In the first half of the year, the LED industry was strong in the third quarter with a “price boom†to start the second half of the market.
The High-tech Research Institute LED Research Institute (GGII) believes that the global LED industry is entering the development cycle dominated by “Chinese companiesâ€. In the second half of the year, the LED industry is still facing greater opportunities, and of course risks coexist.
As technological innovations are still evolving rapidly, the maturity of new technologies and processes such as CSP is rapidly increasing.
At present, CSP products have begun to be applied in large quantities to large-size backlight products and mobile phone flashlights. Small quantities are used in automotive lighting. It is expected that large-scale shipments will be formed in the automotive lighting market in 2017.
In addition, CSP will be given priority in areas such as high-power special lighting, dimmable lighting, and explosion-proof lighting that meet CSP characteristics. Many industry insiders believe that CSP is likely to enter a rapid growth period in the next few years.
The High-tech Research Institute LED Research Institute (GGII) predicts that the market share of CSP and flip-chip products will reach more than 30% in the next three years, and it will also become the best opportunity for Chinese LED packaging companies to fully surpass foreign companies.
Large-scale mass production still takes time
It is undeniable that since the second half of the year, the CSP boom has spread throughout the LED packaging market.
According to Zheng Haibin, deputy general manager of Zhaochi Energy-saving Lighting Co., Ltd., “In foreign countries, such as Japan and South Korea CSP, there has been a high market penetration in the TV backlight and flash market, and it is also widely promoted in the lighting market. Due to the relative lag of the corresponding supporting development of equipment and materials, domestic CSPs are basically in the stage of small-volume production and marketing.
The reason why domestic CSP products have not yet started mass production has three factors.
Song Dong, vice president of Jingke Electronics, first, many companies did not have CSP special equipment in the early stage, and the precision of CSP in the backlight field is very high, and the requirements for equipment are also very high;
Second, human factors hinder, some lighting manufacturers directly cooperate with chip manufacturers, do their own packaging, eliminating the need for packaging companies, leading to the closure of many packaging companies;
Third, CSP has not yet formed a large-scale mass production, mainly because there are still some breakthroughs in technology, which leads to relatively high process cost. For now, CSP has no strong advantage compared with traditional mature packaging technology. Traditional technology has cases for reference and the price is cheap, which is a big challenge for CSP.
In fact, after nearly a year of development, there have been many positive changes in the CSP market. For example, product performance has been greatly improved, standardized specifications have gradually formed, and the supporting industry chain has been improved. This indicates that the CSP market is gradually maturing.
Zhaochi believes that “the main factor driving these changes is that the CSP market prospects are being favored by more and more people. At the same time, the high light efficiency and low thermal resistance performance of CSP products are recognized by more and more people in specific fields. Has an irreplaceable advantage."
At the same time, the corporate group of domestic layout CSP is also growing. In the past, only a group of foreign LED companies such as Lumileds and Nichia were able to do CSP. In recent years, CSP has gradually grown in Taiwan LED enterprises and spread rapidly to the mainland.
Tan Gang, director of sales of Donghao Optoelectronics, said, “As the scale of the CSP industry chain gradually increases, it will attract more suppliers to participate, thereby promoting the scale of production capacity, improving light efficiency, reducing raw material costs, and accelerating the cost performance of CSP. ."
Future CSP price reduction becomes inevitable
As we all know, in the LED industry, price has always been a sensitive topic. As an emerging product, CSP's price is also controversial.
At present, the price of CSP is divided according to product demand. Compared with the products in the general lighting market, it is still high and is not accepted or accepted. The price in the backlight market is basically the same as that of the existing products, but the prices in the flash, car and other markets are relatively high. Existing products have advantages.
"As far as the current trend is concerned, the price of CSP products has shown a large decline in the past year. At the same time, with the development of supporting supply chains for domestic production equipment and wafers, the price of CSP will fall sharply in the future." Chi said.
The current CSP products are mainly used in relatively special application markets such as lamp, display backlight, and flash. These markets have strict quality requirements, and the price is basically acceptable to users.
