LED packaging is highly integrated, and EMC becomes a new force in the packaging market

In recent years, with the rapid drive of new technology, new materials and new technology, great changes have taken place in the market pattern of LED packaging. In order to adapt to the development trend of device miniaturization, the LED packaging form continues to be highly integrated, and EMC LED packaging has become a new force in the packaging market in 2016. Now, this new force is rising. The main power of the EMC packaging scale continues to grow, the platform packaging enterprises and domestic LED manufacturers actively expand the EMC capacity, and improve performance to the high power market. At present, EMC packaging is to seize the market with ceramic packaging on the one hand, and on the other hand, it is necessary to deal with the raid of PCT. EMC expansion to large size, gradually moving to the outdoor market mainland lighting plant in the beginning of the LED lighting, in order to reduce the single use of LED, to reduce the maintenance cost after shipment, and turn to high power, high brightness LED, but 1W above the excellent heat dissipation of the ceramic LED is almost covered by the European and American factories, its price is The mainland Lighting Factory is on the high side. As a result, the mainland lighting plants continue to look for alternative materials, and the technology of EMC as a package scaffold has become an excellent choice to improve the cost performance. Wu Sen, a senior market manager for solid-state lighting of OSRAM photoelectric semiconductor, said that the development trend of the packaging form in the lighting market in the last two years is that the medium and small power products will be encapsulated with PPA or PCT; the medium and large power level products have been widely used in EMC packaging, plus the traditional ceramic packaging of large power LED, and COB package. The application of EMC in medium and high power products enables LED products to better achieve small size and high power. Because from the power point of view, EMC has a mature patch process; from the structural point of view, EMC has better encapsulation integrity and is easier to light through the two optics of the lens. In recent years, the packaging of EMC has been greatly developed in indoor lighting, especially the high and low cost of medium and large power products represented by 3030. In the first two years, the main model of EMC3030 was introduced by the packaging enterprises such as Michael, sky electric, Hongli Zhihui, Ruifeng optoelectronic and Liyang shares. Nowadays, EMC's products are also expanding to large size, and the application range is gradually extended from medium power to higher power range. At present, in addition to 3030 EMC in the market, there are mainly 5050, 7070 and other models. Zhang Luhua, marketing director Zhang Luhua of Shenzhen Michael optoelectronics Co., Ltd., said: "at present, the EMC products in 20W have achieved full power coverage, EMC 5050 light efficiency can reach 160lm/w, can replace 3-7w COB products, can save about 30% of the light cost." As the first domestic enterprise to enter the EMC packaging market, the present day electric power electronics has made EMC 5050, 7070, 1A1A or even larger size to replace the low watt COB products, and the price is affordable. In this year's Guangzhou International Lighting Exhibition, the EMC products also made 25W products, and brought new HD EMC products to replace the COB below the traditional 3000cm, mainly for high-end home and commercial lighting market. Due to the advantages of material and structure, EMC products have the advantages of high heat resistance, anti UV, high integration, large current, small volume and so on. Among them, the performance of anti UV has been greatly improved, which makes the application field of EMC products expand from high-end business to outdoor lighting. In recent years, EMC has been widely used in outdoor and replacing traditional high-power products. It has become an important member of the middle and high end patch market, especially in the fields of outdoor lighting such as industrial lights, street lamps, and lighting lamps, and high end backlighting. Jing Yicheng, the product development manager of Fujian Tian Dian optoelectronic Co., Ltd., said that the EMC package is based on the indoor application and is gradually moving towards the outdoor market. PHILPS launched the Sirius module three years ago, representing the EMC packaging product to enter the street lamp market. After three years of fermentation, the performance of the product has been relatively stable. At present, many manufacturers have realized the production of mass production, which greatly reduced the cost of outdoor lighting and the initial investment in the project. Compared with the PCT, the EMC value chain is not mature in the market. The EMC packaging products are mainly concentrated in the medium power, and the power can be reduced to 0.2 to 0.5W. To the high power direction, it can be gradually applied to the outdoor fields such as street lamps, industrial and mining lights and so on. Before this, this is the market of ceramic packaging LED. However, when EMC struggled to snipe the ceramic LED market, the PCT scaffold material was improved by the manufacturer, the driving power was pulled from the past 0.8W to 1 to 1.2W. Apart from the distance from the PPA support, the market of the original EMC product was cut into the market of 0.7 ~ 1.2W in the original EMC products. Industry insiders say that EMC LED accounted for 