience of different customers' cooperation and cooperation, the introduction of design thinking solutions, can enable New Century Optoelectronics to find a suitable long-term operational route to a better product margin portfolio, for LED manufacturers, it is also worth exploring the direction and issues .
