Specific proposals and solutions for the development of LED packaging industry in China

In recent years, with the application of flash lamp, large and medium size LED display light source module and special purpose lighting system, the application of the system has increased. At the end of the system and then extended to the general lighting equipment, the use of white LED technology led (HighPower) market will continue to appear. On the technical front, the biggest challenge is to enhance and maintain the brightness, and to enhance its capacity, the development of the market has great potential.

With the development of LED production technology to improve the brightness of a thousand li a day, and life is prolonged, and greatly reduced the cost of production, the rapid expansion of the LED market, such as consumer products, and general lighting signal system, and the rapid growth of global market size. In product development, the development of white LED has become the focus of the development of the manufacturers. At present, there are four main methods for manufacturing white LED:

A blue LED+ yellow phosphor (e.g. YAG)

Two, red LED+ green LED+ blue LED

Three, UV LED+ red / Green / blue phosphor

Four, blue LED+ZnSe single crystal substrate

At present, the use of white light LED, such as mobile phones, digital cameras, PDA and other back light source, using a single crystal and YAG fluorescence. With the application of the mobile phone flash, large and medium size (NB, LED-TV) display light source module and special purpose lighting system gradually increased. At the end of the system and then extended to the general lighting equipment, the use of white LED technology LED (HighPower) market will continue to appear. On the technical front, the biggest challenge is to enhance and maintain the brightness, and to enhance its capacity, the development of the market has great potential.

ASM has more than twenty years of experience in R & D and production automation of optoelectronic components packaging equipment, the current industry there are many kinds of LED brightness method, both from the chip and package design level, to the packaging process to enhance the cooling capacity and increase luminous efficiency as the goal. In this paper, the development of China's LED equipment industry has some specific proposals. For discussion.

Specific proposals for developing LED packaging industry in China

The individual recommends that the state should support the development of LED technology and industry in order to support the development of materials and process equipment as the basis and driving force for development. In the process of developing LED technology and industry, it is suggested that China should take the road of "introduction, digestion, absorption, innovation and improvement". The specific scheme is as follows: under the support of the state, through the combination of the three parties of the state, the LED production enterprise, the equipment and the material manufacturing industry, the establishment of the Chinese LED equipment, material, manufacture and application consortium with the function of the incubator is established.

In order to grasp in a short time and improve the level of equipment manufacturing industry, promote the development of high-end LED China, recommended by the consortium to jointly raise funds (50% countries, 15% units of equipment development, chip manufacturing and packaging technology research unit 15%, LED chip manufacturing and packaging enterprises 20%) construction of a complete LED chip manufacturing and packaging demonstration production line. The demonstration line to solve the equipment development and process test, LED product manufacturing process technology research and verification, the realization of process technology and complete sets of equipment for the. Who participate in the construction of demonstration units, have the right to free use of the production line of related products, technology and industrialization of research and testing, especially LED production units, the priority to get the relevant research and commercialization.

For the demonstration line, the implementation of the three step strategy, the final realization of LED production equipment commercialization and localization.

The first step: the use of two years or so, the localization of some key equipment (the state to give some support for the bonus); has certain basic and common equipment has the price advantage of the use of the principle of market competition, to access the system supporting the preferred (by formulating standards); for some difficult in the short term, localization no country should arrange equipment, research, and complete the production prototype.

The second step, the implementation of the scheme from third onwards, the first step involves two key equipment to solve the production process adaptability, production efficiency, reliability, appearance and costs, with the domestic support and supply capacity, key equipment to complete the production pattern of commercial machine (gamma type machine) development.

The third step, the implementation of the scheme from fifth onwards, all equipment for the first and two steps involved in the international competition ability, in addition to meet the domestic demand, to occupy the international market; key equipment can meet the requirement of the industrial production and has the bulk supply capacity.