10% of the device's share in 2014 and 20% in 2015, but a lot less than the PCT - based SMD 2835. Today, SMD 2835 obtains most of the small and medium power market, mainly because of its high cost performance. In the application of small and medium power, PCT is more cost-effective than EMC, because of its value chain optimization, because PCT has made a promotion on the basis of PPA. PCT can make full use of the mature value chain relationships of PPA, such as suppliers, enterprises themselves, associated support, and downstream customers. As far as PPA and PCT are concerned, they are thermoplastic materials, which are squeezed out of the injection molding machine, that is, they use the scaffold forming machine. In other words, from PPA to PCT, the packaging manufacturers do not have much input on the equipment. EMC because of the different materials and processes, from the molding machine, to the overflow, cutting equipment, the light detection machine needs to be re purchased, which requires a lot of cost, but also blocked most of the packaging plant into the EMC LED packaging field. Compared with PCT, the immature EMC value chain is reflected in the price of the product, in addition to the input of the equipment. In performance and light, EMC is really better than PCT and PPA in performance and light efficiency, but in price, EMC supports are several times more expensive than PCT, and at least 10% of the finished product will be more expensive. In the future, the cost will be reduced. In the future, as technology, material performance and preparation technology tend to mature, the popularity of EMC packaging products in the terminal market will be further promoted. At this stage, EMC packaging manufacturers should try to reduce the cost of their systems and optimize the industrial chain by improving technology and improving technology. For example: using the same process system, the sky power uses black EMC as a super small 1010 lamp, which is used on high density and high contrast display screen, and the reliability can reach the MSL1 level. The cost of EMC products has the advantages of high cost performance, high reliability and free combination compared with other light sources. However, the market share of the application growth is slow, mainly due to its high cost. In fact, the main challenge of EMC packaging is in support production, because the support is highly integrated, and the difficulty of production is higher than that of ordinary common stents. At present, the domestic enterprises that can master the technology of EMC scaffold production are not much, most of the domestic packaging plants are buying EMC support packages, only a few enterprises such as the electric power and electricity and the smaid produce their own EMC stents. Zhang Luhua said: "Michael has achieved the scale production of EMC series stents through the self-developed support gas tightness technology, which is the first batch of EMC series of packaging manufacturers on the market, and the products can replace the same specifications of imported products." In the cost of EMC scaffolding, material accounts for 20%-30% of the cost of scaffolding. The metal frame used in combination needs to be used to the etching process, accounting for about 60% of the cost of the scaffold. Among them, PPA/PCT is all used for stamping copper, while most of the EMC is etched with silver plated copper, which is 3~5 times the cost of the etching process. The price of the material also makes the cost of EMC high. EMC is the abbreviation of Epoxy Molding Compound, which has been used for twenty or thirty years in semiconductor packaging and is very mature. But the EMC used in semiconductor packaging is black, and on the LED, the problems of light, reflectivity, yellowing and light failure are made white, and a new special heat-resistant, light - resistant epoxy raw material is selected. As a new plastic material, EMC packaging materials are currently in the hands of Hitachi and a few large international material plants with strong technical strength. Hitachi chemical is the first to realize the commercial application of EMC LED packaging materials, with EMC material and patent for packaging, which leads to high price and can not make technical and market breakthroughs in the short term. Today, the price of the Hitachi EMC material that has been realized is about 6~9 times the price of PA9T TA112 plastic. White EMC is much more expensive than black EMC, in addition to the particularity of raw material selection, market demand is a more important reason. Semiconductor packaging black EMC global one year demand is around 130000 tons, LED white EMC demand is less than two orders of magnitude. It is clear that the price of EMC has a great impact on the production of mass production. Because the thermosetting material can not be recycled, it also has a great impact on the price of EMC scaffold. At the same time, the structure of EMC and the production rate will affect the cost of the scaffold. In addition, the overall cost and accuracy of the EMC support need to be improved, and the core technology is still in the hands of Japanese and Taiwan enterprises. At present, the cost is still the biggest obstacle to block the large-scale production and application of EMC packaging products. With the further optimization of the cost, the EMC market process is accelerating and will be transferred from the replacement of home lighting and commercial lighting to the professional lighting stage. Next, EMC packaging manufacturers also need to strengthen the brand and enhance the value.
