Experience of relatively stable in the first half of the LED industry is strong in the third quarter to "boom" opens in the second half of the market.

High yield research institute (GGII) that LED the global LED industry is entering the "China enterprise" leading the development of the cycle. In the second half of the LED industry is still facing greater opportunities and risks coexist, of course.

As is still in the rapid evolution of technological innovation, new technologies, such as CSP, maturity of the new technology are rapidly improving.

The current CSP products have begun to mass applied to the large size backlight products and mobile phone markets such as flash, small batch used in automotive lighting, automotive lighting market in 2017 is expected to form scale shipments.

In addition, the CSP in high power special lighting, adjustable lighting, explosion-proof lighting such as conforms to the characteristics of CSP applications will be preferred. A lot of the personage inside course of study thinks CSP may enter the rapid growth in the coming years,.

High yield research institute (GGII) LED is expected, the next three years of CSP, inversion products market share will reach more than thirty percent, at the same time will also be a China LED packaging companies full beyond the best opportunities for foreign companies.

Mass production still needs time

Since the second half, there is no denying the fact that in CSP boom has spread the LED packaging market.

Trillion chi energy saving lighting co director deputy general manager hai-bin zheng said, "in foreign countries, such as Japan and South Korea department of CSP in TV backlighting and flash on the market have a higher market penetration in the lighting market is also widely stage. At home, because the equipment and materials for corresponding development relative lag, so domestic CSP basic are in the stage of product small batch production, marketing."

Domestic CSP products haven't started mass production, there are three factors.

Crystal tyco electronics, vice President of Song Dong analysis, first, the early many enterprises without special equipment for CSP, and the precision requirement of backlight field of CSP is very high, the requirement of equipment is also very high;

Second, human factors, some lamps and lanterns manufacturer directly with chip manufacturers cooperation, make your own packaging, saves packaging companies, has caused many packaging business failures;

Third, CSP is not yet formed big modulus gauge production, mainly technology has some no breakthrough process cost is relatively high, resulting in the short term, CSP compared with traditional mature packaging technology is not very strong advantage, the traditional technology with case for reference, the price is cheap, it is a big challenge for CSP.

In fact, after nearly a year of development, the CSP market also appeared a lot of positive changes. Product performance is improved and standardized specifications, for example, gradually formed, the perfection of form a complete set of industrial chain, etc., all these show that CSP market is gradually mature.

Trillion says, "to promote these changes are the main factors of CSP market prospect is being more and more people, at the same time a CSP products with high photosynthetic efficiency, low thermal resistance performance and recognized by more and more people in a particular area has an irreplaceable advantage."

At the same time, the internal layout of the CSP enterprise groups are also growing. The past only Lumileds, Japanese and a batch of LED enterprises to do foreign CSP, CSP in recent years in Taiwan LED enterprises gradually grow up and quickly spread to the mainland.

East son photoelectron sales director tan gang said, "as the size of the CSP industry chain gradually increase, but also will attract more suppliers to participate in, so as to promote the scale of production capacity, improve lighting and the decrease of the cost of raw materials, accelerating the ascension of the CSP price."

CSP cut into inevitable in the future

As is known to all, in the LED industry, the price has always been a sensitive topic. CSP as a new product, its price is controversial.

Current CSP price according to the product demand, compared with the general lighting market products or high, is not accepted or accept difficulties; With existing products in backlight market prices basically unchanged, but in a flash and the existing products, automotive and other market prices have an advantage.

"As far as the current trends, nearly a year of CSP products price has been a larger decline, at the same time as domestic production equipment, wafer and other materials supporting the development of the supply chain, CSP also will be a sharp drop in price in the future." Trillion chi said.

Current CSP products are mainly used in car lights, display backlighting, flash and other relative special application market, these markets are strict with the quality, the price is basically can be accepted by the user.

Tan gang said, "at this stage CSP has not formed enough scale production, flip chip prices relative to suit the chip price is high, but from the perspective of the market of foreseeable, CSP will usher in the large-scale development in the future, as well as the increasing improvement of the chip photosynthetic efficiency cost also will be slashed, as the price is bound to be the core material and downward adjustments."

Song Dong were relatively cautious, "mature technology price will naturally tend to be steady, price, the customer is a natural choice, all products will eventually passed on to the market to decide."

Technical problems still exist in CSP

CSP market demand is gradually released, but the technology is not fully mature this is unavoidable, the existing CSP technology also exists certain difficulty.

Song Dong proposed that "enterprises still need to hard to perfect the technology improve, highlight CSP really high density, high photosynthetic efficiency, small size advantage."

How to improve the luminous efficiency of their products, reduce the heat dissipation area, reduce the cost of shape structure and a series of problems to be solved.

East son optoelectronic always take the customer as the core, to join hands in LUMILEDS, bridgelux, three Ann and other international well-known enterprises continuously develop products with core competitiveness for our customers.

According to tan gang, at present there are mainly 1005, 1510, 1515, 2020, 2525, etc. Series of products, covering 0.2-25 w power range, applied to the adjustable light to shoot the light Flash lamp, backlit display, and other products, and in automotive lighting market introduced a series of 10-25 w high power single CSP products.

In performance, due to the CSP product to remove the reflection cup, its light output affected by certain, limited brightness increase, so the present technological development trend of CSP products in addition to improve the reliability of the product itself, more important is to promote product brightness.

On craft, the CSP production part of the process are manual or semi-automatic, so in the process of CSP products stable performance is the development direction of packaging automation, but also contains the SMT assembly and test the full range of automation.

Trillion chi CSP products according to the characteristics of energy saving lighting co mainly divided into three broad categories: five surface light structure of CSP, single out the light structure of CSP and high-pressure CSP, according to the size to distinguish mainly for: 1010, 1313, 1515. Its characteristics are mainly high COA on backlight optical design features, special silicone heat-resistant, special optical structure.

"CSP products in August has already begun in batches for some international companies OEM business." Trillion chi told leds.

CSP market or will be more competitive

At present the main factor that restricts the CSP product cost for high precision production and testing equipment, wafer and other materials supporting the development of the supply chain has not yet formed the scale, the domestic CSP production manufacturer's equipment large-scale investment is high, such as chip raw material is not into large-scale production, raw material cost is high.

Under such market background, the signs in the chi energy saving lighting co on the one hand, through the strategic cooperation with raw material suppliers, assist supplier to standardize materials development, directly reduce the CSP products cost; Through the depth of communication with the customer on the other hand, in the beginning of the design and development of solutions to give full technical support, and ultimately achieve CSP products total cost optimization of the system.

As domestic production equipment, chips and other materials supporting the development of the supply chain, in the next few years CSP in the decline of the inevitable price, until the price 20% to 30% of existing products.

Trillion chi predicted that "the CSP products will be fully in many different areas of promotion and application, will let the CSP products on the market becomes more competitive and aggressive."

As the industry continues to form a bullish consensus, many companies are moving in the CSP plate mounting technology investment funds. Luminous efficacy, production scale, product yield of SMT placement, such as ratio of problems will gradually improve, predicts 2017 encapsulation of CSP production is expected to reach 6 billion yuan of above.

"East son photoelectron planning of xiamen production base in 2016 will begin in early 2017 into production, production capacity will be 3-4 times bigger than now, on the scale of production to labor costs and equipment costs diluted, and use the scale effect on the chip for the price of a certain active for cost control." Tan gang mentioned at last.
