In recent years, under the guidance of the Ministry of Science and Technology and the Ministry of Information Industry, the semiconductor lighting industry is very popular. Among them, the LED packaging industry has attracted a large amount of funds due to its relatively low barriers to entry, and has achieved gratifying results. New LED devices are constantly emerging. The packaging level of high-power LED devices is close to the international advanced level and can be mass-produced. The development of new packaging equipment has achieved fruitful results. The independent innovation products are applied in the production line. The equipment with large market demand and high technical level has also started small-scale production, and sales have grown rapidly. According to the high-tech LED survey, high-brightness (HB) LED packaging will be a big business opportunity for 30% growth in the future; and the HB-LED packaging market will break through $35 in 2015.
Key components of LED packaging include chip placement machines, gold wire bonding machines, glue injection machines, phosphor coating machines, laminating machines, testing machines, tape machines, and dicing machines. At present, the domestic situation is: the laminating machine has been successfully localized, and the performance is excellent, which can meet the industrial requirements. The test machine, dicing machine and dispensing machine developed by some domestic units through the system integration method have also achieved good results. The results have been put into industrial use; chip placement machines, gold wire bonding machines, etc. are under development, and further efforts are needed to tackle the problem. In the illuminometer, light intensity meter, aging test bench, molds and fixtures, ovens, washing machines and other equipment, the domestic has already had the supporting capacity, and most of them do not need to rely on foreign imports. However, in the fields of test equipment (including spectroscopic color separation) and phosphor coating equipment, although there are productions in China, the gap in performance is still relatively large. Large-scale packaging companies are more cautious in adopting them. In terms of automatic die bonding and wire bonding of process equipment, less domestic equipment is used.
In terms of packaging equipment, the traditional metal wiring process is still the largest market for LED back-end equipment. Demand for laser cutting and laser stripping equipment is also heating up based on package sidewall flatness requirements and preventing substrate chipping; however, this small market has now entered seven companies. At present, domestic LEDQIYE is very popular on domestic packaging equipment, because mature domestic packaging equipment not only means its own product cost-effective competitive advantage, but also means the long-term industrial core competitive advantage; but on the other hand, it is impossible to promote domestically. Chemical equipment to risk the company's yield, cost performance, reliability, corporate reputation and other aspects. Therefore, in general, the current domestic LED packaging companies are not high in the localization of major equipment purchases.
To achieve localization of packaging equipment in China is an opportunity and a challenge, but the opportunity is greater than the challenge. Because the difference between the LED industry and other industries lies in the continuous improvement of the technology of LED products, but the price is getting lower and lower, which requires both the automation equipment capable of producing high-end LED products and the reduction of investment costs. Equipment offers a once-in-a-lifetime market opportunity. However, most of China's LED packaging equipment and packaging materials rely on imports, packaging companies are not large enough, packaging technology research is insufficient, the overall level of technology is not high, coupled with the shortage of LED packaging professionals, the principle, structural design, materials, optics of LED And too few people know about the integration of semiconductors, this situation seriously restricts the development of the industry. At the same time, the development of the LED packaging industry has also been hampered by foreign patent rights.
However, if domestic colleagues can grasp the development opportunities and adhere to independent innovation, they will certainly achieve a major breakthrough in the LED packaging industry. In terms of packaging equipment, it is necessary to increase the research and development and industrialization of packaging equipment. It is necessary to carry out in-depth research on packaging technology, and closely combine equipment research and packaging technology research, both of which are closely related, because the two are closely related. Mutual promotion. The author puts forward the following suggestions for the development of packaging equipment in China:
The government increased investment to support the localization of key equipment
The competent government departments should understand the importance of equipment manufacturing from a strategic perspective and increase guidance and support. For equipment that has been supported by the state (such as dicing machine) and related semiconductor equipment developed by the equipment unit, it can be given certain adaptability improvement and industrialization funding support, so as to serve the industry as soon as possible; Some key equipments were immediately launched, and the requirements for industrialization were put forward. For the equipment manufacturing technology that can be obtained from abroad, the state gave certain support to the cooperation units to accelerate the industrialization and localization of equipment; for other non-critical equipment, Through the support of three technical expenses, it will meet the large production requirements as soon as possible.
At the same time, it supports leading enterprises with independent research and development capabilities. These leading enterprises must have strong independent research and development capabilities or integrated research and development capabilities to meet the needs of customers' innovation and individualization. The government's support, coupled with close cooperation with companies in the industry chain, can speed up the process of improvement and improvement. By strengthening the above aspects, I believe that after about two to three years, China will be able to supply LED packaging equipment.
Manufacturers should work closely with customers
Packaging equipment manufacturing companies and equipment application companies should work closely together to develop. The application enterprise is familiar with the process and knows the actual needs. The manufacturing enterprise has the advantages in equipment manufacturing. If the two parties can cooperate and realize the complementary advantages, the LED equipment development and production process will be closely combined to form the complete line construction capability of the equipment and process. A breakthrough can be achieved in equipment development. There are already successful examples of this.
Independent innovation draws on and absorbs advanced technology experience
Independent innovation must not exclude foreign cooperation, and does not exclude learning, learning and introducing all advanced technologies and experiences. Moreover, independent innovation is not equal to building a car behind closed doors. Only by admitting backwardness can we continue to make progress. In the process of development, we should also actively carry out foreign cooperation based on the principle of mutual benefit and mutual benefit, which will greatly shorten our time to catch up with the world's advanced level. It is necessary to set benchmarks for foreign top companies, such as solid crystal and bonding of companies such as ASM and K&S, injection molding by Japanese monks and asymteks, test tapes of Japan Jiada, etc., bonding adhesives of Japan sanyu, Japan Shin-Etsu, American Dow Corning and other silicones, and quickly integrate resources to quickly imitate beyond.
Enterprises should pay attention to personnel training and marketing management
Gaogong LED believes that domestic equipment needs to further solve the reliability and accuracy problems, and it requires professional technical talents and engineers, so we can introduce talent strategy in large quantities. For large-scale state-owned enterprises, they are reluctant to buy domestic packaging equipment. Domestic equipment manufacturers must provide technical service engineers who are familiar with the customer's production process, provide customers with overall supporting solutions, and differentiate marketing with imported equipment. In order to be surprisingly successful in the competition. The government can also encourage LED companies to purchase domestic LED packaging equipment with preferential policies, and give some growth opportunities for LED domestic packaging equipment as a latecomer.