Tan Gang said frankly, "At this stage, CSP has not yet formed sufficient scale production. The price of flip chip is relatively high compared to the price of formal chip. However, from the foreseeable market, CSP will usher in large-scale development in the future. As the efficiency continues to increase, the cost will also be significantly reduced, and the price will definitely adjust downwards as the core material of the chip is adjusted."
Song Dong is relatively cautious about this. "Technology is mature and the price will naturally stabilize. The price/performance ratio will come out. Customers will naturally choose, and all products will ultimately be decided by the market."
CSP still has technical difficulties
The CSP market demand is gradually being released, but the technology is not fully mature. This is unavoidable, and the existing CSP technology does have certain difficulties.
Song Dong proposed, "Enterprises must first work hard to improve the technology, highlighting the true high density, high light efficiency and small size of CSP."
A series of problems, such as how to improve the luminous efficiency of the product, reduce the heat dissipation area, and reduce the cost of the structural parts, need to be solved urgently.
Dongxun Optoelectronics has always been customer-focused, and cooperates with internationally renowned companies such as LUMILEDS, bridgelux, and Sanan to continuously develop core competitive products for customers.
According to Tan Gang, there are mainly 1005, 1510, 1515, 2020, 2525 and other series products, covering the power range of 0.2-25W, applied to dimmable spotlight flash explosion-proof lamps, backlight display and other products, and for automotive lighting. The market launched a series of high-power 10-25W single-sided CSP products.
In terms of performance, since the CSP product has removed the reflector cup, its light output is affected to some extent, and the brightness enhancement is limited. Therefore, in addition to improving the reliability of the product itself, the technical development direction of the CSP product at this stage is more important to enhance the brightness of the product. .
In terms of technology, the current CSP product production process is manual or semi-automatic, so the development direction of CSP products in the process is stable packaging automation, and also includes the full range of automation of SMT mounting and testing.
The CSP products of Zhaochi Energy-saving Lighting Co., Ltd. are mainly divided into three categories according to their characteristics: CSP with five-sided light-emitting structure, CSP with single-sided light-emitting structure and high-pressure CSP, which are mainly divided into 1010, 1313 and 1515. Its characteristics are mainly high COA characteristics in the backlight optical design, unique silicone temperature resistance, special light-emitting structure.
“CSP products have started to carry out batch OEM business for some international big companies in August.†Zhaochi told Gaogong LED.
CSP market competition may be more intense
At present, the main factor restricting the cost of CSP products is that the development of high-precision production and testing equipment, wafers and other supporting supply chains has not yet formed a scale. Domestic CSP manufacturers have high-scale equipment investment, such as wafers and other raw materials have not yet become large-scale. Mass production, raw material costs are also high.
In this market background, Zhaochi Energy-saving Lighting Co., through strategic cooperation with raw material suppliers, assists suppliers in standard material development and directly reduces the cost of CSP products; on the other hand, through in-depth communication with customers, in design and development At the beginning, we gave technical support to a comprehensive product solution, and finally achieved the total cost optimization of the CSP product solution system.
With the development of supporting supply chain of domestic production equipment, wafers and other materials, the price of CSP will inevitably fall sharply in the next few years, until the price of existing products is 20%-30%.
Zhaochi predicts that “CSP products will be fully promoted and applied in different fields, which will make CSP products become more intense and radical in the market.â€
As the industry continues to form a optimistic consensus, many companies are increasing their investment in capital technology to the CSP sector. Product light efficiency, capacity scale, SMT placement yield, cost performance and other issues will gradually be improved and solved. It is expected that the packaging output value of CSP is expected to reach more than 6 billion yuan by 2017.
“The Xiamen production base planned by Donghao Optoelectronics in 2016 will start production in early 2017, and the production capacity will be expanded by 3-4 times compared with the current one. The labor cost and equipment cost will be diluted in the scale production, and the scale effect will be used in the chip. Strive for a certain price to take the initiative to carry out cost control." Tan Gang finally mentioned.
